Thanks for the advice I have a Bec that should do the trick. the Sabertooth is going to be fitted to a 2 motor robot now. as the sidewinder takes no prisoners in the 4 motor pusher ram bot that is Tron.
Oh and for those that may be intrested I have put a steel spike on the front :shock: :shock: :shock: to sort out some of the little plastic robots that are arround.
