With his present modified Great American = two-blade=20 prop he gets about 219 mph TAS at 8500' dalt at 2660 rpm.

The ELIPPSE two blade = prop just=20 designed for a 235/320 is predicted to give 216 mph TAS at 2700 rpm at = 14,500'=20 dalt, 224 mph TAS at 8800' dalt at 2760 rpm, and 230 mph TAS at 2300' = dalt, 2850=20 rpm.

Paul,

What is the typical static or take-off RPM with = Oscar's=20 modified Great American prop, and your "just designed" 235/320=20 prop?
