I'm putting in the Leopard 4074 Motor Brushless Inrunner 2000Kv 4-Pole and the Hobbywing Seaking 180A V3 Brushless Esc , is this a good setup to run 5s and 6s and can anyone till me what size the Bullet Banana Plug are on the motor side of the esc , any hep well b appreciated .

Not sure why you would want to run 5 or 6s, 4s is plenty with that motor. 5s may be an ok setup with a smaller prop like an x440 but its really not necessary as you can prop up with 4s, x642 etc..........

Hi,

I've been running my Impulse 31v1 with a 4074 1800kv Leopard, 5S 40C batteries, Seaking 120A ESC, Octura x645 prop for several years. Get's up near 60mph. Very reliable, easy on the electronics.

So in your opinion if i run the Octura x642 i should have pretty much the same result's ?

The x642, 4S, 2000kv is perfect. The 5S is just outside the range, but still OK. 6S on a 2000kv is too much RPM and will draw too much current.
A lower kv motor will provide more torque for prop capacity (pitch, diameter) and can do so with higher voltage. Check out the OSE calculators to estimate speed an other metrics.
