Thanks. There seem to be pro and cons to all methods of programming. That method is nice because it doesnt require dip switches on the car, making the package smaller. However, everyone needs to stop racing to code a car.
The carrera method is nice because you can code cars while others are racing. Its easy to take off one of the ghost cars, code it to a differnt channel without disrupting the other cars. On the down side, you need access to the dip switches.
I wonder how SCX does it.
