Re-posted since my previous post was pushed together.

I had a friend give me one of his larger motors and ESC so I did some experimenting. I did the test with a 2200 mahr 3 cell battery that was about 50% charged ( 11.6 volts). Prop 11x5.5E APC .

Full throttle test

Original Motor Propdrive V2 2836
1000 kv, 400 watt, max current 30 A

RPM 7,800
Amps 16.6
Watts 188
V full throttle 10.8

New larger Motor GForce 3536
1100 kv, 450 watt ??, max current 43 A

RPM 9,100
Amps 26.6
Watts 288
V full throttle 10.4

As you can see a LOT more power. This isn't an airplane that I would fly at full throttle all the time, so if I only fly it that way for a very short periods, my flight time might be somewhat similar? What do you think? Does my testing results look valid to you? I am somewhat new to electric motor power so any advice would be welcome. thanks
