well i think all you guys are right its the blades get off track with too much head speed. i have tried to give it pitch at a lower throttle and the wobble is gone, but am not getting the full potential of the motor.. its like the throttle is below normal operation of the heli but the wobble is not there.. it flies steady and can be easily moved around with good flight patterns but since the throttle is way below normal operations I am lacking the power to puch it when power is needed.. its like a FP heli that you power the motor with the amount of pitch.. switching to 3D will give the weird wobble and the heli is only good for FF an FFF.. I still have to look around for a small pinion. 2mm pinions are hard to find here...
