[rhengst22]

Hey everyone I have a octura x440\3 on a impulse 31v2 with a leopard 4074 2200kv and a seaking 180 amp ESC. Is this a good choice for control and top speed?

If your running it on 4s you could easily prop up.

OK so if I'm running on 4s what would you reccomend? And what about if I'm running it on 6S?
