Sorry for three posts in a row but I wanted to know that if my main shaft is just slightly bent (flys smooth but body of heli vibrates) could this be causing excess drag and slower head speeds? It is easy to turn by hand but you never know...

I just increased the pitch links by 1/2 a turn and tried flying again with the same battry and hardly out of ground effect when it came slowly back to the ground...
WHAT DID I DO TO THIS HELI TO SCREW IT UP!!![:@]
