Harry, I had quite a few SCX cars that ran satisfactorily for quite a while on the 16v Scaley track powered by twin wall warts, and I had others that blew within the first couple of laps. But once they're blown they are blown. I think I recall someone working out that the failure wasn't in the LEDs but in a transistor on the circuit. Just plain easier to chop and drop in a 100 ohm resister and protect them from the Russian roulette of running on 16v.

I don't bother protecting mine anymore as I'm now running on a variable power supply and never need to run over 12v.
