I'd love to build an electrically powered RCR GT40, for all sorts of reasons, and believe I could live with the obvious compromises. I suspect though that it in order to achieve a good weight distribution it would be necessary to fit some of the batteries in the fuel pontoons (if that's the correct term). I haven't investigated the dimensions of different battery types, but I guess it might be necessary to modify the pontoons. Are these as I suspect essential for the strength of the car?
Have you looked into the possibility of offering the GT40 as an electrically powered vehicle, Fran? If not, are there any obvious reasons that it might not be suitable?
