Ok 2 more flight on it afrer some modification. UAT runs good now. Marcel did another flight on it and everything went good, with a fair front wind he didnt use the air speed brake and the plane landed quit well. Next shot was MY turn on the stick...I was quit nervous but i did it ok. I was uncomftable with Marcel's setup (40% expo on everything) and i flew it kind of slow. Flying it slow give us the chance too see that it have tendency to 'Deutch rolling' or 'Deutch coupling' (dont remember the exact term

) at slow speed. After the landing i saw on my 10X that i didnt put any differential and that coud be a the key. I setted it up at 35% differential and 25% expo everywere but i didnt fly it. I will try it tomorrow with that setup.
How munch differential do u use on your Stingray??
