That would be excellent on 3S!

It would also be nice and mild on 2S too.

If you are going to be mainly running 3S, go with that.

If you're mainly going to be using 2S, then go with the 4200 (that way you can still do insane speed runs without things getting too hot)

Keep in mind that in the vid i was using six cheap, unmatched GP3300s.

On lipo you would have more current and more voltage - but if you are planning to run a mixture of 2S and 3S then the 4200 (or whatever it is) would be a good choice

There's always the Feigao option - the 6S is a very fast motor indeed - not as much low speed power as the 5300 but it really pulls at higher speeds. Just gear it quite low.

If you bought something like an 8 or 9S you could run both 2 and 3s lipo, save a bit of money and still have nitro-killing performance ;)
