I agree that winding a two free rotor design is a two person operation. We wind
ours on the chopper as we're not flying by torque but winding to max turns all
the time. It takes a bit of practice but so far hasn't been any real concern.
Eric,
Which regional did you attend Saturday? One of my helicopters won a regional
in IL Saturday but I'm not sure which region. The report I got was that almost
all the Helicopters got caught in the rafters including the winner.

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.
