Hi Gene. No yet. We had a meeting late on Friday I think it was, and there is a problem with our timing. We are still working it out. There is an air-show scheeduled for SDF (Louisville) plus the Derby and it's their busy time. I should know more this week.

I took at the manual for the PT-40. It just says ball link. I would have to assume it's a 2-56 size, which would make sense for that size plane. It would not be smaller because it would become non-standard with the rest of the linkage and they just wouldn't do that. So, I would have to assume 2-56.
