Hey guys, I just started flying a Hanger 9 showtime 90 4d, and am really enjoying it. It would be the perfect plane for me except for if I do a "high speed" pass over the runway just above half throttle, the ailerons flutter like crazy. Is this a characteristic of a 3d plane with large control surfaces that cannot be avoided? Would higher torque aileron servos be able to reduce this? I do have the gap sealed on them, btw. I'm running a Saito 1.25 on it with a 16x6 APC and was thinking maybe some of this is from engine fibration at high rpm's. Just a thought, this is my first four stroke. Maybe I should try a 16x4w to prevent overspeed and provide better hovering? Sorry for rambling, lol. I just need some advice from more experienced folks... Thanks in advance
