4. 5lb 10lb y x Balsa Material Properties Young’s modulus 1130 – 6000 Mpa Shear modulus 100 - 500 MPa Tensile strength 0 - 75 MPa Compressive strength 3.5 - 27 Mpa Material properties from Matbase.com. http://www.matbase.com/material/wood/ class4-5-10-years/balsa/properties

5. Flight ObservationProbable CauseActions Taken Wing sheared off during flight Purchased ply cut on RIT laser cutter is 3 layer, compared to 5 layer ply cut by Foxlite, Inc. Absorption and cure times increase for plywood applications Change ply adhesive to Gorilla Glue Redesign wing to accommodate double brace thickness and top sheeting Cyanoacrylate (CA) adhesive was more effective in balsa joints than ply joints Epoxy found to not completely cure

6. Enables onboard control switching between two pilots or a single pilot and an autonomous system Uses: - Autonomous system testing with pilot backup - Control ‘hand off’ between pilots a significant distance apart for extended range flights ~$50 total per system.
