I don't know. The one thing I did which improved mine no end on controlling
pitch was I lubricated the shaft with silicon grease. Before each session I run
it back and forth while turning it to its stops, which breaks up any friction
points. It operates MUCH more smoothly at that point.

I have that same yoke, which I hate. Your suggestion sounds like it's
got a lot of potential.

By silicone grease, do you mean the clear stuff, like "bulb grease?"

Thanks!
