I'm not sure either :}

Are you looking to reverse the motor?  Do you need electronic reverse?
In not then you are looking at an aero BL ESC of just enough amps rating to survive in a nice cooling airstream
What motor are you using, what will its current draw be on the prop you mention at your voltage?

Fortunately all this data exists (cos the areo freaks enthusiasts need to know in order to be able to achieve aviation)
Many manufacturers list and tabulate this - let us know what and which, and which prop and someone will be able to give you the amps and them you need the next larger convenient ESC :}
