I designed a helicopter that my SO kid wound up not using. Originally I had bearings on both ends. It was a nightmare to get a wound motor on. If you were winding the motor on the helicopter and had 2 team members then it wouldn't be as difficult but that would mean you'd give up using a torque meter to wind.
Eventually I built a new motor stick with the lower rotor fixed. This cured the difficulty of loading the motor and didn't seem to make the copter fly any worse. If you have one person doing the winding and flying then I wouldn't even consider using 2 bearings.

Was watching some of the helicopter event at our SO regional on Saturday. Can someone explain if there is a reason to let both rotors turn relative to the motor stick versus keeping one rotor fixed to the stick? Seems like I've seen successful designs both ways.
Thanks,
