I believe I've tried everything.......When i'm at a hover the tail is wagging back and forth.......not enough wag to prevent me from hovering though. I have adjusted my gain back and forth on my DX7 and flew with full batts to make sure the ESC is working fine, but it still waggs. I noticed that the tail boom looks very slightly bent to the left when looking from the rear but not very noticible unless you really look at it. The other thing I also did was opened my DX7 and played with the notch bar on the throttle/yaw stick(left stick), when you move the stick up and down there is notches in the feel of the stick, I flipped it around to the smooth side, and loosened it up. Maybe this is the problem? Over all the tail waggs and seems a bit glitchy in the throttle and acceceleration..... any ideas would be helpfull. Thanks in advance!
