Just for the avoidance of doubt about driven wheels...
In F1 the car is only allowed four wheels, the front two of which may steer and the rear two of which may be driven. Since the front wheels have brakes they are clearly not driven otherwise they would not be allowed.
You can only drive things by giving an energy input from an 'engine' - simple physics and mechanical engineering definitions. There is nothing in the BRCA Rules to prevent front wheel brakes being fitted and used providing a Y lead is used for the brake servo off the throttle connection. There is, however, Rules around the number of servos you can fit to to a receiver and that you cannot provide any feedback from the suspension to the servos you might want to actuate the those servos to stiffen springs, etc. Sleep easy in your bed, Jimmy!
As Terry says above, the potential performance advantage would likely be lost in all that weight and technical complexity. If it was that good, we'd all be doing it by now, or the Rules would have been amended to stop it! Love this debate...
