Title: Multiplex Fox FPV bulid
Post by: g.collins on June 20, 2011, 01:24:42 AM
Hi all
this weekend I disided to build a quick FPV, to have a break from my big project.

first of the platform, I went for the Fox by Multiplex, a small free flight glider, weighing in at 45g.

(http://s4.postimage.org/2aoy4yack/Fox.jpg) (http://postimage.org/image/2aoy4yack/)

remove the 9g Bering from beneath the canopy, taking the plane down to 36g

(http://s4.postimage.org/2apd0sesk/9g_wate.jpg) (http://postimage.org/image/2apd0sesk/)

cut a hole in the wing for the aileron servo

(http://s4.postimage.org/2apmy0hr8/wing_servo.jpg) (http://postimage.org/image/2apmy0hr8/)

slid the wing in and mark around the servo to cut a hole for the servo to fit

(http://s4.postimage.org/2aq54xb6s/markin_fuz.jpg) (http://postimage.org/image/2aq54xb6s/)

cut a compartment in the fuselage for the rc kit


(http://s4.postimage.org/2aqdem1no/control_conpartment.jpg) (http://postimage.org/image/2aqdem1no/)

fit the servo for the elevator and feed the wires to the fuselage compartment

(http://s4.postimage.org/2aqtxzilg/elivater_servo.jpg) (http://postimage.org/image/2aqtxzilg/)

mark out the wings for ailerons

(http://s4.postimage.org/2arkel2hw/mark_alerons.jpg) (http://postimage.org/image/2arkel2hw/)

stiffen the wing with a carbon tube

(http://s4.postimage.org/2asftsnvo/wing_stifner.jpg) (http://postimage.org/image/2asftsnvo/)

I laser ed out some small servo horns from ABS plastic

(http://s1.postimage.org/1fb0q9rgk/servo_horns.jpg) (http://postimage.org/image/1fb0q9rgk/)

then fitted them to the wings

(http://s1.postimage.org/1fbanhuf8/aloron_horns.jpg) (http://postimage.org/image/1fbanhuf8/)

same proses for the elevator tail wing, I used a small length of piano wire to connect the to elevator flaps

(http://s1.postimage.org/1fc143ebo/elivater_fitting_stiffner.jpg) (http://postimage.org/image/1fc143ebo/)

a length of piano wire is used for controlling the elevator, ther is a small loop in the wire so I can make fin adjustment to the trim if necessary

(http://s1.postimage.org/1fescc7yc/elivater_fitting.jpg) (http://postimage.org/image/1fescc7yc/)

I have used a spectrum 6 Chanel receiver, that ways in at 2g, I have hollowed out the front of the fuselage for the flight battery

(http://s1.postimage.org/1ff8vpow4/rc_control.jpg) (http://postimage.org/image/1ff8vpow4/)

the motor mount is laser cut from 3mm plywood, and the motor is an AP05 giving 100+ grams of thrust from a 2 cell lipo

(http://s1.postimage.org/1ffudp7b8/motor_mount_esc.jpg) (http://postimage.org/image/1ffudp7b8/)

the fpv kit is ran from a single cell and weighs in at 11g withe the battery

(http://s2.postimage.org/1pkwywk10/fpv_kit.jpg) (http://postimage.org/image/1pkwywk10/)

I fitted a mini servo to rotate the camera and cut a slot in the top of the canopy to holed the video transmitter, all the wires are fed to the canopy core



I have fitted the battery for running, the FPV kit in the side of the canopy for quick change

(http://s2.postimage.org/1pogbaa1w/comara_battery_mount.jpg) (http://postimage.org/image/1pogbaa1w/)

that's it, all done, the complete flying weight is exactly 100g, I will test it the next time the wined behaves

(http://s2.postimage.org/1pp54chgk/finished_fox_fpv.jpg) (http://postimage.org/image/1pp54chgk/)

Cool Gordon !

I made a 'big wing' Fox (cut up part of a second wing and added it to the original).
They really like to fly fast!

ChancesAU has made several:

I don't FPV mine but it's fun to fly.

great vid Nigel, tuff little things aren't they.
Do you no where the c/g is on this plane, as a hand glider, its ruffly in the middle of the wing, I have aimed for it 1/3 back from the leading edge, I can change this with the flight pack.
I was a little concerned with a wing mounted motor, mossed of the conversions I have looked at on you tube, have fitted them to the front of the fuselage, the motor has got some push to it, when I holed it and power it up it wants to dive into a forward roll, I'm expect wont's some air is passing over the wings giving lift it will be fine.
I built it to have a short rang FPV that I can yous in the parks her in London.
Longer rang I will have to travel outside the city, I wont to be able to fit this in a case, and jump on the tube with it.
it will be a great little bird to leave in the boot of the car, for FPV emergences.

Hi guys, can you advise
I have been looking at more examples of this conversation and here a lot of talk about thrust angle, on wing mounted versions,  place motor angled down, do they mean the motor facing the sky and blowing down or the motor tilting forward and the air blowing up, I would hate for it to nos dive or flip on its maiden and damage the video gear, the video transmitter comes from Turkey and would tack some time to replace..
regards G
Title: Re: Multiplex Fox FPV bulid
Post by: Pasty on June 20, 2011, 05:05:59 PM
looking at most other high motor pushers they have the air blowing up, so the motor shaft is angled up.

Great little build their Gordon!

Can't wait to see this pocket rocket go  :)

cheers guys,

thanks Steve, I looked at more of the same builds and thay all have the motor set the way you suggest, so I have adjusted the motor accordingly.

I no what you mean Dave, good idea, I think I will tack of the canopy, and stick some cones on to mack up the weight. It was a lot of fun converting it, I recommend giving it a go, this is a short rang 2.4ghz version, if it goes well I may build a 35 mhz version, with a bit more reach.

My CG is at 33mm from leading edge.

500mAh LiPo lasts 10 mins.

Infectious little boogers!

Mine is up for sale, including the Tx as the Rx is buried inside the fuse.
Sean (sheep600fx) has got first dibs on it...(Sean doesn't want it, so it's up for grabs)


This is the best FoxFPV vid, I reckon

Brill video Nigel
more help and advice needed
Well she had her maden this morning, before I went I adjusted the motor to face down, as suggested and removed the camera pod.
I have videoed it, but it is on my gopro and needs to me comprised before I send it.
I powered it up and launched it, and it went great for 2 seconds, the C/G seemed fine, but I forgot to turn on the video, so I bought it strait down, before I tried any maneuvers,
when I tried again I launched it at just over half throttle, it was all over the place and crashed, I tried it at full throttle and gave it a good hared chuck, and away she went, and is pretty stable, it seems to wont to fly at full throttle, els it misbehaves, it will fly once its going at 3/4 throttle but it seems a bit unpredictable,
when I dropped the throttle to land it glides beautiful, very strang. it also seems to bee a little underpowered for the amount of thrust to weight reshow, perhaps the motor is angel two much, I will experiment when I can.
over all I'm pretty pleased with the first tests, any suggestions.
thanks Gordon

It's like I said, they like/must be flown fast else they tend to stall.
They are a bit twitchy at the best of times, but mine is entirely predictable.

I did several tweaks to mine, including reducing the angle of attack of the wing and tailplane, and making the big wings.

On my tail, I shaved a bit off the fuselage foam where the tail sits, tapering from a couple of mm at the leading edge to nothing at the trailing edge, use a really sharp blade for this.
Removed it from the bottom and glued it back on the top !!

OK hear is the madden test flight, first thing this morning, thanks to all that gave advice on this little bird, much appreciated, it flies pretty good on full throttle, some dodgy landings at first, over all it looks promising, FPV flight hopefully at the weekend at the FPV meeting.
looking forward to that, train all booked. :D

Good maiden Gordon.
Definitely likes to fly fast and need to keep some speed up in a turn or it just drops a wing and spirals to the ground.

Try a big wing version sometime as mine will fly slower than that, no probs.

Great fun little birds and you just can't hurt them !

Maybe I'll try my spare fuze with a set of homebrew wings and pusher motor/prop....

The plane is a little beaut, I took it out again tonight in the wind, I wanted to see what it would cope with, it was shaking that ass, but was good fun.
Ow, I was wearing soggy Vans, I watched the hole vid to see what you meant, couldn't see my feet, lol or are you talking about my Cornish bounce. :laugh:

Thanks to all the positive response, for this little bird, it has been FPV flown by a couple of FPV pilots from this forum, at this weekends meeting, and myself, and today I gave it a go up on the Black Heath hear in London, flying with the big kite surfers, bit windy, but its great fun, I have to soars some sort of DVR to record the flits, as soon as I do I will posed one.

I have enjoyed making this model so much, I think its Time for the mark 2, its the Mint Fox, I have 2 of these so I'm going to mack a long wing extension model, I'm also thinking of linking the right aileron with the right elevator and vise versa, and mix the channels, this will allow me to break it dowen to fit it into a small carry case.
I'm also going for a longer rang RC setup, with some 350mah batteries instead of the 180mah that I'm using, ther only 3g heavier.

That looks awesome! Cant wait to see how it turns out, are you using a bigger motor or sticking with the same one.
Title: Re: Multiplex Fox FPV bulid
Post by: Sheldon Holy on June 30, 2011, 11:06:27 AM
Gordon,

From my experience with linked ailerons-elevators on a few models, it is a bad idea 99% of the time.

I'd just stick with rudder/elevator for a plane like this. I had a Fox converted to RC a while ago, with just rudder/elevator and it was a glider which I would strap to the belly of my Uno-Wot and release up high then get someone else to pilot it down.

Great fun!
Title: Re: Multiplex Fox FPV bulid
Post by: g.collins on June 30, 2011, 11:28:17 AM
I have bought the same motor an AP05 and ESC, power to weight it is impressive, I'm not looking for vertical clime, any moor power and it will shorten the flight duration.

Post by: g.collins on June 30, 2011, 11:59:27 AM
Thanks Sheldon
I fined that I get beter response and it suits my way of flying beter when I use aileron and elevator, plus I'm toying with the idea of fitting a micro gyro to the ailerons to see if it will stabilize it a bit, I recon its worth a go if it doesn't add to much weight.
Title: Re: Multiplex Fox FPV bulid

I had ailerons on my RC fox (glider only), they worked a treat.
Title: Re: Multiplex Fox FPV bulid
Post by: g.collins on July 01, 2011, 11:31:38 AM
Ha pasty
yes I'm well pleased with the response of the mark 1, so if it ant broke, this one is only going to have longer wings, so it can take the small GPS I have ordered and a 350mah battery, longer rang on this one
Did you have the baby Multiplex Fox like mine, or something bigger.

Title: Re: Multiplex Fox FPV bulid
Post by: Pasty on July 01, 2011, 12:11:02 PM
The baby fox with slimline micro servos in the wings and an all moving stabiliser... it went really well but I needed the servos for a new project so she has been moth balled (slung under the workbench never to be seen again prolly) :)

Hi Guys, I have disided to finish the Long winged Mint Fox, I have made a few changes to this one, apart from the longer wings, I have fitted a longer rang RC risever, its still a park reserve but I should get a grater rang, I have also fitted a tiny Gyro, to the ailerons, to see if it will keep it stable in the wined, I took it out tonight and test flow it, unfortunately it looked like it was going to rain, so I didn't tack the video camera.
verdict, brilliant, its so much smother than the first one, and flies at a slower speed at lower Reeves, I set the timer at 10 mins, and still Had power left, I will get the video kit on this weekend, I have made a clover antenna for the video transmitter, I have boult a Skew Planar Wheel Antenna from Simon @ www.firstpersonview.co.uk (http://www.firstpersonview.co.uk), unfortunately my 5.8 receiver has a mail connector, and so has the antenna, I'm hoping that I can get an adapter.
stay tuned for the first FPV flight, I cant wait.

It tacks a few gos to discover the best way to fly thes plans, I discovered the best way to hand launch them, just the other day, it likes to be launched real fast.

Way more sensitive than anything else i've flown, I just have to lat go of it on full throtle and its off :P
Can;t use full throt for more than 25-30~ secs though, or the ESC overheats and disables the motor, interesting experience finding that out :+
I reckon mine would be smoother with a gyro, but then again i have been flying in wind only...

I haven;t used that motor, but have you considered the F1818, very neat little motor, High, KV, but it might eat your lipos though...

Post by: lordchris on September 29, 2011, 09:15:07 PM
if i keep the weight down, with the ap05 i could punch the fox up high and then cruise. hopefully give me ok flight times.

Nice one Chris, I have posted the motor mount, and control horns for you today, I have the correct amount of angel on the mount so just mount it the same as mine, following the contours of the plane and you will be fine.

Hello I recently built up a fox as amini pylon racer sort of thing...i didnt really like the way it flew UNTIL i lessened the angle of attack ie lowered the leading edge of the wing only a couple of mm. needed ".it cleaned it up" aerodynamically speaking . This thing is really a chuck glider but if your gonna add power and rc etc think you'll find this makes a big differance. speed will remain speed instead of the wing angle turning it into lift all the time
have fun

Looks good, Might have to buy an orange one. Or maybe I could have a Tri fox, Orange green and pink :D
@Snoops
Pics, sounds like an interesting mod, but doesn;t it increase the stal speed?

Awesome thanks G!
tonight I'm going to install some servos.
il also be ordering my motor and esc.
I want to run this little fpv'er on 2cell 210mah packs
the ones I fly my beast on. Do I need to select the
esc with the diode? that says 2cell? I'm guessing so.
the next question would be....
what connector do I need for the esc to my Rx?
Its some kind of Jst connector but I'm not sure.

not sure about this wing mod idea. I'd like to see some pics also.

I compared my fox the the mosquito. it actualy looks like
I have less wing area and more weight!

I yous a red Jst connector, and those batteries are fine, you should get 10 Min's fly time, if you keep the weight down, my short wing fox is 100g, I run HYPERION G3 2 sell batteries.
I also fly the beast, and these batteries are good for that as well.

I modified my Fox wing attack angle as well - definitely makes it more flyable IMHO.

I cut a wedge shaped bit from the lower side of the fuselage wing cutout - tapering from nothing to a couple of mm at the front (use a brand new Stanley knife blade on it's own, not in the handle/holder) and then UHU glued the wedge bit back on the top edge - simples!!

Hello again G
quick question. What prop would you suggest with that AP05? throwing together the last order of bits tonight :D
cheers Chris


ps. The motor mount and control horns arrive today! thanks very much! they are top quality!

Iv been toying with the idea of building a nano pan and tilt set up with 2tiny 1.7gram servos! but think I will a little while. I want to build a large 2nd wing
to make a really floaty fox! then il build a pan/tilt for it. I also have a tiny compass to mount as a little navigation aid. not sure if it's over kill or not needed but maybe a heading will help.

Everything has arrived! :D except the weird UMX battery plug. which has to come from the states!
the reason for using the umx plug is because i dont want every type of lipo out there...

everything is made up ready to go.
got my ailerons cut and fitted.
got the elevator cut and fitted.
Body is chopped and hollowed where need be.
about to make the control rods.

things still to do...
solder everything!!! which is a job for my OCD leccy friend. that way it will be neat.
install my micro fpv gear (at said ocd leccy friends)
wait for the new patch antenna to arrive

Yeah - it's typical for the US I'm afraid. 

When I lived in South London, I never had a problem... must be the volume of mail they have in each area perhaps which allows a higher number to be stopped and reviewed at clearance through customs...  HK is never a problem, but US, I usualy dont bother with.

top tip guys. If you order from HobbyKing in the future DONT chose the option that says "Royal Mail Parcel" even if it's a little bit cheaper. That's when parcel force get their mucky little mits on your gear and charge you for the privilidge.

I had a charge from customs for £8 on my 9X(and other stuff) from HobbyKing, but I had to pay parcel force another £8 on top for their "admin fees".

Always choose EMS or whatever the cheapest is, as long as it's not "Royal Mail Parcel"

My carrot long wing version is weighing in at an enormous 120 gram without motor and esc.

the culprits are Rx 35meg full range at 14 gram, and 350mah 2s battery at 22gram, Think I should dump these or what?

Hera are a few of the picture from the FoxHawk build, in this picture I removed the canopy and cut away the poly hump that holds the canopy on.

(http://i1217.photobucket.com/albums/dd397/itsalivecollins/FH1.jpg)

then I hollowed out under the canopy, to holed a 2 or 3 cell 330mah lipo

(http://i1217.photobucket.com/albums/dd397/itsalivecollins/FH2.jpg)

then I removed a section of fome from the base of the fuselage, and hollowed it out, to fit the RC and a giro, that hasn't arrived yet, it also meets up with the battery compartment, this will be how the battery is fitted, when the canopy is fixed back in place.

(http://i1217.photobucket.com/albums/dd397/itsalivecollins/FH3.jpg)

I fitted one of my motor mounts, this one is a upgraded version, its a little bit stronger, and I mounted a Turnigy 2211-2300 motor

(http://i1217.photobucket.com/albums/dd397/itsalivecollins/FH4.jpg)

I then cut a hole just under the trailing edge of the wing for the mini servo

(http://i1217.photobucket.com/albums/dd397/itsalivecollins/FH5.jpg)

on the canopy I have a small 5.8 VTX and a mini wide angel 5v camera, that are both powered by a 160mah lipo, that slides in a hole in the side of the canape, I have fitted Velcro on top of the flight camera so that I can mount my HD key camera.

(http://i1217.photobucket.com/albums/dd397/itsalivecollins/FH6.jpg)

hear it is finished.

(http://i1217.photobucket.com/albums/dd397/itsalivecollins/FoxHawk.jpg)

and hear is its maiden, as you will hear in the video, there's a bit of beeping for trimming it up, but it flies great, i'm really happy with it.
I also FPV flow it, strait after and it was great.
