    Gearing help for CC 2650KV (1512)

    Greetings,

    This is my fist post on this forum, but I have a Stampede 4x4 VXL that I've upgraded pretty heavily (MIP heavy duty CVD, 17mm hex wheel conversion, aluminum suspension arms, casters etc...).

    I upgraded the motor and ESC to the Castle Creations 1512-2650kv motor and Momba Monster 2 ESC, and bought a few 5mm pinion gears but they were all 1.0 metric pitch, not the 0.8 (32P) that comes on the stampede by default. So I got a mod1 1.0 metric pitch spur gear, but it was only 40T, not the 54 that's standard.

    So it seems like I either need to a get 5mm shaft/bore 32P (0.8 metric pitch) pinion gear to match the 54T spur gear, or use the 40T 1.0 pitch spur gear with the 5mm 1.0 pinion gears my hobby shop has. I'm running 3S now, but will be upgrading to 4S soon. I mainly bash off road, but also on road and was happy with the original 11/54 that it came with, so curious what I should run now and if there's a benifit/trade off regarding the 32P/0.8 vs 1.0 metric pitch gears

    You should not need to go mod 1. Gearing depends on your goals and your environment. That said, I have that motor in one of my pedes and I use 18/54 (32p). I mostly bash it and with that gearing it's crazy fun and never overheats.

    Yea, I have a pretty decent sized property that's pretty wooded, so it's more bashing and off road than on the pavement, so I had a feeling something in the 10-20T pinion/54T spur gear range. I bought a set of pinion gears in the 13T-18T range, so I'll be able to try it out tomorrow and I'll see how 18/54 feels and go from there. I don't think I'm going to mess with the mod 1 gearing stuff until I find a reason to do so.

    Thanks for the advice!
