the flybar is trying to fight with the cyclic inputs....

if you spin up the heli and hold it in your hand and then try to move it around pitching/yawing etc
with your hand [not the TX controls]
you will feel at a certain point where the flybar trys to vibrate and the heli does as well...this is the point where you loose all lift from the upper and lower rotors[and fall from the sky]

i had so many crashes myself like as you describe as i mainly fly outdoors
and have learned how to fix bent shafts. the only thing i replace mainly are the blades as i still use stock ones and not the Xtremes.


the CX2 was not designed to do fast forward flights and banking turns it really wants to fly steady and slow
with your flying skills I think youre ready for the next
step!! the Single rotor helis!!

good luck

let us know how your doing with the new heli
