To go way back to the original post on this thread, the issue is maintaining control of Scalextric cars with Carerra digital chips on a Carerra track without magnets. As many of us have indicated the options are - adding weight, aftermarket tires with more grip, and reducing the voltage. With the variable power supply on my road course Scalextric and Pioneer Trans Am cars are both fast and fun to drive.
In digital systems full voltage is sent through the power rails at all times, and control signals sent to each car's chip from the controllers tell them how much of the voltage to pass on to the motor. It basically moves the controller inside the car for speed control. Does changing the voltage effect digital chips and control systems? Seemingly not from some of the other comments here. If that is the case then from an overall perspective a variable power supply should be the best solution rather than changing the tires and/or motor for individual cars. A variable power supply may cost more than a person wants to invest, but all-in-all is likely to be a more economical solution than the combined cost of tuning individual cars.
The ultimate question might be, how do a few guys who are not interested in the tuning wars have some fun with digital racing without magnets most affordably? The variable power supply might be the best answer but who funds it and what rationale gets them out of the dog house with their wife or partner?
