Not in your wildest dreams!

You guys are wildly overpropping these things & costing yourselves a bunch of performance.

At sea level the 40 LA has its power peak at 13,400 rpm & the torque peak at 12,700 rpm, developing 0.78 HP & 63 oz-in of torque, as measured by real-world dyno testing. At sea level it swings a 10-6 at 12,100 rpm --already 600 rpm short of its torque peak & 1300 rpm short of its power peak. It would swing a 10-9 at ~10,000 & a 10-10 at ~ 9800 rpm -- about a light year away from either its power or torque peaks.

The 40 LA also swings a 10-7 and an 11-5 at ~10,900 rpm -- a long way off its peak performance band. You may think that it is pulling well with the 10-7 or 11-5, but it isn't even close to its best performance.

Very much better choices would be 9-6, 9-7, 10-5, 10-6 & 11-4, depending upon the airframe specifics and density altitude.
