I think the problem is that with a 12t over 10t you may have not considered the extra leeway in the motor mount and might have to extend one of the mounting holes because your gear meshing was too tight and causing the binding issues.
The mounting holes might have addressed the issue as well, but I wanted the build to be as stock/seamless as possible. I took the route of hand filing between the gears. It worked mostly, but the faster that motor spins, the more those tiny filing flaws reveal themselves. All a learning process and a part of the fun!
A 12t will increase speed vs 10t, not the other way around. You want 0.6mod pinion, make sure it's metric and not a 48p for example, nice tails pipes haha
I was looking for better low speed control over the 10t (plus the extra torque from the motor upgrade stripped the stock pinion). 12t seemed like a good move, but boy was I wrong!
@@Th3_Genius maybe you can find a 9t or 8t to gear it down but it can become fragile that small, unless you go with the gear reducing gearbox with a higher ratio and a higher speed motor, stock it's roughly 1:18 reduction with a 18k rpm motor, if you go like 1:35 you can get a higher speed 52k rpm 370 motor for instance, I went brushless but it's not without its challenge and quirks
