Thanks for the many suggestions and sorry that i haven't been able to reply sooner. I am actually in 3 design classes this quarter
The restriction given is pretty strict and can't be changed nor bent. Everything used has to be well documented and bought new w/ receipt. Oh,we can only have 1 motor and a servo for steering.
The group has decided have a larger 1 rwd and 2 front for steering. The chassis is modeled around the battery and most of the component lies ontop of the battery so the vehicle is slim and compact. We are still unsure of whether to have a rear suspension but so far the CAD model has the shocks set 45 deg and between the rear wheel axel and a brace from the chasis. From the CAD drawing, the center of mass is also at equal distance between the tires and approx the height of the rear tire.
These are the rear tires we're currently considering:
We are still a little worried about traction since we will be driving on tiles. Then again, I read that our motor isn't very powerful. How does everything sound so far? We are also required to test in a wind tunnel.. Would it be ideal to mold to body over the entire front that are sticking out or just the main body?
