REFLECTOR: Roll trim?

[Rene Dugas]

Dave, sorry to hear it did not work for you.  I have the same and it works fine.  I don't use it much unless two people are on one side of the plane.
Best.

Sent from Rene's iPad. A pleasure.  Go Apple.

Back then, there was an electric motor mounted on the aluminum bracket which supported the aileron cable connection to the control stick torque tube.  The motor used a string (yes, just a string) which was to be wound around the motor shaft and whose ends were connected to springs, which in turn were connected to the control stick torque tube.  In theory, the motor put force on the string, which in turn pulled the springs, which in turn applied force to the torque tube.  Rube Goldberg, anyone?  In practice, the whole thing never worked worth a damn, so I got rid of it.  1100+ hours and counting...
