I've had several people ask me to share my Electric Roll Trim system design. I installed this system when I originally built my EZ back in the late 1980's. SO, Its been a well proven system (2,600 hours) with no problems.
Basically, I used a MAC servo ( I think they are RAC now), made a spring loaded rod assembly, then attached this to the Aileron torque tube in the rear seat.
Check out all the photos and instructions at:

The only change I made was to rewire the MAC Servo so I can control it using the Infinity Stick Grip, rather than the original momentary contact switch that was recessed in the left armrest panel.
Good Luck
