Esc & prop

[scotthend21]

I have a genesis cat that I am upgrading the motor to a Leopard 4082 1450kv. What size prop and ESC should I use? I have 3 ESC's Castle Hydro 120, ETTI 150, & TURNIGY 180. I plan on running on 6S 2P 5000 mah. I am looking for as much speed as I can get out of this setup.

I say use the 180 esc and start with an X445.I ran a similar set up in my 37"cat.My motor was a 4082 1500kv on 6s.Went 62mph with plenty of room to prop up.

Thanks Larry, I think I'll start with an x447 since I have it laying around.
