Strong pitch trim jamming


Greg Norman
 

Last year my Strong pitch trim wouldn't move forward or reverse. Just shook in attempt. Thanks to the advise of this group and for sitting ten years in a build I removed it, cleaned the threaded rod and reset the motor for higher torque. All good until I had a friend run the trim to its limit. Now it's jammed again. As advised I have not oiled it and it's clean.
For pete's sake does this happen often with these? It's a pia to remove and would be real pissed if this happened in flight.
