I want to run this by you guys - then I shall try the Super Cub folks.
We just had a Super Cub with very stiff trim. The fix was to adjust the stabilizers off by a degree and a half to compensate for what was undoubtedly a repair done without a jig. You can see it, although you cannot tell when flying. It is an appearance issue, and not much of one at that.
This is by all accounts not uncommon at all.
Len showed me a yoke that had a bronze insert in it - leading to a thought experiment: suppose we re- designed the yoke to allow the nut to shift - to align with the axis of the jackscrew? All it would take is Len's yoke with the bronze nut having a radius top and bottom - and not much of a radius at that.
Even on an almost perfect airplane this would reduce friction. Any thoughts?
