Default Jet Legend F22 neutral elevator setting?

Hello Gents,
Question for those of you out there that have owned or flown the JL F22. I just finished mine up and getting it ready for maiden. I have read several threads that have indicated that the elevator neutral should be set at 10mm up trim for straight and level flight. Just wondering if this is correct? My CG is set at 210mm. I would prefer to not have any major pitch surprises on the maiden if at all possible. Thanks for your help. Jon

Barry Hou (from KingTech) has had a couple of these and been very successful, he should be able to help you out if he sees this. If not, try sending him a PM.

HI Jon,

It is true that some uptrim is required for level flight. I have a cg of 210 on mine as well and the elevators are level 3mm above the fuselage seam line.

Hope that helps.

regards

Hello Jon,

I have 10mm up as well with the cg set at 185mm, gear down / empty tanks.
I find it very pitch sensitive at 210. You can fly it at 210 with reduced throw or with a gyro.

Good luck with the maiden, it is one of the best airframe available

regards
Florent
