Who said you need a "pusher"?

Sorry Yetti but I forgot you are new to this...

One of the great things about brushless motors, is that if the motor is running in the wrong direction, reverse any TWO of the three motor wires and it will change the way the motor spins...

Well what does this have to do with Pushers?

You don't need them!

Mount a standard prop BACKWARDS then reverse the leads and you are done.
