Standard RC car speed controllers are made to take from just a few amps to some
as high as 500+
voltage wise they go from 6v to 24v
I'm sure there is allot more but thats what I've seen. The speed controller in
my Traxxas Emaxx for example is made to handle 14.4volts and 160amps of constent
current.

| (...) Talking of overdriving Lego electrical components, I once used a 9V pole reverser switch to connect 4 12V train motors on a robot to a 12V 6A power supply. The robot used the wheels from the Big Cat Truck and was so powerful that it would run (...) (20 years ago, 14-Jun-04, to lugnet.technic)
