Rudder trim tab

[redacted]

My rudder trim tab is dead straight, never been touched since the plane was rebuilt. I need a heavy right foot to keep the ball centered and I've just put off making the adjustment. My question is - is it a servo tab or antiservo tab? Which way do I move it for more right rudder?

Just a thought on the rudder trim question. I have seen instances where the tailwheel itself was not rigged to be perfectly aligned with the rudder when in flight. The tailwheel then becomes in effect, a trim tab of sorts. Easily checked with the tailwheel off the ground and the rudder centered. Rudder pedal return springs have been known to break also resulting in assemetric rudder pressure. May be a few other things worth checking before bending the tab.

I agree, check all the rigging, but to answer your question, bend it left to force the rudder right.

Before bending the rudder tab be certain your airplane is rigged properly. The rigging instructions are in the MX Library.

Copy all, thanks. I’ll wait until we swap the flap brackets on the left wing before I mess with it.
