After crashing and reparing, one of my rotor blades will not change pitch when I move the collective stick. The swash plates move in unison as they should. It is as though the pitch linkage were not there (it is). I can not see any other signs of damage or broken parts. Could it have something to do with the main shaft?

Thanks for the help

are one of your ball links broken off of the swash plate

No, all the links are good.

just thought of this is one blade grip stuck so only one moves

reiffron:

Thanks for the help and interest. I took the heli to the experts at one of the local hobby shops and they found nothing wrong with it. They said it is OK if one blade does not move with the swashplate as long as they both move when the blades are turning. (?!?! I'm new to this). So, I installed new rotor blades and recharged the battery and the thing is flying like new. This helo thing is going to be a big learning experience.

Again, thanks for the help.
