Hello again
I used the solar cars as a template and made a few little modifications so that the car still follows the rules and managed to get a drag coefficient of 0.38 which is a lot better than the 0.6 what I was getting from my previous designs but the only thing I am not sure about is that to get this drag coefficient I had to use more material for the car, I am not sure how much more weight is added yet because I have not yet finished the frame for the car but it is an estimated 1m x 1m sheet metal and about 2m of 30x30 box section, do you guys think its worth adding this material for a decrease of about 0.2 drag coefficient, I know I have not given you much to go off of as I yet do not have the weight values but could you please try estimate.
Thanks.
