In my case, I caught the problem on the ground. I have my trim dual wired--both grip and rocker switches on the panel. I had several instances of rudder trim running full stop from depressing the rocker switch during run up----the cause?----the Mac decal around the rocker was touching the rocker and not allowing it to reseat in the neutral position. After taking a razor blade and trimming the decal for more clearance, the problem disappeared. The Mac stick grips can be perfectly functional and still be a factor in run away trim as well---don't ever slip your palm over the top of the grip to get more leverage! I did this on my first departure in training with Mike DeHate, and ran the trim to full stop. Mike knocked my hand off the grip and retrimmed as we were approaching the end of the runway. He got us out of a very bad situation. (Another reason to have a factory pilot give you your first training in the plane) After that flight, I built an aluminum fitting that slides over the grip below the round top which contains the switches. This fitting keeps my hand below the top and on the shaft at all times. Thanks, Mike. I wonder how many other novice LIV pilots you have saved with your excellent training?
