Does the RV-10 need electric rudder trim?
This is another tough question. I recently added rudder trim using a Ray Allen servo and the other associated parts. I flew over 285 hours without rudder trim, and although it flew just fine with minimal foot pressure on the right rudder (I had a trim wedge taped onto the rudder that compensated for most of the trim in a 165kt cruise speed), a trim wedge is only good for one airspeed. Therefore, I spent a lot of time with very slight pressure on the rudder pedal, and my leg got tired sometimes as we often fly greater than 4 hour legs. My suggestion is to add it as a definite option, or if you’re unsure, at least run the wires to the rudder and through the tailcone for it so when you realize you want it, that it’s not as big of a job. In addition, save panel space for a switch. I would, however, suggest installing it because doing it after it’s painted will be ok, but not as perfect cosmetically unless you paint the rivet heads perfectly. My trim block was too much in a fast descent, so
