I have been thinking about the engine off set issue.   According to
Tony Bengelis the Falco engine is off set 3 degrees.  From the RV
study plans, I find that the RV is off set 1 1/4  degrees. The
Tailwind is not off set at all.   These airplanes have similar
performance and use the same hp range of engines.   The RVs use the
same engine mount off set regardless of whether the engine is 150 hp
or 200 hp and anything in between.  Further more, the same off set is
used regardless of which prop including Constant Speeds is being
used.    If the off set is to counter torque, then why does it not
increase with more powerful engines?   Since Steve Wittman who makes
Tailwind Builders jump through hoops with all types of refinements to
get the last drop of performance,  did not think it was worth
bothering with, I am not too worried about it myself.

However, it  is possible in my fixture to shim the Motor Mount Plate
to any angle, left, right, up, down.  I can't see a problem with
doing so if that is what somebody wants.    Jerry
