I know some would never use this, but I'm not uppity and more DIY with finding solutions for my SA. Put this on my steering wheel a couple years ago, very simple and works great! Also, people having issues, just don't go WOT on takeoff, ease into the throttle. That does 2 things, keeps the prop from slipping so it engages better and uses less gas and it gives the driver time to correct the rudder to straight while not being under load.
