I am in planning stage of making a gravity racer, I see you have made a fantastic electric car, and no doubt have put a lot of effort into reducing the rolling resistance. Can you give any tips you have learned during the process? Also where did you purchase the wheels?
This week River Raiders we found out there was an error with the results at the EV Challenge and Team SKM beaten our time in the first race in the second race. Well done to Team SKM and unfortunate that you did not get the recognition on the day.
Not too much more to get a rolling chassis so we can test the layout, driving position and balance. The next challenge and probably the most time consuming is converting the sketches and models of the body into the real deal. We have talked about using fiberglass, blow molded polycarbonate, vacuum formed plastic and a couple of other ideas. Anyway the first step is a solid full size plug or body form. Needs to be something readily formable and fairly sturdy. I have my eye on an old log that should be big enough. Might have to take to it with a chainsaw.

While we are thinking about how we can get a new class for racing EV’s in Australia, we’ve started building a new EV for the Western Australian EV Challenge. Will we disclose some of our secrets? Maybe, it might just inspire and encourage more people to build an EV or compete in the EV challenge.
