We have started with the rudder now and I am trying to make up my mind on the rudder trim. I would love some input on this.
Is it really needed or just a luxury?
Jan, I have put adjustable rudder trim on my last 2 RV's, having had the fixed trim on the first 2. It depends on the type of flying you do. If it's primarily at one altitude/speed, then a fixed trim will work fine. If do a lot of cross-country, and you fly high and on autopilot, it is really nice to be able to completely trim the airplane for climb, cruise, and descent. I really like seeing the airplane completely trimmed in all 3 axis while in cruise, especially when IMC.
Better to have it and not need it then to not have it and want it.
I have just returned from a 32.5 hour x-country trip and as soon as I returned, I ordered the ML Skunkworks rudder trim. I have a 16 month old 9A with 230 TT. The system works on the same principle as the aileron trim, biased springs. The good part is that it is installed under the instrument panel with the two arms clamped to the rudder bars. A very clean install. I would encourage you to check it out before cutting the rudder and engineering then installing the associated monkey motion. Dan.
Seems like there were threads about springs on the peddles to keep the rudder from flapping in the breeze when parked. If I recall, some put 2 springs on right side so it acted like a trim tab.
Wouldn't this work?
I'm asking because I am thinking about the springs instead of a tab install since paint time is coming up.
