Design 1
Pros: Stable design
Cons: Bulky and requires a long set up
Design 2
Pros: Simple and aerodynamic
Cons: May have balance issues, large and may require set up
Design 3
Pros: Aerodynamic, light
Cons: Might be too light to carry all components.
Design 4
Pros: Symmetrical and thin for aerodynamics
Cons: Center of balance is no in center of wheels
Design 5 – This design will be further developed
Pros: Light, aerodynamic
Cons: May have balance issues
Design 6 – This design will be further developed
Pros: Design is simple and symmetrical. Aerodynamic.
Cons: Parts may be crowded on AEV. Would have to be taken apart often.

The following are the criteria on which the designs are based on equally.
Stability – AEV must have a decent center of gravity and cannot place too much weight on small parts
Blockage – AEV must not interfere with the track that is it on
Maintenance – AEV must be set up quickly when taken out of box
Durability – AEV must be structurally sound
Safety – AEV must not easily fall of the track or fall apart
The group’s has decided to minimize weight and drag by creating a vertical design. The weight of all necessary parts will be evenly distributed.
