hi f4udoa
i think the f4u-1d produced 2000 hp military, 2250 wep right (at sea level)
loaded weight(100% gas and ammo, no external stores) of 12,039 right?
my sheet predicts atht in these conditions, under military, at sea level f4u climbs at at 3200 fpm at 180 MPH at sea level under WEP, and under military power climb at 2800 FPM at a best climb speed of 180 mph.
the aces high table lists, at sea level climbs of 3050 and 2700 in this loaded condition, which is a discrepancy of 4.9% under WEP and 3.7% under military power, which is within the expected error band of my program, so it really cannot be used as evidence either way, other than stating that it most likely supports the aces high model since its within the error band.
trying out the 190 dora, it yields a best climb speed of 4300 FPM at 188 MPH, which is 3.6% greater than that achieved in aces high. In general, after some testing, the program seems to over-estimate climb performance between 3-5% so id say that aces high FMs are generally quite accurate...
now if someone would like to go through all FMs and find if any discrepancies are over 5% then there might be an issue...
