My RV-9A has a slightly heavy left wing. I applied full right trim and it had no effect. Since I did not build the airplane, I can't be sure the trim was
set up properly so, after verifying that the servo was indeed moving, I removed the springs. and replaced the seat pan. As soon as I get flyable weather,
I'll find out how much of a rigging problem I have, and deal with it. But clearly, there's something wrong with the trim system. Can anyone who has a
properly working version of this system give me an idea of how much force the springs should put on the stick. If anyone is really bored (or really helpful), a
fish scale pull at some measured distance above the seat pan, with the trim set at full right or full left, would be very helpful. Thanks.
