Chris,
Prop performance can depend on the elevation of your flying site.IE: Higher altitude= thinner air.

prop question

What kind of performance??
I have tried the 11x6, 12.25x3.75, 10x7 and the 10x6 on my us40/tt46. The 11x6 and 12.25x3.75 were similar in performance (vertical and speed) but it did seem to hover easier with the 12.25x3.75.

I wanted more all out speed so I prefer the 10x7 (vertical is a notch below the 12.25x3.75).
