A buddy of mine who used to winter at Curtis shop mentioned that Curtis had used a spring type system to trim the elevator at one time. The spring would attach to the torque tube to relieve pressure off your arm, and was adjustable n flight. The Sonex uses a similar system. I am considering using this type of trim on an Avid Flyer. Does anyone have knowledge of such a system used or tried on a Pitts?

Thanks,
larry
