RV-8/8A Elevator/Aileron Trim Kit

Add Electric Aileron Trim to Your RV

The RV-7/7A,8/8A,9/9A, use a spring bias style of electric aileron trim. The servo is mounted below the seating areas of the airframe. The system  applies trim forces directly to the control column and can be retrofit or installed during fuselage manufacture. No external tabs are required.

Current builder/pilots of the RV-4 and 6/6A can adapt these spring bias systems for the 8/8A and 7/9A respectively. We no longer have kits for the older trim kits which utilized a hinged tab on the aileron trailing edge.
