The slip of paper I got with mine says the CoG is 180mm from the nose which is a complete lie :laugh:

What should the CoG be then Steve?
Title: Re: Flywings falcon build
Post by: FPVSteve on July 24, 2013, 06:53:06 PM
I've not figured that out yet, I plan on doing some more research tonight. By research I mean strapping lipos to the nose until it flies acceptably :D

Does it not fly well at all then with the recommended CoG? Or is it just twitchy?
Title: Re: Flywings falcon build
Post by: FPVSteve on July 24, 2013, 09:50:56 PM
Well, mine flies really nicely with the CoG 195mm back from the  tip of the nose and a 2200mAh + 1000mAh 3 cell up front for video.

Now I need to get some 3m spray and cover the leading edges.

Oh so 180mm is too noise heavy?
Title: Re: Flywings falcon build
Post by: FPVSteve on July 24, 2013, 10:30:45 PM
180mm = tail heavy, on mine anyway - I guess it depends where you cut things.

I simply used hotglue and then reinforced the centre wing join with some tape. In fact I've used smeared hot glue for the elevon hinges too, works a treat.

I don't like UHU - I've found on some foams if you put it on too thick it starts to make the foam spongy.

Yo,

Hot glue is great, its quick and it does not set rock hard, so retains some flexibility like the foam.

CofG is 180mm for stable flight, 195mm would be ok but just on the limit, may spiral out in slow tight turns.

The smaller the number the more nose heavy it is, ie 180mm is more nose heavy than 195mm

Mucho new improvements coming

Just don't use tape to secure your wiring loom - the foam is oily ....

Have to say when it does make it into the air it flies really really nicely - I do need a power upgrade though, there's something wrong with the motor I'm using for sure so this is a good excuse to get something beasty on it :D

That "flight" was with a 2200mAh + 1000mAh battery up front.

Looks interesting.

Slowly!
Started cutting holes for the various bits. Just don't have the time at the moment.

bloody hell steve that went down like a tone of bricks :/
mine lauches beautifully well you have seen for yourself :)

Yea so does mine normally mate, but not when the wires go through the motor :laugh:

Actually on further extension, only damage is to a servo extension cable .. fixed :D

I've got the revolution on it. It's got a built in UHF tx/rx for telemetry and rc control, so that will be my rx for the rc.

I've bought a stand alone oplink too that takes the ppm stream in from the trainer port. Means I use that instead of the ezUHF for the falcon
Title: Re: Flywings falcon build

I found adding nose weight made it fly quite a bit faster - a nice wing for sure.

Nice! What powerplant are you running on that??
Title: Re: Flywings falcon build
Post by: Brucey on July 28, 2013, 06:16:52 PM
That goes really well. Must get mine finished!
Title: Re: Flywings falcon build
Post by: FPVSteve on July 28, 2013, 07:29:46 PM
Mine wasn't as quick as that although I did have the VTX and extra  lipo onboard when I maidened it - only a flight cam to add but I think I might pick up one of those motors as I'm using an old AXN one that to be honest has seen better days.

Hi Andy,

You maybe exceeding the airframe speed a bit, try some laminating film, down the leading edge.

the motor your using is really only good for a 6x4 apc type, if you want to run an 8x6 then go down to 1400kv.

I use the same motor (2200kv) with a 6x4 and get really good flight time and decent performance.

Like the mod tho, has it reduced any waggle ?

Cheers rob

Good Luck!

Yep, interested to see this because I'm wondering whether I should add some tight tape support around the wings crossing across the airframe to stiffen it up a bit - it does feel a bit floppy.

It might feel floppy guys but I have certainly had no problems as standard :)

Yea but you've not FPVed it either, if you get a bit of lick on it might be enough to make things come loose if it starts to flex...

Can't you just back off the throttle a bit you hoodlum?? :laugh:

Looks good Andy. This is how far mine has got.

Post by: Brucey on August 01, 2013, 08:22:13 PM
Yep, it's a revolution. I've still got the battery to go on, and I have tried to plan it all out to avoid lead! But who knows!
I've stuck a load of leds on it so it's lit up like a Christmas tree. Hoping to get some ufo sightings;D

No idea. I'm still waiting for some strobes! Not much to do, just finding the time for the odds and sods.

Looks good Andy. You should of got brave and put the goggles on!

Afraid not, the weather don't look to great either. Maybe next weekend.

Looks good, hope the OSD performs well
