I bought a couple 'moteus' motor controllers from Josh Pieper at mjbots to build a small two axis gimbal to point an antenna. It was my first foray into any kind of hardware project of this nature and I honestly didn't fully respect the amount of force these small brushless motors can generate. My head is thinking 'these things run on batteries and meant to spin at 3000 rpm, how much torque can they have?'

A lot.

I've broken a half dozen mounts, ripped a circuit board in half and smoked a few passives in the process. My recommendation is to start with a small motor when you're tinkering with this stuff haha.

(I'm no expert but super happy customer of mjbots btw)
