I have my motor mount jigged up and am ready to start fitting the pieces
together.  My question is what dimension should I set between the forward
face of Tracy's RD1-C and the forward face of the cowl?  I am certain that
the PSRU is inboard of the cowl and it appears that this distance is about
2" on the several Lyco planes that I have looked at.  I assume that various
prop manufacturers would need different clearances and that there are
extensions available, but I think this distance should be somewhat standard
and I don't really have a clue as to what it is.
Thanks,
Bill Bradburry
