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!!

Why are you worried about finding a pusher prop. You can use a regular prop, just make sure the numbers on the prop are facing forward. There is no difference between a pusher prop and a regular prop. A 5x5 on a 2500kv motor with a 3s battery shouldn't be an issue so I'm not sure why your motor is getting hot unless there is something wrong with your motor. I use a 5x5 on a 3600kv motor without any issues, and it is a pusher using a regular prop facing forward.

Jim, there is a difference between a pusher and a normal prop. They are designed for opposite rotation directions. How ever with a brushless motor you can reverse direction so you can use a normal prop as a pusher as you say.
