I recently have been upgrading my electric converted Slayer I built about 3 years ago. I used the Techno kit with a Mamba Monster 2/2650 kv motor. I somehow reused the clutch bell but recently decided to get rid of it and moved the motor forward to line up a pinion with the spur gear. I have a 17t and 18t pinion but I was thinking of putting some 2.8" Badlands on it. Considering the larger diameter tires I was thinking of going with an 11t pinion. I mostly plan on running on an indoor track in the Rockford Il area so I'm not looking for speed. What would some of you recommend?
