Gearing..ugh lol

Hears a tough one.. i have a HPI MT2-Sc conversion, roughtly 5.5-6 pounds with a 52 tooth spur, which I'm keeping because its titanium. Also, the motor is the castle 4 pole 3800kv motor, sc10 wheels, and thats about it.,,,now what pinion?

castle recomends from a 11t-15t for an sc10 4x4 with a 54t spur so.

If castle says 11-15t with the 54t spur,I'd stay around the 11-12t since your spur is 2 teeth less. That's my Opinion.

Free bump for some better qualified answers

Yea, the guy on ckrc.com says he has an 11t pinion, but he doesn't say what motor hes running so., but, thanks!, all just buy a couple and test them

Another gearing prob.- I need a 11t 3.17 size pinion gear, but i can't seem to find one, there just ones for helis.?-Do you guys know where i would get one?
