A question about converting remote control cars
Im with the majority that entering an RC car into a featherweight competition would result in its destruction. But if your friend wants to get into the whole style of RW perhaps before building a featherweight from scratch, then using an RC car is great, maybe not for competitions, but for having a muck-about with your mates, chasing your pet (if you wish to) or practising your driving. I used to do it before I built a proper featherweight and it was great fun.
On the other hand, Demolisher (Robot Wars, Series 1) - wasnt that just an old RC car? It went up against robots as large as heavyweights and seemed to survive well.
So basically, RC cars, good for fun and driving, but not likely to last long in competitions. :)
