Perhaps one of you who have completed your installation can answer a
question.

What is the maximum throw of the pilot/copilot crossovertube at full
aileron deflection? Unless I've overlooked it, this dimension is not to
be found in the construction manuals.

With the roll servo pushrod connected to the capstan at one end and the
crossover tube saddle at the other end, how many degrees left or right
of top dead center does the roll servo capstan rotate with full aileron
deflection? It looks as though rotation beyond the 10 oclock - 2 oclock
position (approx), could result in control linkage lockup. There is a
limit stop attached to the roll servo brackets but it is at the 9 oclock
- 3 oclock position and at these extreme deflections, the control
linkage does lock up.

BTW, I have not yet connected the linkage between the aileron bellcranks
and the ailerons themselves so have not yet set aileron travel. If full
aileron deflection results in control stick crossover tube travel of
about an inch or so max in either direction, then all will be ok.

Thanks for your help.
