Hi guys
I have the AVTX5.8 Transmitter 800mW and fat shark goggles and I need OSD and Stabilization system . What is your opinion about this combination?

you can see my 31AP thread here..

http://www.rcgroups.com/forums/showt...575919&page=76

I love my FY products... yes there are some downfalls but so far they are the easiest to set up and they just work.

If you expect military grade performance then you are gonna have to spend lots more money

What is neutral setting for elevons to start with, 0 or some mm up?
Is hand launching better with more deflection or same like those for level flight?

I had a flying wing, and it needed 5mm up elevons just to start with,
even more for launch, but it had much higher wingloading than x8 and smaller thrust to weight ratio (smaller prop in goal of getting higher speed)

My X8 needs no UP clicks of elevator for launch. I throw it at full throttle and a bit of above level inclination, with the same trim as the last flight it had.
Now, having said that, your first launch could be tricky because you don't really know if the plane is trimmed for normal flight. Also keep in mind that the warpage that gives an upsweep on the rear fuse wing root is different for every plane. If you leave it as is, trim will be different than if you use something to line the wing root with the part of the wing it meets. On mine, the warp is slightly different on one side than it is on the other, so one elevon has more down defection than the other just to make it fly level. It looks goofy but the plane flies just great.

PS. As with you, my other planes are different. My Funjet Ultra needs about 12 clicks of UP trim for launch and my V70 Zephyr needs 6 clicks of UP. And my flying Pterodactyl needs nothing.

Beautifully designed and made DT. makes mine look like scrap metal.
What is your kg pull? and the AUW of the X8?
Mine will be shy of 5kg so that + the cradle I figure I need close to 35kg of pull on the bands (6 loops @ 1m perimeter)
Again very nice engineering...your power toys are way better than mine.
