Hi Chaps Thanks for the heads up and advice. Having continued to delve into this I am gradually finding that there are relatively inexpensive components to be had. So it looks more doable than I thought as regards motors/speed controllers is concerned.
Oddly enough I seem to have got a Challenger I in sketchup, DL'd from the warehouse that I can use to design the kit of parts from..... Oh dear.....
