hey guys , has this ever happed to you ? I have a slow pitch ossoliation front to back of about once every 2 seconds , and its fairly severe say +,- 5 degrees. it acts like a rocking chair , and I don't know whats causeing it. the behavior started after a fairly severe crash , tho I have replaces all the damaged parts I am aware of. there is no side to side ( roll ) or yaw cycles , and the heli is fairly controable other wise but its obviously far from stable . the blade tracking seems good , it may not be perfect but its close , hard to tell with the black blades . swash plate is level . and the run out on the main gear , shaft and fly bar all seem ok. my current suspects , are fly bar paddles , ( one got a bit chewed up on the crash but its not real bad , just a bit rough on the leading edge ) or perhaps the adjustable links from fly bar to blades , maybe I am a turn wrong from where they are soposed to be ? the blade pitch seems identical between the two but maybe one is a half turn from the other or somthing ?
other than that I am at a loss for what might be wrong , any ideas ? as always thanks in advance .


note to self , maybe scale would be more rewarding than 3d , I think I would break fewer parts lol
