Accomplishments Designed, built, and tested a plane with the full intension of it crashing into the ground Manufacturing Aerodynamic Surfaces with Foam Cutter Integral 3d printed fuselage Implemented the novel plane wrap or “snuggie” idea Repair time was very low Repair costs were low Successful lift off Team and individual growth

Lessons Learned Designing a plane is easier said than done Durable materials are much more expensive than normal model aircraft material Hand launching the plane is not the best method Hollow carbon fiber tubes have low radial strength H-Tail is not a durable design

Moving Forward Purchase new speed controller and receiver 3D print control surfaces (lightweight/rigid) Remove material from motor mount plates to allow for more airflow Winch/launch system design 2 nd wheel for tail stability Snuggie design changes
