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!!![:@]
Your main shaft will not cause drag unless it is really badly bent. Not enough gear backlash will cause drag!
And all the links on these helicopters, once again, are one-way. They should be turned by full turns only, or they will bind (causing drag!) and eventually distort and get too loose.
Here, yet again, is the pic:
