Gearing Advice

Unless you couldn't hold your finger to the motor for more than a second, I would say it was probably just from running it in the grass and such.

Your currently geared for about 50mph seems about right. What are the ambient temps. Hot days suck, less room to work with if the motor starts at 90-100 from weather.

Gear it down a few teeth and see if that helps.

I was running 16/46 on a heavy basher e-raze in the grass yesterday and got the motor up to about 150 on a castle 2200 with a xerun 150amp. Grass got in the esc and stopped the fan, which runs all day everyday and still kept under 100. Took the lid off for a few full throttles and it got things running a bit cooler.

Get some air flow going and a tooth or two lower and you should be okay.
