Hi,
My first one which was just a modified tamiya one with some thick wire soldered to the back to help carry the extra current, but it caught fire so I've now turned to plan B.
This a car electric window switch so only has single speed forward and reverse. (all 4 wheels spin on take off and leave tyre marks on the tarmac!) I've made a metal bracket to mount it to the servo. Its rated at 20 amps so should be ok for a while, I've had a couple of runs out of it so far
I've taken the advice of the other guy who replied to my question and gone back the a standard 540 motor, the car seems just as fast as before. I'll see how long the motor lasts!
I will post some pice of the car (That is if I can, do you have to be a full member to have a showroom?) as I've done quite a few other mods including an aluminium front bumper and 2nd battery holder and a steel chassis strenghtening plate. Now all I need is some tyres which done wear out so quickly!
