Flyingwings Falcon EVO FPV

[Billy_boy_2010]

On landing I realised my HD camera had fallen out :( the card alone was worth £50 and a similar amount for the xaiomi Yi camera :( I'm going to look for it today but doubt I will find it.

That's really bad luck :(, hope your search is successful for the cam, been there before.....

I feel like a complete idiot tbh. First time I haven't taped a camera in! What a fool!

Ah thats a sore one, must have been an expensive card! What colour of Yi do you have? Hopefully its white or yellow and should stand out! Good luck with the search!

Sandisc 64gb class 1 which I use in my gopro

Stupid really. I will buy a little 16GB for the more risky stuff!

Had a look for it but no chance really. I only have a vague idea of where I flew inverted.

Is it just me or does the falcon struggle in the wind? I will load mine up a bit more next time which will help hopefully!

It's got an AUW of around 650g, the wind will have a major impact on that.

I still manage to get a reasonable flight in even in quite windy conditions, like at Bounce the other week:

Cool video.

Just weighed mine- it's nearly 800g with a metal board cam, HD can, vector and a 2200. I'm guessing it will gain another 70g or so with a multistar 4000.

Took it for another flight today and it was really nice. Still not great in wind but getting her trimmed out with a decent CG helped for sure.

The 30A esc gets hot when inside the hatch even when she's pulling 5-10A 90% of the time! Will have to mount it outside later. Will help with the CG when I fit a bigger battery too.

She's still not flying quite right. Asymmetrical amounts of trim required on the video Tx wing. If I add a bit of weight to the Rx side will that help or just cause less predictable handling?

[Billy_boy_2010]

Is it the asymmetrical weight between the wings that's requiring the increase lift on the video Tx side?

Or the drag from the antenna?

[Brucey]

Is it balanced left/right?

5 mph faster now with go faster stripes :)

Billy, your components are too far out on the wing.

Although it looks cool to have it all separated that much, there honestly isn't that much difference in performance at the distances you'll be flying a Falcon Evo.

because your gear is so far out on the tip, that means the weight of that gear is way behind the CG point of the wing. I guarantee you'll need to put ballast in your nose if you want to keep your gear out there.

I'm not saying I'm perfect by all means, but look how I've got my EzUHF and VTX on the wing right near the centre section... I don't have any ballast up front, and on just a 2200mah 3S too, I have no tail heavy issues whatsoever and she handles perfectly fine.

remember, the further out from the balance point you place your gear, the more a small difference in weight will affect the balance. you could put only a few grams out on the wing tip and it would be like placing a much bigger weight near the fuselage.

[BlueFlyer]

And to add...

the reason it handled so poorly for you was because your HD cam fell out, this is bound to give you an unbalanced wing and I wouldn't judge the Falcon Evo's handling until you've correctly amended the CG and the control surface throws (that will sort the twitchyness)

Interesting comments Blueflyer thanks

Re the video separation distance- I think that depends on the video frequency you're using. I'm not bothered about how the plane looks but I know I have placed them behind the CG, but I wanted the CG back a bit as I'm running a metal board cam on the front, a HD cam and I want to run 4000 batteries.

At the moment I have no HD cam in the front but 63g in the front. When my new 72g cam arrives I should be nearly neutral. When the bigger batteries arrive I can put the esc out the back to keep it cooler and balance it out.

Re the balance/trim issue I'm a bit embarrassed about :D I taped a penny out underneath the wing tip to balance it before the maiden but I looked under it this morning and it was gone! Ooops! Anyway another penny added and its trimmed much better now thanks :)

I figured about the sudden CG change and handling was down to a lost camera mid flight lol ;D

Your plane really looks nice. Maybe I will add a bit more colour to it.

What would people recommend motor wise? Looking for something decent quality and will be running on 4S 3000mah batteries. Not looking for a speed monster, but a mid way point of speed and efficiency. Thinking probably somewhere around 1000kv with an 8x4 or 8x6 prop should do it. Preferably one with a decent shaft and prop mount and not the stupid collet style ones. Can never seem to balance those properly.

Might just get a sunnysky 2212 980kv actually, got them on my multis and been happy with them!

I'm using this motor 

http://rctimer.com/product-117.html

which comes with the eco power system 

200W and 50g.

It's pretty good tbh. Fast enough to punch through wind and pretty efficient but it wont be a super beast. She pulls 15 -16A at full throttle but will cruise at around 5A. A 4s system would be nice I expect. Maybe aim for 250-300W?

The battery bay isn't huge. You could probably fit a 2200 4s in there but, unless you can find something a similar length you won't get much bigger without mods to the battery bay. Having said that I have a full autopilot in mine and she will carry a board cam and HD.  It has the potential to become my go to wing with a bit more tweaking.

Don't suppose this is much help but

[iPeel]

I run mine with a 980Kv on 4S turning an 8x8 prop. It flies nicely but on an aggressive climb out you need full throttle. Probably more like 1200Kv is a good bet if you want a bit of headroom, mine will do 100Km/h on the flat though.

Battery-wise if you're talking about a 4S 3300Mah nano-tech then it won't fit in the bay, the battery goes across the width of the bay. It will just take a 4000Mah Multistar though with just a bit of teasing away from the front of the battery bay and I found it balances out quite well but I don't run a high def camera up front. You wouldn't need that battery though unless you're planning on doing serious distance, I normally fly on an 1800Mah and get half an hour of gentle flight out of that.

[Billy_boy_2010]

interesting ipeel. you must be really nursing it to get half an hour. I think im closer to 15-20 mins. Mine is balancing with a 2200 3s with a HD cam and heavy board cam on the front. I think a 4000 will make it quite nose heavy but i will put the esc much further back which will hopefully help a bit.
