Bob,

Your HP-18 side-stick to center-stick is an example of good design.

Other designs that may be of interest to the group are Udo Rumpf's use of a
PIK-20 sailplane stick

Brian Case's HP-16 modification.

Brian need to lower the seatpan in his HP16 to allow more head/canopy
clearance. So he removed the old cable system which ran under the seat and
designed the following modification:

The second picture from the top tells the tale.

I'd assume (?) that there is something like a U joint behind the cockpit
to let the push rod line up with the elevator horn?

I'll have to think about this some more.
You guys just could be right!
