my beetlewight robot

[Jackpietrzak1]

I've set to get my first beetleweight robot up & running which will be themed on a snooker player the great hurricane Alex Higgins, which is going to be a fast moving electric axe.

I'm currently adding gear boxes from 2x 3v dc como motors & 1x 24v dc como motor to 3x 15v como dc motors, but I want is to get brushed speed controllers to have same 15v's as the motors which I couldn't find. 2 of the motors will be at the back attached to the back wheels & will have a belt & pulley system attached to the front wheels & 3rd motor for the axe will be linked to cam's to move the axe.

As there's no 15v brushed speed controllers & instend I got is turnigy brushed 20amp speed controllers (8 of them so got spears) to turn 12v 1000rpm geared motors that everyone else uses, I just wanted to know if turnigy brushed 20amp speed controllers over heat or are the turnigy brushed 20amp speed controllers meant to be use for featherweight (somebody told me that I need 20amp speed controllers for my featherweight, which now I got them they are small to be use as featherweight speed controllers)

If turnigy brushed 20amp speed controllers no good for beetlewights robots, what could weight class robot could I use them in. I'm planning a robot in the future which the turnigy brushed 20amp speed controllers could be useful.

Here's the brushed speed controllers that I got.
