Put together my race car today. It was really low on weight and I was pumped.
-Too light or not enough downward force. Balloon flew off the ground when released.
-Added weight, went from 13.183g to 39.038g by adding a wing and quarters, stayed grounded and moved pretty fast.
Future design notes:
-Will be longer and wider. Thinking of a drag racer with a wider wheel base.
-Need to direct the way the balloon deflates, it redirects the car when it falls to the left or right.
