So had an interesting situation today, on take off with full flaps and trim adjusted to take off position, when I rotated and started climbing out the trim suddenly and suprisingly jumped to full up. When I say suddenly I mean it felt like the trim actuator gears are worn to the point that would allow the jack screw to slip. I have under 400 hours on the airplane and I'm surprised that the trim actuator would be worn to the point of internal failure. I removed it and can't see any visible problems but I have confirmed the scenario three times in testing. Kitfox was unavailable today by phone. Does anyone have a source for the trim actuator assembly? I need to have it ready to go for HSF.
