If you have counter rotational props, which would be best, try out the Octura x442 L + R's.............but i would only run it on 3 cells each.......

4s may put you over the safe zone for the ESC's.............. If you have to go 4s then cut these down to around 38-39mm..............my opinion of course, lets see who else chimes in. 2700 kv is right in the 3s zone for a motor, what brand motor is it by the way..........and 2 pole or 4 pole?

PS, you running counter rotating?.............oh, and these are berylium

Forgot to tell you the make of motors.They are the FSD motors.Guess I will see how could they are.If they blow ,then I will get 2 leopard 4074.I will more than likely get the 3 cells start from there. Have a good one
