Medusa Afterburner V2 BL motors

[jacko]

I'm running a e-revo using fan cooled MM w/ cc bec & two 2s2p 8k SPC Lipos & a single KD 700HO motor on Maximizer beadlocks and Badlands tires. I'm thinking of adding the Medusa 60mm 2000Kv motor and plan to achieve 40-45mph. Is this a good idea or should i use the lower 60mm 1600kv motor instead? Gearing recommendations are welcome if anyone has done this on their e-revo. MMM is not an option right now btw.
