These servos are in my H-9 Sukhoi. I have two servos per ailoron. I was wondering if one servo is fighting the other or something. I have notice my left ailoron wants to wiggle a bit. But I heard digital servos do that to find the center. I just know they are Futaba Digitals. I dont know the number. I will check the next time I am out at the barn. Now I do a lot of moving in the air. Like the rolling harriers knifeedge flight. Basically I am never flying level. Also I will check what mah battery I have.
