I've got one of the Associated RTR RC10T4 RS trucks and would like to change the motor out for one with more kick. Off hand I cant remember but I think it has a 20t in it now. My esc can handle 14t and above motors.

i'd get an orion SV2 15t, get the pro BB if you can afford it, very powerful and fast motor, i have one in my B4 and its pretty fast, i have no compliants

the lug

This motor really cooks..............torque and rpms.........no kidding. Anyone who reads this post that has one will agree 100%. The 27t moniker is deceiving, gear it how you like..............its a racehorse.

thanks for the replys guys, I'll check them out.

I used the Team Orion SV2 17t pro BB in my slash. It was a great improvement in top end and torque. It didn't last long...but I totally beat the snot out of it, so it does not surprise me. Here is a vid oh my slash running with this motor:
