Step 2Stripping down
1st job was to strip it apart and remove the old speed controller and replace it with a Sabertooth from Dimension Engineering. You need to cut off the Electrolytic filter capacitors from the motors as they will blow under PWM motor control. Leave the ceramic capacitors in place to filter out some noise.
The body shell comes off easily and the lights disconnect via a small connector. I cut out the rest of the controller and receiver circuitry.
I added the Sabertooth temporarily and set it up for RC mode and an old 27Mhz proportional set I had lying around to test with. All ok, had even more fun driving it around under proper proportional control :)
It can move very quickly

And with the new speed controller, very slowly too !!
