32p spur gear for the EV?

My blizzard has an 'excess of power'... The motor mount bends and strips the spur gear...

Has anyone tried a 32p spur gear on the ev?


This one looks like a good candidate...

What kind of power are you putting though the drivetrain to bend the motormount?

40k is normal for fun toys...

I miss my emaxx with a pair of novak 4.5HVs on 4s. 5000kvx14.8v=75,000rpm. I had it geared for ~110mph, That was a fun truck, I should have never sold it. :/

I've had 1/10 motors over 100k before... The mamba 9000kv was a hoot on 3s in a jato, it was geared for 130mph and would melt the gears out of the transmission before I reached full throttle.

The rooster tails are fun... But it's funner to jump it up in the air(curb/etc), back spin the motor and do a front flip

is it possible the motor plate is already bent? I also have some 48p pinions where the teeth are very sharp, usually the fewer the teeth the sharper the teeth are is what I've noticed with the pinons I have. Maybe try a large pinion. Set your pinion/spur mesh with newspaper?

Belt drives have been done before... They aren't durable enough to withstand abuse, or dirt, or rocks, or...
