Tom,
You may find that not many are going to be able to give you anything but a guess. I can run some numbers for you on my prop software/servo torque software if you can tell me the engine size, expected prop brand, diameter and pitch and the engine rpm with said prop, expected weight, etc...
You know I didn't even think to put the numbers to it, but a 10" pitch prop at 6500RPM would give you 65,000 inches per minute, or just over 60MPH at 100% efficiency. I just thought with all the telemetry type stuff someone would have some real numbers. Tom
