You need to get a way from those small motors and get a properly sized one or you will be fighting heat problems forever. Use the MM esc on 3s if you want, but run a 7XL and gear it up to get the speed you want.

I personlly would opt for 4s and an 8 or 9xl if it were me but 3s can work if the performance on 3s is enough for you.
