I'm going by the rotax chart that shows 75% power is 31" MP and 5000rpm and
if I'm not mistaken 65% is 30" mp. I don't have the book with me right now.
The 5000' is right off the altimeter set at the closest airport altimeter
setting. Yesyerday we were at 6500' showing around 135 knots, to fly with a
Piper Archer and the MP was back to approximately 28" at 5000rpm.

Hi Dean,
Can you tell me the MP @ RPM setting that you see that correlates to 65% ?
Is the 5000' value you have derived after compensating for barometric
pressure and temperature ?
How are you verifying your speed, 3 or 4 axis runs, or some other method.
Thanks, Paul
