I used a 28 series outrunner to power my 2.2 crawler. Used a pede metal gear trans. 32p spur and pinion. 833kv motor on 3s lipo and a sidewinder esc. It ran great, way more power than 2 brushed 540 motors. I had to run 32p gearing as the motor has a 5mm shaft. I used a lower kv motor cause I could not get as much reduction with the 32 p gearing. Think I ran a 14t pinion and a 54t spur. So only around 4:1 ratio. Pyhsical motor size was only about the same as a 540. Pretty sure it was a 2826 size motor.

I have run 22 series axi motors with a 1.9 rig and a sidewinder. Had plenty of power, but startup took a bit of tweaking with the esc to get just right. Those motors are a bit small.

I agree that sensored setup would be good, I ran a noval 13.5 in a basher/crawler that I made. Did 20mph and crawled very well.

Sensored outrunner would be the best. Some have made them, but I would like to see a factory example. Castle mmpro would be a great sec to do this with.
