If you look at the pitch speed and amprage of a 9X9 and 10X10 props, they closely mirror each other at lower power levels.

I "calculated" 75mph pitch speed with one, and 76 mph with the other. The amprage was very close between the two, being slightly higher for the 10X10 obviously. Theoredically, a 5X5 and a 10x10 should have the same pitch speed at the same rpm"s, but obviously, the 5X5 would have much less thrust. This is an over exageration obviously...

The 11X10 might produce more thrust, while not moving the air as fast, as a 10X10, giving you close to the same numbers.

Also remember, this is just a calculated guess, not a garentee. Still use your watt meter.
