Our car is called, “Chad Brad Bradley Mobile”, and our team name is “CHAD”, but you can call us by our car name. The car was designed by Nicolas J. in 7th grade, Jamie H. in 7th grade, and Marcos Z. in 8th grade, and was constructed in Cornerstone Learning Community. Our car is in a wedge shape to increase aerodynamics and speed. The main shaft of the car has lots of wood cut out of it to reduce weight and increase mobility.

Vehicle Performance Video
Tests
Test 1 (Battery): Sunny and clear clouds, 15ft, 6.98 seconds, speed was 2.1 feet per seconds. The rubber band came off so we had to attach more securely.
Test 2 (Sun): Sunny and clear clouds, 15ft, 7.5 seconds, speed was 2 feet per seconds. Removed some weight from excess pieces because it slowed down.
Test 3 (Sun): Sunny and clear clouds, 15ft, 6.2 seconds, speed was 2.4 feet per seconds. An amazing run.
Nice Performance!!

Great job, team! Good luck at Energy Whiz this weekend.
Clearly a lot of thought and effort went into the design and implementation. It actually runs better and faster than my own van! Good luck in Cocoa Beach.
