Thanks for replying, Hooligan. This is what it came with: https://www.spektrumrc.com/Products/...rodId=LOSB9999

Brushed 14 turn motor.
Here's the brushed ESC: https://www.spektrumrc.com/Products/...rodID=LOSB9522

I measured my motor, seems to be the same outer diameter as the one you linked.
The shaft diameter seems is .125 same as yours.
My motor is about 1.9" long.
So physically it seems like it should fit.

I can't get the pinion gear off - the grub screw is rounded out inside.

The manual lists 48 pitch 14T and 18T pinion gears and the spur gear is 84T.

When converting to brushless do I stick with the same # of teeth on the pinion?

Any concerns with the transmission getting bashed by the more powerful motor?
