Default Small Pusher Props??

Hi Guys,
I have built an F22 Foamie designed for twin pushers and bought two small Brushless 2500Kv outrunners from Unitedhobbies for it. The smallest pushers I have seen are APC 5.5X4. I bought two of those and cut them down to 4.25" but they overheat the motors very quickly. Seems most guys are running 4X4 or even 4X2.5 on them from the reviews on the website. Does anybody know where I can fins smaller pusher props or have any other suggestions? Am I correct in assuming that they are overheating because the props are to big? I am running on 3 cell Lipo by the way. Thanks for any input you may have!!

With an electric they dont need to be "pusher" props. Buy a regular prop in the size you need, and put it on the motor "backwards", reverse the rotation of the motor, and youre in business.

Just swap any two motor wires from the motor to the speed control and the motor direction will be reversed.

Or if the ESC can be programmed. Reverse the motor by reprogramming the ESC.
