14. Performance Predictions
More contact area on drive wheel means better grip
Smaller drive wheel requires less torque
A rough estimate for the time it will take would be about 20 seconds

15. Reflections
We changed our design to have more rope to drive wheel contact
We used aluminum because it was light and strong
Hardest part for us was getting a drive wheel
Over all we spent about $35 on materials
In the future we would implement lighter building materials
