My Christen eagle and most aerobatic planes have a small

To stay in trim. Am I missing something in this setup?
Put the tab on whatever side of the rudder you want. For the RV-10 the ball was just touching the left side line in cruise (as in a little left rudder needed). Other planes will be different.
Note - do not add a rudder trim tab until after very carefully rigging the plane, including the wheel pants and gear leg faiinrg. If these are off just a little, you can get half a ball out on either side. Do not think “once and done” on rigging. This can be a multi-month process.
