Hi guys,
My V977 emits this squeaking noise as it spins down after I shut the throttle off. It didn't do this when it was new. I crashed it indoor last week and have since replaced 1 ball link, both main rotor blades and the main gear. The other parts are in immaculate condition. The rotor gear had been installed too far out, i.e. the top of it flush with the metal shaft's tip. I have since pushed it back in. The main rotor shaft now sticks out 1mm from the bottom of the heli.
Apart from what I've mentioned above, everything is like now.
What / where should I start looking to diagnose this squeaking noise?
Thank you in advance.
