Dan,
I had never done an all out speed test with the SportHawk, until this morning.
At 3500? MSL, 25?C for a DA of 5150? she indicated 140 MPH and trued 151 MPH. The prop was turning 2950 RPM and the fuel flow was 13.2 GPH at 100? ROP.
(I couldn?t fly at 2500? MSL because of all the dust and dirt, my field elevation is 2803? MSL
Looks like our planes will do about the same on the big end b my cruise at 75% power (8.4 GPH) is 130 to 135 MPH. It sounds like that your plane may be a little faster than mine. My prop is a good bit flatter than yours but I need the power to fly out of mountain strips.
I am on the trail of the 150/150 manual that Carl Chitwood mentioned. As you stated there are so many variables that it will most likely not mean a lot for my plane but it still would make interesting reading. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" /> <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
