Title: Maiden and failed launches of my Falcon EVO
Post by: AdamG on January 18, 2016, 04:43:05 PM
The maiden took place Saturday. Firstly I hit the deck twice before getting it in the air (included in the vid). I had some even worse attempts which were more like crashes (upside down etc) but the impact on the GoPro turned it off and lost the recording :(

So last night i'm looking at it and I realise that the prop is on the wrong way round! does this make a huge difference to the amount of thrust? I assume it makes quite a difference due to the scoop design when spinning the right way  :+

AP was behaving well in PA (stabalised) but RTH was losing altitude too quick when banking. I've reduced the gain and angle but forgot to test on the second flight as I was just enjoying flying.

A Reversed prop would probably lose 60 to 80% of thrust depending on the design of the prop causing cavitation.

This probably explains why I had trouble launching it! Even on 100% throttle!

Its an APC 6 x 4

Apart from the severe lack of power it flew pretty well and no bots fell off which has to be a positive :)

Haha yeah it went well for wing that was put together a bit backwards  :laugh:I did think it wasn't as quick as i expected  :laugh:

Ordered 2 4amp multistar's to upgrade from the 2.2amp I'm using now. Looking forward to trying it again with the prop on the right way  :D

lol at the backwards prop...oops... we've all been there.

is the motor a 2200kv?

I managed good flight times with a 1400kv motor and a 8x4 APC type prop on my falcon Evo.

A new lesson every time i fly  :P

Yeah its a 2200v with the 6x4, what flying wings label as the 'sport' power system. I'm tempted to buy a 1400v with an 8x4 and its a simple 4 screws to swap between sport and eco  :D I think the motors a pretty cheap too!

I had to add a bit of weight in the battery bay to balance the wing... I think going from the 2.2 to the 4amp battery It will balance perfectly without the weights.

Always make the the numbers (i.e. 6x4) face the front of the prop :)

These are what I use.

She will even carry two of the 4000s and an autopilot at a bit of a push. Launching is tougher (although Im using the 1400 kv motor) and the stall speed is higher but it makes for super long flight times. Too long realy it got a bit boring so I normally fly with just 1.

I really cannot fit a second one in there, I've cut out extra space to fit my AP and my gear bay is rammed so full! But like you say, I think 4000 will give enough time for a fun flight. You must be up for a while on just the one if Blue can manage 20 mins on a 2200. What flight times are you achieving?

I don't pay a lot of attention to flight times- 2 setups could potentially cover the same distance with the same battery usage with one flying for 20 mins and another slower model flying for 25-30 mins. I get bored after a while anyway and concentration starts to fade. But I know I covered at least 28km total distance with around 5000-5500mah of battery in the falcon. I think it was cruising at around 6-7A from memory but I forget in truth. Had I spent more time tuning it and tweaking it I would imagine I could have reduced the cruise current a fair amount.

I put my second multistar right at the back on top of the autopilot- it's almost on the CG here so doesn't throw it off much. The hatch still just about shuts when taped up. And I moved the esc to the very back.

If you're happy with the performance of a 4000 stick with it. I do most of the time. But if you had a real range target in mind- and based on your skywalker I suspect you may do (the falcon isn't a bashing wing) putting a second in there is an option. Over the summer I will see what sort of distance I can cover with the 2x 4000s. I reckon 40km is reasonable. What's the total range of your fully laden laden skywalker?

The only real disadvantage is the stall speed goes up a fair bit (and it's not as fun or playful)- which in turn means you don't have the option of really throttling back and enjoying the view/object you're flying around. The broad speed envelope of wings really appeals to me- but if you load the falcon up you do lose this a little.

I actually don't really have any interest in long range flight with this one. I'm just flying it on 5.8 skew to skew (might occasionally use a 3 turn helical on the goggles. I wanted it to be an easy pick up and fly plane... Skywalker requires assembling and a lot of kit to go with it. I don't intend on taking big risks with it like you would a basher but I do want to fly it low and fast/ around obstacles.

My Skywalker's longest flight so far covered just over 50km. I'm sure I could squeeze more out of it if i was really trying for economy. Thats with 10a 4S on board.

Ha cheers for the sub  ;D I actually moved from B'ham to Dublin in August so currently out of the UK, but only really plan on being here for 1 year.

Yeah that third launch was so close to being another fail! maybe when I put the prop on the right way I won't have these troubles  :-[ :-[

Fair enough mate.

Just be aware that the falcon is such a flexible wing, and requires almost no fiddling at the field- it may become your go to plane 85% of the time- at which point you will want to broaden its abilities even further. Then that figure will become 95% ;)

Keep the Falcon as a low & fast basher and get a Venturi for long range stealth missions mate.

A 6 x 4 Prop on a wing of this size..?...Surely not..?.....Can't imagine why they would call it a "Sport" set-up either, it will just make a lot of noise and not really go very fast......An 8 x 5 or 8 x 6 sounds more like it with a 1200kv motor maybe.
  Surprised it flew at all with the prop on backwards....lol...Says a lot for the plane though....I like this Falcon wing, but don't you think they are a bit pricey?

:terrific:

Title: Re: Maiden and failed launches of my Falcon EVO
Post by: BlueFlyer on January 20, 2016, 11:27:36 PM
a 6x4 prop with 2200kv motor would normally be a "sport" setup for a wing of this size... IF it didn't have all the FPV gubbins inside...

a tek sumo is a little bit smaller than this and a 2200kv/6x4 combo is epic for a LOS sporty flyer

once you start putting batteries bigger than 2200mah and extra gear like GoPros, FPV stuff and an AP... you really need the thrust you get from a bigger prop

Although the 2200kv/6x4 combo works... I would still recommend the 1400kv/8x5 setup... it still goes vertical... trust me :)

Post by: AdamG on January 20, 2016, 11:39:59 PM
You can get a decent 1200v motor for like £10 so I might just buy one and switch it in the field depending on how I want to fly. Really looking forward to getting back out and having another go now. Surprisingly the 4000mah multistar is only about 50g heavier than the 2200 turnigy. I think the aircraft will weigh the same with the 4000 after i take the extra weights out of the battery bay.

As for the 220v 6x4 combo, I will give my opinion once I've given it a fair trail. It was cruising along at 40mph with the prop on backwards  :P

Neil I like the Venturi but don't have space in my apartment for a 5th FPV aircraft  :laugh:

Tim have you built one of these recently too?
Title: Re: Maiden and failed launches of my Falcon EVO
Post by: Gundummy on January 21, 2016, 12:04:28 AM
Yep... Falcon Evo build...

Just managed to get everything talking to each other as of today,  RVOSD, 1250Kv x 10" prop and 2 x 5000mah 3s on 1.3g with ezuhf. (thats the bench set up any way  ;D )

Mine was originally getting the Ruby AP installed but that got side swiped moons ago.  (Probably opt for the EVO 2 with Ruby now......once i've got everything tuned and tested)

Reason for the delay is swapping all my frequencies around...

My Falcon AUW is currently 980g. That's with a bit of weight added at the front to balance it.

Yeah mine should be nice and level with the 4000 too. Switching from the 2200 to the 4000 only increased my AUW by 50g because I had to add a little weight into the battery bay with the 2.2 for COG.

So that motor is getting you 20mins with the 4000? I was looking at this motor for efficient flights:

Cheers

Post by: Bertie on January 28, 2016, 06:32:54 PM
I picked up the motor I posted the link to based on a friends recommendation. I have it with the shaft end going into the foam (made a hole) and the prop on the bolt on adapter. I don't get any jello at all and the throttle control is nice and smooth. The 2200kv motor I had gave me about 10 minutes of fast flight on one of the cheap hobby king orange motors, that motor gave up the magic smoke and died but what do you expect for £6!

btw what settings do you have in you tornado (pitch and gain)?

On stock settings PA was fine but on RTH when it banked it lost a lot of altitude. I lowered the gains and the angles but haven't had chance to test these settings yet. Think it will require a bit of trial and error to get it right, let me know your settings if you manage to get success :D
Title: Re: Maiden and failed launches of my Falcon EVO
Post by: Bertie on February 01, 2016, 11:28:49 AM
I cranked the gains up to 100% as on PA mode it would bob up and down all the time. The only problem I have is in PA mode its very unresponsive to stick inputs.

I`ve seen a few videos of Storm osds heading into the ground on RTH


I`ve never had this problem but it may be worth checking out for you.
Title: Re: Maiden and failed launches of my Falcon EVO
Post by: AdamG on February 02, 2016, 08:32:21 PM

Thats a buggered storm or its not been configured correctly. Take a look at the pitch and roll values, its on like +25 roll when its level. When it dives for the floor the pitch is on +10 so it thinks its heading up.

I would think increasing the gain on yours might make it worse! try lowering it and see if its any better. No idea when the weather will allow me to fly this again for testing :(

Post by: AdamG on February 11, 2016, 10:43:26 AM
I managed to get a flight in yesterday and test the Tornado briefly. So PA is still working fine.

RTH: On the maiden it banked to hard and was losing altitude very quickly, definitely would have crashed if i hadn't taken over. I lowered the gain and lowered the allowed roll angle. This time it didn't lose altitude, it flew nice and smoothly, but it wasn't turning enough to circle me and slowly started heading away from me. Will revise settings and have another go and let you know the results.

I think around 100m for RTH. Just need to slowly adjust the roll gain and angle until it works i think
