Hi paul, or tracy

I have asked this question before, but no response.  It may seem off the

wall

however it is a consideration when making the marcotte/crooke decision

for

the PSRU.
I have been looking at the motor mount requirements for the RV8 and

noticed

that the thrust line is off-set approx 1" to the left of center.  If I

now

mount a reversed prop should I consider a similiar offset to the right

or

just go centerline?

Is that one inch or one degree. I think you might need to ask Van that

question.

There is an angular offset to the right in the stock mount but I did not put
any offset in my engine mount.  The offset is mainly to compensate for
P-factor during takeoff.   About the only real world effect is to the amount
of rudder needed to keep plane lined up during initial takeoff roll.
