OK.. I finished my landing gear modifications. With the mods, the 12" props have just under 3" of ground clearance.

Anyway, here's the info

Propsize Wp Wh Vm Ah V W A
11x6 832.5 8.0 17.45 0.871 20.03 715 40 (Master Airscrew prop)
12x6 815.9 2.3 17.25 0.313 17.3 714 41.0 (APC prop)
12x8 821.9 4.7 16.85 0.486 16.92 745 44.81 (APC prop)
12x10 1035.0 0.5 16.23 0.785 16.5 845 52.5 (APC prop)


I tested the props in the order listed. I would run the throttle up to full throttle to read a number, then idle it down for a few seconds, then repeat until I had all the numbers recorded.

Working with the 12x10, I noticed that after about 15 seconds of full throttle, the motor shutdown.

I did all the tests on one set of batteries. I can recharge the batts and try a specific prop again.


So... Having this information.. What prop? and Why?

TIA
