Design Process
Decided to first build a prototype to test ideas onso that we dont have to worry about perfect
dimensions and appearance.
Final version is the one where we carefully
measured everything and used colorcoordinated materials.

Skirt Design
We considered an open, full, and tubulardesign.
The tubular design was too complicated.
The open design didnt hold enough air in.
We finally decided on a full skirt with holesto let some of the air out because it issimple and reliable.

Number of Fans
Originally, we considered having 2 fans.
1 down for lift and 1 backwards for thrust.
Then, we thought
about using each fan
for both thrust and lift
by dividing the air
stream.
We finally decided to
use a larger motor for
thrust and a fan for lift.
