Today I tested my car using 2 wheel drive and no chasis and it was slower. Using 4 wheel drive gives the car more power and makes it go faster. The best set up is No chasis, 4 wheel drive, and Nickel Cadmium batteries.
Tested the Nickel Cadmium again with the chasis removed and it was faster. Although throughout the test the batteries were getting weak at its peak it was the fastest out of the rest. Next class I will test out rear wheel drive, switch the tires and use Nickel Cadmium batteries since they work the best.
