Right looking at some info it would seem like you will need to be running a 55 amp esc and a min of 2200 mah 25c batteries,
Don't take my word for it though, there is alot more knowledgable people on here, but that's from what I have read,

Are you running helical cut gears? If so that motor should work. If not then you will need the 3950 kV scorpion motor. Typically a 3500kv motor is ran on this bird.
If you have the cash get a 30c or higher rating. As for the ESC rating you will need to figure out how many amps the motor will pull, then add 10 amps to that and call it good.
