  For all you guys currently flying, particularly RV guys with 2.17:1 PSRU
ratios. I'm getting ready to order a prop and the manufacturers are asking
questions about desired prop RPMs at various performance points. Before
responding with uneducated guesses I thought I'd ask the group for their
numbers. Could you all please respond with the following:

1) Max RPM

2) Max Cruise RPM

3) Economy Cruise RPM

4) Static RPM

  Also specifically for the RV guys it would be helpful to know what TAS
(at what altitude?) you have at data points 1 - 3 above. And if there's
anything else you can think of that may be helpful please add that as well.

Thanks,

Mike Wills
