after a few hard crashes my mcx2 now vibrates,,, if its in my hand it wont do it at all, but once its in the air it vibrates pretty bad, and at max throttle it stops i think. idk what to fix or look it or what?

please help, thanks

my MCX S300 slightly vibrates in the air. one of these days i'll finaly get to buying new shafts for it. may wanna try and replace the main shafts. try the outer one first... i don't think you need to replace both cuz the outer one have some separation from the inner so if the outer bends, the inside stays. i think. not certain. never taken it apart.

Check the main gears. Even the smallest amount of dirt or plastic in the teeth will cause a vibration. I sometimes clean up the gears carefully with a sharp hobby knife.

its not the shafts they are perfect, i sent it to the shop and they found out one of the motors was dead, so the top blades didnt really move, and ive only had this thing for a month, then on my 120sr the motor that moves the servo or w/e is messed up it makes a nasty sound and i only had it for 2 days when it did that...
