Default Summit Tranny Spur and Pinion?

Hey guys I have a summit tranny with a Castle 4pole 5700kv motor and dont know what pitch or tooth to run; I dont want this to be a speed demon, just really confused on what gearing to run it at?

What veicle is this going in? Well with that motor its going to be a speed demon no mater what. that motor belongs in a slash 4x4 or a 4x4 buggy like a exo. That's way to much motor and it not even sensored. If I were you I would get a good sensored 13.5. If your going to try it anyway go with the smallest pinion and the largest spur that will fit and run 2s. 77 looks and not even one reply on this.????

Well its going in my hybrid buggy, its a slash front end with an ar60 in the rear. Im going to try and run a 68 tooth spur and a 9 tooth pinion and see what it does with the 2s.

yeah, I have a Pro4 4000 in mine and it does well on 3s. (11t I think)
Put the smallest pinion on you can find and the largest spur that will fit.
(I don't remember what I'm running... 68 or 86?)
32 pitch.
