RV-7/7A/9/9A Manual Trim Kit

Manual Aileron Trim Kit

Trim Kits for Balancing Due to Fuel Burn and Loading

Kits are usually ordered with the fuselage kit, but are easily fitted to the finished aircraft. A real convenience for cross-country flying, trimming out uneven fuel burns, etc. Simple light springs connect to the aileron controls, unnoticeable through the stick. Installs entirely within the cabin. No need to remove wings or ailerons.  It is a spring bias system that manually applies trim forces directly to the control column. RV-7/7A,9/9A mounts between the pilot and passenger's seats.

This kit is NOT intended to compensate for aircraft with rigging problems.  See Chapter 15 of Construction Manual to balance aircraft prior to installing trim.
