Unless you have modded your Corsair to a pusher configuration, I wouldn't recommend using this pusher prop...

I use turnigy 9x7 3 blade on my airfield 800mm F6 Hellcat and P-47 they work great. Just don't fit in the stock spinner but great performance.

It's a pusher. Won't work on the front!

You can make them work in a "tractor" application - reverse the brushless motor by trading any 2 of the three leads - the motor will spin "backwards" (clockwise from the front) and the prop blade profile will be correct

This is a problem since most planes are designed with thrust angles built in for a standard rotation tractor prop. Spin the prop the opposite way and you are eliminating the purpose of thrust angle... Bad idea

Gregg, that's correct,changing rotation without changing thrust angles would create problems. This is sometimes beneficial in U/C, I've seen some electric stunt fliers do this. Little benefit for R/C.

You guys are also forgetting the most important point about this pusher prop. Reversing it to be a tractor prop would lower the thrust dramatically. Being thicker on the leading edge and thinner on the other. Plus the curve of the prop makes it useless as a tractor prop! If you Dyno this prop in clock-wise rotation, amp draw is 2/3 less and so is the thrust output!!!

Hey AutoRotation - we aren't suggesting simply spinning the prop the opposite direction, obviously that wouldn't work...you have to flip the prop over so the leading edge is still leading
