I've trimmed my slight cruise yaw by reducing the spring tension on one of the four springs that keep the rudders leaning towards the firewall. It's centered ball cruise from 160 to 220 kts no problem. For other combinations of power and speed I use those units attached below my knees applying slight pressure on the pedals. By contrast I do however very much enjoy my MAC servos on both roll and pitch (and my cool koolie hat on the stick). Peaning to my Dad (of ancients) meant tap tap tap with a ball pean hammer. This according to my Navy trailed super smart airframes guy is exactly opposite from what you want (in fact causing work hardening of the rivets). We drilled those out. Therefore, a single heavy hammer whack is the preferred technique. It took alot of practice before achieving a rivet that looked (and spec.ed) to those of squeeze perfection. Also, we filled the hollowed out rod end cups (I forget the name) with a hysol flox mixture to help gaurantee no internal buckling of the rivet. Ok maybe two or three whacks on a couple. I made a few pushrods more than once as you might imagine.
