Think Pennyplane when fitting out a no-cal. Use teflon washers on
the propshaft.
A light but stiff motorstick is paramount. Walt Eggert in Phila
built a no-cal P-38 detailed exactly like the one that he was the
mechanic for in WWII. One of the famous features was the use of
rolled tube motorsticks,split down the center line to save weight,
with zero torsional problems.
A real gem to see fly with counter-rotating, 3 blade props. He
always made winning flight times and used to kid how it was set-up
to mimic his full sized charge right down to the leaned-out engines
for long overwater flights.
