The idea is to race them FPV stylee, whether that be timed around a course or a full out everyone on course racing.
All getting the same airframe and power plant (yet to be decided).
Should be fun!!
Steve
Fun in the sun, with a bit of FPV serket racing.
;D G :run:
Race on! :o ;D :laugh:
That is excellent, looking forward to seeing this ;D
CAN I PLAY TOO :D
dizzy
i got a load of 22 size 1800kv motors here that we could use to start, wont be mental speed but would make good racing.
Or myself and gary have KD 200kv jobbies, I'll see if I can dig out the details... the 2200kv jobs are the way to go for speed, prolly good for 90-100mph.
scratch teh KD, just remembered mines bust.

And that quote is exactly how me and the wife got together! And it all started with an e-mail snowball :-X
these are the motors I have...
http://www.rctimer.com/index.php?gOo=goods_details.dwt&goodsid=113&productname= (http://www.rctimer.com/index.php?gOo=goods_details.dwt&goodsid=113&productname=)
could be a good balance between speed and flight time.
the motor calc gives us around 80mph on 5x5 a prop with those motors, so we might get 70 realisticly.
it mutters something about the prop stalling but we'll suss that out :)
Got one on order :D
dude, i got like 8 of them, you coulda had one.
I'm in. All ordered and very excited.
nice one splashy! where ya located?
ok, so I'm now thinking about FPV gear, for size and weight its got to be 5.8 altho this might put some restrictions on the circuits, but we'll see.
With me always looking to get everything as cheap as possible and having seen the great results Gordons got from the bare bones range video offering I started to do a little research this morning.
The Range video TX is a TX5823 and the RX is a RX5808, which I've found around $10 cheaper here (for them both)...
TX = $16 http://www.crazyshoppingcart.com/58g-200mw-wireless-av-transmitter-module-p-5438.html (http://www.crazyshoppingcart.com/58g-200mw-wireless-av-transmitter-module-p-5438.html)
RX = $13 http://www.crazyshoppingcart.com/58-receiver-wireless-av-module-p-5441.html (http://www.crazyshoppingcart.com/58-receiver-wireless-av-module-p-5441.html)
Altho I was very impressed with gordons setup the TX runs on 5v which is an issue as it means incuring extra weight and loss of space do to either running a voltage drop thingy or carry an extra power source to supply 5v.
So this leads me to consider this one which runs on 12v but is yet to be tested by anyone I know or indeed I am yet to find anyone using it for fpv. Altho I've just done some reading and theres some opinions that this may be a typo by good luck and its actually 5v (the image shows a 2.4 tx apparently).
TX/RX = $35 http://www.goodluckbuy.com/5-8g-200mw-wireless-av-transmitter-module5-8g-video-av-receiver-set-for-fpv-system.html (http://www.goodluckbuy.com/5-8g-200mw-wireless-av-transmitter-module5-8g-video-av-receiver-set-for-fpv-system.html)
Which leaves me all a pickle...
Having seen Gordons system work so well I think I'll go with tried and tested and order the TX/RX from Crazy Shopping Cart as they're only £20 including postage... I'll have to deal with the voltage problem.
hmmm slight prob, when I go to order through crazy shopping I get paypal in chinese :o
Pasty - this is a great idea :)
On the voltage thing - can you not use the ESC BEC voltage to get your 5V ? or if its low power enough, a 7805 voltage regulator hung on the balance connector of the main battery?

Taunton .. but might be able to travel .. will have to see how long the new plane lasts.
Teejay ... how do they handle crashing ?
I have one of these Steve, I'm going to run my FPV and my HD key cam of it hopefully. the range Video 5.8ghz has 8 separate channels and a clover will give us 1300ft of clear footage which gives us 2600ft radios, that's nearly 800m, or gust under 1/2 mile that's not a bad course size

I have in my drawers a rather good collection of power supplies (2 x the Range Video one) and 5 x variable output and 3 x HK 5V BEC. If you would like any of these just let me know and I will post you one out on Monday.
I also have a couple of 3.3V BEC since the other tiny 200mW TX i have purchased have been 3.3V
nice one splashy... thanks!
I took the plunge and ordered the same 5.8 gear as Gordon but from CrazyShoppingCart.com for £22 all in.... not bad!
I'm gonna have to get ordering as well then! :laugh:

Yes, I did as well.
If you need the 3.3V BEC or DC-DC just let me know.
the more I think about it the more I'm leaning towards using a second battery for the vtx, its not gtoing to weigh much more than a BEC or a stepper and will give you a nice clean camera image... so you save on the weight of an lc filter on your power lead.
I have been running my 3.3V VTX on 3.7V with a Nano Tech 300mAh and have had no problems with it. I do think however that it would be more prudent to run it off 3.3V via a BEC.
I have been looking at the specs for the Crazy Shopping Cart VTX and RX and cannot work out what exactly I am going to receive. The site states transmitter frequency:5725-5865MHz; 8channels but the data sheets (from foxtechfpv) give
5705
5685
5665
5645
5885
5905
5925
5945
I am inclined to believe the foxtech frequencies which mean that it will work with a 305 receiver (which I have 3 of).
If anyone has one of these VTX/RTX units then it would be good to know whether the frequencies are as stated on the site.

If this takes off we'll have plenty of time to run extra races on a race day or race weekend, so to add to the one design class we'll probably have an unlimited class for running whatever you like.
The emphases is more about having a laugh and excitement with minimum fuss rather than serious racing so rules and regs etc will be kept low on the agenda.
All races will be held over private land with the agreement of the land owner (I've got 3-4 big land owners I can get onboard)...
We should have a mix of circuits including beaches, flat land, old quarry workings and valleys.
I've even got a gazebo we can use as a race tent :)
I should also say that these races will be geared around testing a pilots skill rather than how many watts he/she can cram into an airframe so the circuits wont be flat straight lines with few corners, the circuits will include natural obsticales as gates, turn points etc. There will be long sweeping turns, hairpins and chicanes with the turn points being natrual obsticals that you have to fly AROUND below there total height rather than over.
thats enough thinking for now :)
Cool - wish I lived down your way to join in. Billy no mates up here.
BTW, I had teh larger version of that plane. Flew like a dream one set up correctly. Probably the nicest plane I've flow. The foam was crap though. Snapped if looked at it. I think yours are EPO though

Bought the same, sorted!
wow, just checked HK and my order is ready for dispatch... so with EMS I may get it by the end of the week or early next week... have HK pulled there finger out? Last time I ordered from them I think it was about a week before they started processing my order.
The vtx/vrx has been dispatched by Crazy Shopping Cart too...
I best start looking around for some circuits!
O yes, going to get some practice with the circuits are we. :+
I haven't received anything from HK yet, no messages.
:) G
Damned right! :P
You need to find/create a circuit or two down your way G... we need a good selection of flying... we need permission to fly on the land remember.
No mails? did you go EMS postage?
All my gears on its way.... and I got tracking numbers to prove it...wooohooo! :D
hmmm time to decide on the colour scheme, I had considered camo so other racers cant see me very well.... then I thought I WANT people to see me shredding them up.... I'm going to have "loser" written on my trailing egdes :D
I have made all my clovers for channel 8, so you and Gary should think about what channel you won't.

parcel force, handling charges then.
:( G
I told you the other day, parcel force always take EMS as its a courier service, doesnt always mean you'll get charged, thats only triggered if its stopped by customs and they want their cut.
If they deliver and ask for cash I'll make sure I have the parcels in hand, pay the customs fee then tell them to ram their handling fee where the sun dont sign as I never contracted into them "handling it" and have paid postage fees already.
With our race planes about to land on our door steps I thought i better think of a more catchy name for the series...
Flying on the most southerly point in the UK I thought South Point Races was ok.
My ones hear, I cant believe, haw good these are for the cash, I will have a better look later after work. very exited.

mine too!
What a cracking little model, looks great! the foam and molding are excellent!
My 5.8 gear arrived too... to the workshop robin!!

I cant beleive i am at work while my model is down steves workshop!

Hmm but how??
Hey guys,
The Tx module from GoodLuckBuy
http://www.goodluckbuy.com/5-8g-200mw-wireless-av-transmitter-module5-8g-video-av-receiver-set-for-fpv-system.html (http://www.goodluckbuy.com/5-8g-200mw-wireless-av-transmitter-module5-8g-video-av-receiver-set-for-fpv-system.html)
really is able to be powered from a 5v supply (or even a 7.2v (2s) supply).
It has an inbuilt 3v3 voltage regulator.
If in doubt, open your VTx and look for a little v-reg (might be one in top left of image below, but mine has a zero ohm resistor so it's powered by whatever voltage you put into it!).
If it doesn't have a 3v3 v-reg, you can remove the 0 ohm resistor and add a v-reg.
http://static.rcgroups.net/forums/attachments/1/7/0/3/6/4/a4614321-217-Tx1.jpg (http://static.rcgroups.net/forums/attachments/1/7/0/3/6/4/a4614321-217-Tx1.jpg)
It will run on a 1S but in the long term, may not be the best thing for it.
We sussed it out over on RCG ;)
I have mine built on a little stripboard PCB and put a 3v3, 800mAh, LDO v-reg on board to feed the VTx and the 3v3 2g camera from 7.2v (2S or balance port of a 3S).
Nigel.
great info Nigel... thanks
We all went for this one however...

same as the range video offering but a bit cheaper.
I was going to run it off a seperate single cell... I'd like a clean signal for racing.
Crazy Shopping Cart was a long shot in terms of I hadnt heard of them before but my gear arrived very quickly (same as the EMS delivered parkjet) and was well packaged... will order again from them for sure.
nice fined Steve, exactly the same as my ones, just nearly $4 cheaper.
;) G
postage was way cheaper too.... it all adds up ;)
OK the Build is coming on, I have fitted 2 MG90S metal geared Servos and a BC-2208/12, 1800kv motor and a 5X5 APC prop with a 30A ESC, and a 1000mah 11.1v 25c lipo.
The setup is pulling 10.2A at Full and 115W to 120W.
Its a sweet model and I cant what to get it going.
;) G
great guns G, did you use the carbon motor mount? I read that it can bend a little and being high off the thurst line it can push the nose down under hard throttle.
I'm going to use the stick mount to move the motor onto a better thrust line and to make it more streamlined.
Did you use the glue that came with the kit? funny stuff isnt it, like rubbery epoxy.... I use it to put the wing halves together but CA'd the spars and fins.
I've got the frame toegther but left her over night to let the wing joints set.
I wondered whether we can use one of our canopies to make a former, take the canopy shape then adjust the former so that its suited to our needs... like a better shape to take the camera and a flat area to mount the VTX etc... then slap adjusted former on the vacuum former and bingo :)
those amp and watt figures are encouraging, all very safe.. plenty of room for playing, a 6x6 should give a bit more pace... we'll find out whats what on our first test day :)
I have drilled an extra hole between the carbon motor struts. to take away the bend, but then I mucked up a bit, because I thought I had to glue in the stick, than screwed the mount on top of it, I then watched the video again and no test they had glued the mount to the poly, I will still try it out, because if its OK it will strengthen up the rear of the plane.
I used UHU Por and epoxy to glow the wings, and Gorilla glow for the spars, then covered with a strip of reinforcement tape.
I have fixed my canopy, but if you still have yours, you coled fill it with something, and use it like a mould, then re Sharp and vac no problems.
;) G
OK maiden complete, way to much wind, but just couldn't what to try it, I'm really happy with it and if it handles this wind it will handle anything.
FPV gear going on tonight.

I took it out tonight when the wind drop and it went like a bat out of Plymouth. I have a 2200kv at the same size motor hear, but this one is fine at the mo.
I have got to tack the wood out and lower the motor a tad, its fine when it going, but tends to nose dive at launch if I throttle to fast.

Think they maybe the same camera, if so they are a cracking bit of kit for the money
And Fu at Foxtech is a good bloke to deal with
Thanks Si, even cheaper again...ideal.
Does being PAL or NTSC matter for us? The PAL one is out of stock.
All depends what recorder you use, if it's mini dv tapes like me forget it, but if it's straight onto a memory card or hard drive it don't matter
I dont record my flight cam feeds... sorted :)
Hear is my first FPV flight, it will take a bit of time to get use to it, but it will be a scary day at the races.

Looks good G :)
Looks slightly unstable, but fun to fly :)
Thanks guys, its not easy to get going, take off is really bad, it wants to dive on acceleration, so it needs up elevator at the launch, until it is up to speed, and I can't throw with my left hand, so I got to get on the sticks quick.
it is twitchy, but I'm sure it can be tamed, it flies beautifully LOS.

Regarding the nose dive on take off. had this problem with my wing If you cant move the motor down physically you can try adding some downthrust ( e.g point it downwards ). Depending how its mounted some washers under the mount screws or bolts would do.
I found I had to point the motor at the centre of the wing section where the c.g is. I find the nose will now lift on takeoff so I then need a bit of down elevator at full speed. ( Just be testing my new wing you see. Hope to get some photis etc soon)

get a stick mount like us G, job done.

Those are looking very cool guys
Can't wait to see the race videos :)
Come join the fun Teejay! ;)
I thought I'd add a little info on what I've done different on this and why...
With us all running the same airframe and power system the three main factors that will impact on straight line performance are Lipo condition, setup (reflex and cofg mainly), weight and drag.
Lipo condition is out of our hands to some extent, its either a goodun or not, looking after our packs over time is the best way to keep up performance.
Setup will come as we test the planes and theres likely to be an optimum config that we'll all end up using to some extent.
Weight is dictated by the gear we're using and something we may or may not find that important aslong as we're within a few grams of each other. Unfortunetly I've had to use some heavier servo's (14g each) as its all I had.
Drag I think is the main factor that we can effect directly, with this in mind I'm doing all I can to reduce it (within reason of course)... the stick mount takes half of the motor and mount out of the airstream, I've mounted the ESC internally as thanks to Gordon we know the powertrain is only pulling 10amps or so WOT meaning with a 25amp ESC its not going to need cooling, I've sanded off the mould seems and tidied up the moulding on the trailing edges (both wings and fins) and finally all joints resesses etc will be taped or filled.
This is the type of motor mount we're using, a cool thing about this model is the motor thrust line is moulded into the airframe so any straight mount will give you the required motor angle.

It's a ruddy long way from here matey and I've still yet to actualy fpv a plane DOH ! (i'll get it done one day :) )
The big fish sells those type of stick mounts (square outer tube)

Nigel.
good find, thats actually the one I'm using but couldnt remember where i got it from... nice one.
nice one Nigel, I have ordered some thanks.
;) G
thats mine maidened, it didnt need any reflex so that must be fixed in the wing section, its not crazy quick but fine for our purposes... I blatted it around at full throttle for a few mins then landed to check heat in components... all good.
Now its waiting for the cameras to arrive and chat gordon up some more to build us some CP antenna.... or I'm stuck with the omni.
Nice one Steve, I'm glad your up and going, hows Gary's coming on.
I have panted one side of my one, to help my spotter tell which way round it is.
:D G
(http://s14.postimage.org/roto9bj4t/Park_Jet_racer.jpg) (http://postimage.org/image/roto9bj4t/)
Nice G!
I've got some yellow and black paint.
All that's left on mine to just maiden it is to solder on the ESC and sort out the canopy.
Camera will be here in about a week.
How hard is it to make a clover leaf G? Could do with some help on that if you can. Maybe come over your place and make a couple?
looks like i got some twistr on one of my wing panels... my fault its not glued straight :(
it'll trim out but its etxra drag
Come over whenever you like Gary, their not that bad really, just a bit time consuming.
I could do with another one, So we could make them at the same time.
My brother has ordered a plane now, so I got him to order me a spear one, I can see this one in bits in the future the way I fly. :laugh:
:) G
Cool G,
You got the parts or will we need to order that? If not then can you let me know what to buy. If so then am happy to pay for the bits.
Weekend good for you? Sat morning to afternoon?
I'm working from 4pm to 8pm on Saturday, so morning is probably best.
I have the wire and about 600mm of coax, but I haven't got any of the SMA things.
:) G
can we forget the sma's and solder straight onto the board?
Heres a little practise track I just penciled... using my old mans land, its on a slope so you're flying up and down hill and the right hand straight is done below tree cover.
(http://s18.postimage.org/sxedqvd1h/practrack.jpg) (http://postimage.org/image/sxedqvd1h/)
If you have RG316 or similar Teflon coax, then solder straight to the board.
Nigel.
My Park Jets finished. Hope to maiden it tonight before it gets to dark.
AUW is 290g. Seems very light indeed.
mines 320g minus fpv gear... not aot init... will it make a difference? we'll find out :)
I have soldered the clover to the VTX but I have used the SMA on the VRX. my one is 339g with both battery's and FPV gear ready to race
:) G
thats light G, looks like mines going to be the fat minger of the group.
whats your cofg?
Did you notice any toque roll when you throttle up quickly? mine rolls over quite a bit
Practise circuit number 2.

south point races logo?
just something i nicked off the net.
(http://s16.postimage.org/53ht02toh/southpointlogo.jpg) (http://postimage.org/image/53ht02toh/)
there is know toque roll, but I have just put a straight through mount like you now, so perhaps there might be now, on the original mount, the motor is pointing back to the right, perhaps that makes a difference.
the CG on my one is slightly nose heavy of the slots with the FPV kit on.
:) G
hhhmmmm might be the bigger prop I'm running.
Racers...
(http://s14.postimage.org/bnazj3oh9/IMAG0323.jpg) (http://postimage.org/image/bnazj3oh9/)
Now that looks bloody good fun!
Hope you guys record some of this action for us all to watch :)
there will be plenty of video thats for sure... there will be fixed cameras on track and someone on a HD camera ship filming the action from the air... plus the onboard stuff.
The race teams gathered at Gordons work shop today for a clover leaf antenna master class followed by the first test flights with all our planes up at once... which was rather fun :)
They fly good! Not to fast and that's okay as we'll end up in trees one after another!
Clover leaf and skew planar pretty much sorted. Thanks for the parts and explanation Babs :laugh:! They should do us nicely.
Come on cameras! Its quite annoying having to wait for just them to get FPV going!
just like you said G... I ripped out the channel 3 track on the vtx :(
So I've gone hard solder over channel 1, 2 and grounded onto the metal case which makes me fixed to channel 4.
This should be funny to watch
Major disaster! Steve broke the soldering iron!
Stopped play for a few days no worries as we have to wait for the camera anyways.
We were ripping through getting the vrx housed and wired up as well. ;D
Channel 3 track riped out and a broken soldering iron, good going, ;)
your most welcome to the parts mate, It was nice to finally meet you Dave. :laugh:
:) G
i blame it on the stella :-[
7x7 apc prop for the win, 5 min flight at wot and battery it only slightly warm, screams around! Covers so much ground so fast!
Also moved my battery back 1cm and its flying much nicer with less up in it.
homebrew heith robinson style 5.8 receiver casing with homebrew skew planer thingy :)

5.8 receiver module used as per earlier in the thread, soldered up to a phone doowap and a single cell lipo in the case for power.
All my stuff arrived this morning. Very cute plane.
nice one splashy, cracking little plane isnt it... did you go for the 5.8 gear like us lot?
It is certainly a very little plane. So small in fact that it flew in right under the delivery radar. I did go for the 5.8 gear have been using it on my mini quad.
Not sure that I will use the little receiver modules though .. if anyone wants one then just let me know, I already have several of the 305 receivers.
Just got to find some free time to build it.
Which 305 receivers have you got Splashy
I'll be looking for a Foxtech one very soon (not the same frequencies as the Airwave/Fatshark type)
Ch1:5705mhz
Ch2:5685mhz
Ch3:5665mhz
Ch4:5645mhz
Ch5:5885mhz
Ch6:5905mhz
Ch7:5925mhz
Ch8:5945mhz
I have one that I got from Foxtech. The others are from different sources but they are all the same in terms of the frequencies.
Let me know if you would like one, will sell you one at cost.
The new camera arrived yesterday and is now fitted, she is all ready to race.

Nice G!
I've just ordered one of them as well. Ir was my birthday and was given some money that i was told to buy some toys with! I'll have 2 nano cameras for my 5.8 gear now :D
Which servos are you using? I had a couple of 9g servos that I thought I would use but on checking it states 4.5g servos. There are quite a few of these available. Which ones are you using.

Hi mate, I'm using Tower pro MG90S but I had to cut the poly a bit, I just had 2 lying around, thy work fine.
;) G
Excellent. That is what I have already. Pleased that I can use them, just was not sure about the weight . don't know how critical it is on these planes.
I got mg90's in mine, a few extra grams here and there won't matter, mine are 14g a pop. Make sure you sink them in flush... unlike Gordon ;)

Is the flush bit really important then?
I don't notes a difference mate, when there's a camera stuck on the front entryway, it flies great.
Talking of Flying great, hear is the latest new camera test, and I palled some G's to see if the clovers still give a clear view, whilst spinning and as you can see its fine, these things cover ground quick.

New camera test on the Parkjet.mp4 (http://www.youtube.com/watch?v=b2j-kKgLuac#ws)
Geez, I nearly threw up I got so giddy there G, you could have warned us ;D
Do I detect a bit of a 'smudgy' image running from top to bottom in a narrow band on the left of the video G?
If so, mine does exactly the same when viewed through my goggles (and recordings), maybe it's an inherent thing with them?
Nigel.

I was putting it down to the new camera Nigel, I fault the lens was skew or something, I haven't noticed it with my over ones, but I just had a look and its defo the camera, it is on all the little cameras, including the 1g ones from Simon, I don't notes it in the Fat Shark goggles.
I have a good camera on the mini Sky walker 5.8 setup and its fine, as you can see in this clip.
close as you like.mp4 (http://www.youtube.com/watch?v=a8Ak7MUyysc#ws)
Lol, the Park jet dose make a big filed feel small Splashy.

;D :D
These limited Parkjets arent far off the 100mph mark ;)
You're welcome to join but the PJ class is a limited class so you have to run the same airframe and motor, we'll be running a few classes one of which being unlimited, your fun fighter could compete in that but a 100mph fun fighter is going to be slow compared to other racers in the class. I'm tempted to get another PJ or the mini radjet and run 4-5cell with a much higher kv motor, should be good for nudging 140mph.
The great thing about running the smaller light foam airframes is that they dont need large expensive gear to get them going fast, we're going bleddy quick with the limited PJ's on 15 quids worth of motor, esc and lipo.
Oh I found a little qwerk of the PJ, zero the throttle and stick it into a spin with full elevator and aileron, let it spin up a bit then slam in opposite aileron, it snaps the other direction and goes into a much faster spin which is unrecoverable via flight controls, you need to let go of aileron, elevator and give it full beans on the throttle to get it to push out of the spin.
This type of spin is quite common on this type of planform.
Give it a go, its pretty cool :)
Do it with a bit of height mind as it can take a few spins for the motor to push it out.
i just orderd one ;D i recon my stock fatshark resever will be small enugh for me
what power plane we going with ive allready orded the airframe;D
this is the motor...

on the video at 117 in, It was spinning in the wind and it suddenly went in to a flat spin and I nearly lost it, I dropped of the throttle, because I thought it was bust, then managed to pull out before it crashed. :o G
im all orderd too this will be fun ;D
can i buy that moter from someone ??
Yeah, rctimer... order now and you will have for when your other gear arrives.
Switch and charging harness added to my all in one VTX box.

not far off G!
I've followed your lead G with both vtx location and locating pin in the hatch thingy, the last thing we want is the canopy containbing all the fpv gear to come flying off :)

Pasty,
Did you manage to get around that Chinese paypal page at Crazyshoppingcart.com ?
Or did you buy the vtx from somewhere else?
I did something in paypal I think, which then told me what I was buying and the price, I did someting like take the URL from the chinese paypal to the uk paypal.
Not sure tho :-\
Thanks Pasty, Finally managed to pay but not sure how I did it either ha!
pasty that plane looks soooooooooo good please never crash it haha :D
Crashing is inevitable I'm afraid :)
Have you seen him fly? I've seen it after totalling mine. :laugh:
is yours dead Gary?

Hows about an unlimited semi scale warbird class?
I've got an itch to scratch build something and was thinking about one of these...

Hey G I found an ok 3view of the tiger cat, you recon we can cnc the fuz and engine nacelles?
Do the nascelles in two halves and the same for the fuz but maybe in a few parts... i got blue foam as a material.

Gary
Our cams arrived today (finally), mounting them tonight so should be good for her fpv maiden tomorrow... woohooo!
pics to come
I've fired up the 5.8 fpv gear and I have to say I'm very impressed, i left the camera/vtx etc in the workshop and went for a walk up the street and got surprisingly far, it was only when i walked behind my house I lost signal.
The camera is also very good, the night vision is excellent, it was like day light under and around street lights, easily flyable.
well chuffed
nice one sounds like your all set now.
;) G
My 5.8 gear is also installed and pretty much ready to race! Roll on Saturday! And damn to working. ;D
Nice one guys! Whilst i wont be able to join the races (4hr drive, though will be holidaying in Cornwall in June), This thread has inspired me - I like the idea of cheap, light, small 5.8GHz. Figured it would be good in an EPP mini swift or Gordons fox.
So, Ordered my VTx and VRx from crazy shopping cart (cheers Steve!). They are actually a subsidiary of the trusted SDS hobby that many people use. Delivery was 10 days.
Now I'm trying to figure out the Tx pinout...the range video site is useful (similar unit). how do you power it? Bit worried about Gary letting the smoke out :(
Perhaps I'll get a 3.3V reg from maplin and take 5V from a spare channel off my radio receiver?
Think I'll get a cam + lens like yours Steve...
Keep up the good work!
Matt

Hi Matt
I'm running mine on 1 cell also, myself and GaryB have noted that they get warm/hot, particularly the underside of the vtx around where the antenna connects.
We'll see how long they last but I've had mine fired up for a good 8-10mins and the heat seemed to level off so hopefully its fine.
TX pin out is marked by AV on the back.
and 4hrs drive isnt much if you come down for a race/general fpv weekend ;)
What capacity 1S batts are you using on that vtx/cam?
and I wonder how long they are lasting ?
I'm using an old 1000 pack which only takes around 600... 600 gives around 1.5hrs safely. But being 1s you can use one of your bigger 3s lipo to run your field charger and charge in the field.
That's good, never realised it would last that long!
Hey steve, did you get that cam from foxtech, the ones I mentioned??
Quote from: BigMouse on April 14, 2012, 10:51:48 AM
That's good, never realised it would last that long!
You can roughly work it out by looking at the mah used by each device running off the lipo.
Simon.... yeah it is, took a while to get here but they seem pretty good. Altho I was test flying the other day with a big dark cloud blanking the sun and I have to say the image could have been brighter... further tests to come.
I've ordered another 5.8vtx for a spare and using on my multicops.
I finished mine last night. Went with stock trim in the end.
(http://dl.dropbox.com/u/46839301/Forums/FpvUk/random/DSC00505.jpg)
Ended up in bed all day 12 hours sleep! I was feeling like crap and could not get my head off the pillow! Missed a great FPV day, she will have to wait till the weather clears up.
I got 3 flights in today... I moved everything back that I could to get the cofg further back and it handles much better now, altho its at its most stable with the throttle wide open which is quite unnerving if you're trying to get a measure of the thing.
I flew all flights from launch to landing through the goggles, both launch and landings were an easy affair without drama.
The light was suffering as rain headed my way but the camera image doesnt offer that much detail, maybe some good light will help that.... more testing needed.
Following this thread with a smile on my face. Sometimes the research is as fun as the final product.
How much are these things coming in at from scatch?
Got luck @ the races. :)
think its:-
airframe and one 1000 nanotech pack £35 delivered
motor and esc £14 delivered
servos about £12 for both
RX whatever you got kicking around.
£61 total
vtx/vrx modules were £25
camera £25
but unless you're quick on the old sticks I wouldnt recommend the PJ as an fpv platform... tis good fun tho :D
For some reason, I cant upload the picture in the normal way, but do have a look at thees links and see how the new full size camera is mounted.

Great work G, looks excellent
nice job G, if i cant get a better image out of this mini cam i might have to do the same.
Thats looks such a clean way of doing it. Well done Mr.G
Nice!!!
Now what you need is a vac formed part to keep it stream lined. With a decent cam it should be good quality even with the defraction going on. ^-^

Thanks guys, I have channeled some grooves besides the camera and some holes in the bulkhead, so that air runs past the camera and throw the inside of the fuselage, should keep everything cool.

Cool. should be good fr speed
Really looking forward to seeing these in action. Any dates for a race yet?

Hi Andy
We're still testing the PJ's and the setups to get a good measure of them before we start racing, we're hitting barriers like the little cams not being detailed enough (might try refocusing mine) for low flying and with the fpv gear up front its tricky to get a decent cofg... I'm having to add lead to the back of mine.
Prolly going to be a week or so before we have the first unofficial race/test day.
There is of course the unlimited class but not sure what the other guys have for that (interms of racers).
I like the idea of having a few race weekends through the summer, there will be circuit racing and time trials but also none speed challenges like duration comps, bomb drop challenge, commando course etc... you get the idea.
should be fun :)
ahh sounds soo good i just hope the post man hurrys up and customes dont try and steel all my money lol

Yep! I would definitely have a go in the unlimited class just for fun :)
I hope we will be in Devon this summer so might be able to make it down to West Cornwall for the day.
My wing goes OK though cornering is probably not up to pylon racer standards, but I would be embarassed to be beaten by an EasyStar lets say :o
I found since moving to a wide angle lens that its much more difficult to figure out how high you are close to the ground. I suppose the alternative is a narrow view lens and a good spotter to tell you where to go!

Andy
If you do get down this way Andy, give me a shout, I would meet up, even if there's no raising happening, its always good to meet up and have a fly
I will be happy if I get round the course in one piece.
hopefully there will be lots of spotters to pick up the peaces.

Well I hope you're all going to report all the "near misses" to the CAA like good children :)
Yeah i reported Pasty for almost hitting me with his plane last week, for some reason they were not interested?!
what... you mean they may have better things to do?!.... surely not...
Ha Steve, I fond this, thay might be small enough to fit thees plans and calm them down a bit.

Thanks for the info/encouragement, Gordon/Steve/Gary! Watching your testing with interest ;)
Sorry to hear about the burnt out Tx...never heard of that happen, so assumed it was the VTx. Have you been running it with the antenna collapsed for some time?
Glad 1s lipos are doing the trick. I'm considering breaking one of these:

Nominal charged voltage is 3.3V, no fire hazard, lighter...we love 'em in the 50cc/100cc aircraft...
Re the Tx pinout- are you grounding the cathodes of your CP antennas (or the braid on the coax lead) to the nearest "GND" pad to the "ANT" pad?
Thanks!

Hi Matt
Those life packs look ideal.
we've ground the antenna to the metal case/heatshield thing, saves farting about with soldering to small pads.

No mate, its a long story but the end result was polorised power cables that let out a lot of magic smoke when plugged in.

to cut a long story short he plugged it in the wrong way around ;)
Yeah cept i have swapped over cables for a transmitter that had the wires the wrong way round... then used that battery in the one that went pop!
Aye, the LiFePo4 are great; that's what I'll be using.
D'oh Gary! We've all done something similar...damn electrickery ;p Any chance you're breaking for spares?
:)
Good call on the cathode...I guess any ground works. I think I need a smaller soldering iron...these 5.8TXs are teeny-tiny in the flesh!!

sorry thats the biggest it was allwing me to upload
1000mah nano teck 3cell
some 30 amp esc i had lying around
i think a 2200 kv moter but not too sure
and htx 900 servos
the stock moter mount broke before i flew it and chewed up my vertical stabiliser but after some epoxy to the moter mount she was ready a bugger to launch but she flys nice under power as soon as i glide but drop the speed it goes into a flat spin only recovable by lots of power which is annoying but fun i really enjoyed it but my moter mount played up again and anouther part came unglued which needs addressing but apart from that shes some bird!!
Don't bother with that motor mount bud, go for one of these, we all have.

:) G
yep we're all running stick mounts, if you do go over to a stick mount if you dont like torque roll as you punch the throttle put in a little left thrust (left if you're looking at the back of the plane).
It shouldnt be going into a flat spin if you try to glide, that shouts you got something set up wrong or a combination of things.
Hear is the new camera test, it doesn't look as good as my recording, I guess it YouTube, but you can get a good idea. I'm well happy with it, I have the OSD cable in the plane, so if I need to make any Moor adjustments I can.

thats the ticket G, altho I wouldnt like that fish eye effect while flying... what mm lens is it?
i'm not sure Steve I have a few different lenses, this is the widest, I will see what its like.
hear are a few pictures, the CG has come out perfect.

I think G likes yellow play dough :)
Awesome as ever G
Nice G :)
Am i right in thinking that you have cut off the front end and put the camera there?
Ahh thats what i saw on his trousers. I was getting a bit worried tbh :P
Thanks guys, yes Miles, its stuck inside, it was to big to put on the outside.

Or you could come down for a long weekend for some unlimited racing, g's running his fox in that so least you know you won't come last :D

Right lads, we all have working PJ's shall we pencil in a test day?
I'm up for it, but my next day off is Monday, then the following Saturday, I will have mornings or afternoons between, I'm free this Saturday after 5pm, its still nice and light same for Sunday.
:) G
PS there is always the morning, but that may conflict with peoples bed times. :P
it needs to be a weekend as Gary works all week and we need to make a day of it to get the most of the drive and fuel if we're coming down your way.
I could come down for some unofficial testing tho ;)
on a side note, I'm still trying to work out how to get a KK board into the PJ.
how about Saturday the 5th of April then, for the first race event.
;) G
March, Aprils almost at an end! I like the way you've gone from test day to race day G! :laugh:
sorry may 5th
:D G
ooo next weekend... its a date!
Where? i need race details!!! :+
I don't mined were its helled, I can travel.
;) G
North Lincs? :)
skyhigh123 (tim) and i might just have a couple on order now :laugh:
may be 2 new entrys into the nationals race ? LOL
simon.
p.s.
what power sytems did you go for in the end?
just so its all fair ;)
nice one Simon!
this is the motor we're running...

Purely because I had a load of them kicking around from a small hexa copter fettish I had :)
its looking a bit windy for PJ racing this weekend :(
We could race unlimited tho :)
I'm still testing my larger plane, could give it a go though! :laugh:
Just got back from a top test session with the PJ, a lovely no wind evening with a nice warm sun.
The first flight went well, I quickly realised she was too twitchy but thought I'd continue flying this pack and adjust when i land for the next pack. All was good until I tried a long fast inverted pass and tried to climb out inverted... which result in the canopy being ejected... and the canopy holds my fpv gear!
I flutter to the ground helplessly and quickly bin the throttle hoping to avoid a full speed ground encounter, with goggles thrown to one side I run across the fields fearing the worst...
surely a full speed inverted crash would be terminal? But when I arrive at the crash scene the PJ is sat there right way up with not a scratch on it and the canopy sat a few feet infront... after a quick jump for joy I see I had got some damage, the canopy had gone through the prop cuting the plastic in a few places... oh well... battle scares!
For the next flight I reduce the aileron dual rates to 40% and stuck in 20% exp, what a difference, she was rock solid and a blast to fly.
Thankfully the camera performed ok in the much brighter light but it did black the ground out when the low sun was in view... hey ho I can live with that.
Bring on the racing! :D
I dont know why but I've been hankering for a twin engined fpv ship for a while, I've been eyeing up the j power P38 but its 100 smackers atleast regardless of where you get it from.
So while looking around the shop I saw my old Ute fpv ship which handlely had some motor pod things already made for the wing :D
Down she came and onto the workbench, shess not much to look at but on a windy day her weight could help in the unlimited race class and with two 1800kv motors swining 6x5 props it should be good for 80mph.
I'm going to get rid of the rudder, associaed servo and cut down the elevator to reduce weight at the back and get shot of unwanted drag.
It'll be something different and fun I hope.
(http://s18.postimage.org/63566vng5/IMAG0452.jpg) (http://postimage.org/image/63566vng5/)
I just put my pj nose down onto leccy scale and zero the reading, fired her up and I get around 650g of static thrust.... no wonder they accelerate vertical my PJ is only 360g all up! :D
Speedy ships. :laugh:
;) G
My twins almost ready for her maiden, just need some props :/
She looks a bit goofy but I can live with that.
(http://s15.postimage.org/oz8i8giyf/IMAG0490.jpg) (http://postimage.org/image/oz8i8giyf/)
the motors look tiny :o
Its got motors on it? :o :+ :P
thay do look tiny, whens the first flight then.
:) G
they're 2830's of around 1300kv, on 4s each motor with a 7x6 prop should kick out around 300w power, 700grams of static thrust and a pitch speed of around 90mph.
On the scales last night all up she comes in at 1200g so she has around 1400g of thrust on tap, thats better than 1:1 power to weight ratio.... should be plenty for blatting around.
I need to sort some props and then shes being committed to air.
Sounds like you have your formula sussed out, when will it be committed ?
looking at the weather it might be sunday, if not I'm away next week so will have to wait.
My twin now named the Truck flew for the first time today, from the off I knew she felt good.. well chuffed... heres the maiden vid..
http://youtu.be/WHhiYFj9e84 (http://youtu.be/WHhiYFj9e84)
Very nice :) Pretty fast when you nail the throttle too :)
I like the sound it makes once its spun up a bit... rips the air :), check out around 1min in.
I have to say that I'm really pleased with it, she flew really solid yet very nimble with it, it'll fly slow and pull its skirt up reasonably well too, nothing got hot or over stressed even after a few minutes of being blatted around pretty hard and its good for 10-12mins on a 2200 4s.
By the way it flew I can see it'll be fine carry any extra weight too, FPV gear, bigger flight pack, airsoft rapid fire gun, bombs.... you get the idea... oh and as she handles the wind well should be good for the unlimited racing.
Flies well mate,2 sounds good to, did the dog eat it after.
;) G
ehehee nah they lose interest as soon as it stops moving, its the launch they get excited about...
I wont a race

Can we non-participants please have an update on how things are going ?
Are all the planes still in one piece ?
How many meet ups have you had ?
Who's winning ?
ehehe not a single race so far... you've seen the weather lately? :)
I never thought a small thing like the weather would stop you nutters err, enthusiasts !!
ehehe I'll get onto G (not literally) and get a race/fly day sorted, we've all got plenty of planes to crash I mean blatt around now.
I'm always ready. ;D
:run: G
I've got 2 smaller planes ready to go, but only 1 set of 5.8 gear!
I'll take some por and swap over after crashes :laugh: ^-^
