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.
