Working on a Starduster SA 100, that has a jackscrew controlling the leading edge of horizontal stabilizer for trim, there is about 1.5 inches of total travel on the forward end of the stabilizer using this trim system. I have not flown the A/C, but have been advised by a past pilot (very high time) that adjusting the trim on the ground was easy. But in the air it was nearly impossible (two hands required). The jackscrew is operated by a Cessna style trim wheel & drum with an endless cable to the jackscrew, the cable is not slipping on the drum or on the attach point on the jackscrew. I have cleaned and lubed the jackscrew and it operates from the cockpit with two fingers on the ground, again I have not flown the A/C, but it does have about 1,000 hr.'s on the clock. I have worked on a bunch of fabric Pipers with this same setup with no problems. Any ideas ? has anyone else run into this issue?
Thanks Phil
