Mucho frustration.

I could not get my DPDT mini-relay switches to work. I unwittingly purchased the "latching" kind with two coils. Neither I nor wikipedia know how these work. Today I ordered the same kind that http://letsmakeroborts.com/node/928 used. 5 to 10 days delivery by land.

I have succeeded in separating the 6volt battery (powers the PICkit, the radio receiver, the steering servo and the proto board) and the 7.2 volt battery (powers the wheels and the electronic speed control). Under radio control the car still runs.

Next step CCP1 and CCP2 pin outputs to the speed control and the servo.
