outrunner 4060

[BrianG]

Just curious, but aren't outrunners generally supposed to spin rather slow? 1600kv @ 28.5v is almost 30k rpm; fine for an inrunner, but not sure about an outrunner unless it is specifically designed for those high rpms.

From what I've seen, most people who run outrunners replace the transmission and/or spur&pinion altogether. So, slower rpms work in that case...

i have been looking around some sites and threads i havent come across anything about to high an rpm not to say there isnt any and i know there have been a few boats around using in the 30k range with outrunners- well the goal here is a trying to keep the amps down and maintain a good bit of wheel speed turning 7" tires in some very deep mud. its geared low 3906 2 speed tranny 76 spur and 14/13/12 pinion, up to 30 sec wot with out burning anything up
