I uploaded an attachment; we shall see what happens.

Picked one item 10X10 prop to see if it comes close to what I actually read on the test which was 30.46Amps/310 watts. Curiously, an 11X10 got 30.53Amps/300watts.

Cells = 2
Gear Ratio = 1.00
Diam (in) = 10.0
Pitch (in) = 10.0
Weight (oz) = 52.0
Batt Amps = 6.5
Motor Amps = 6.5
Motor Volts = 3.4
Input (W) = 22.4
InPLd (W/lb) = 6.9
Loss (W) = 7.8
MGbOut (W) = 14.6
OutPLd (W/lb) = 4.5
MotGb Ef(%) = 65.3
Shaft Ef(%) = 30.3
Prop RPM = 3071
Thrust (oz) = 5.3
PSpd (mph) = 29.1
RofC (fpm) = -159
Time (m:s) = 24:49

Does not make sense to me; maybe having a gear ratio of one is wrong. I don't know.

My brain is starting to hurt!!
