Pushing the limits of volting up and gearing down for a Crawler

Hey Guys,

Been lurking for a while and finally started jumping in and buying parts after doing a lot of studying.

I have an SCX10 II Kit version and a few weeks ago I bought a puller pro 3500kV and BLE PRo from Holmes.

I geared down to a 9T pinion and the performance is awesome and speed is just about where I want it to be on 4S LiFePo4 (13.2volts)

I was digging around on pinion sizes and see hot racing offers them all the way down to a 6T 32P size.

Soooo just for fun, I was thinking of going up to a 4500kV motor and down to a 7T pinion… to see what differences I feel. I am hoping for better low speed control and braking. Not that it isn’t great already, but can it be better?

Not that I need more torque, but it seems the faster the motor spins, the better it responds, brakes, etc…..

I am not worried about breaking parts, I just enjoy learning stuff and researching new parts to upgrade as a break stuff 😉

Will these small pinions hold up with a good metal spur gear in these situations?

I plugged the numbers into the calculator I made and the top speed is identical between 9T and 3500kV and 7T 4500kV….

So what do you say?

Attached are the results from the changes in my calulator.
