This question was asked by a member in the last few weeks and I know I scribed an answer, but darned if I can find it now. Perhaps the 'post' push of the icon didn't take. Oh well. I'll try to explain it a different way, if I can.

There are free-play specs for trim tabs on the straight tail elevators as well as the cockpit adjustable aileron tab on the 36's so equipped. The trim tabs are basically a counter force to relieve the force the pilot needs to exert on the control, for straight & level flight. In that respect, think of the aileron as a trim tab for the wing, and use similar judgement for your V-tail.

Another way of looking at it is if you need to ask, it is time to repair.

Note the forward rod end on the aileron push-rod is a left-hand thread. The bolt that secures that rod end can develop shank wear, so I suggest if you are looking to replace that rod end, having a new bolt available is a good idea. Note it is not standard hardware, and is kind of a bugger to remove & reinstall.
