I have just finished putting together a World Models T-34 and I know these things are raced with 46FX's on the front.

What I want to know is what prop are these guys using on their 46FX to get the speed out of this plane?

What sort of speeds are they getting?

I won't be joining the racing anytime soon, but I do want to practice some speed flying with it.

Also I wasn't really sure where to post this question, so if there is a better forum please let me know.
