I just had a PA-18 recovered plus a lot of minor repairs for wear etc. on the last 20 years. On the flight home I found that I was constantly adding foward trim. On inspecting farther, I find that after resetting trim, the handle creeps counter clock wise ( nose up trim) . The handle turns 1/2 to 3/4 a turn and stops. This takes about 60 seconds or so.
The party who did the recovering and replaced the trim indicator wire says he has never heard of this situation and has no idea . The crank handle does not appear to be either too tight or too loose. Is there a friction adjustment for this? He did not think so.
Just brought the plane home Thursday so have not had time to look or flight test any farther. Just hopeing someone has an easy out for me by having an answer.
The job came out beautifully and on schedule. I will be reporting in the next week or so.
