Motor selection for Slayer

I'll be converting a Slayer myself when they come out and trying the Medusa 36-60 1600kv on 6s .

I have the 1600kv in my X2 truggy on 5s and a spare one for my buggy or Slayer , which ever i get going first.

If it's not up to the task i'll just get the 70 size when Medusa releases them , for the money they can't be beat .
