3. Fabrication Plan

4. Pre-Flight Testing Sandbag wing Cycle landing gear Drop test
Verify CG location
Check all surfaces for warps
Check all controls for range of motion / binding
Radio range check
Tests conducted as parts are completed and installed

5. Flight Test Plan Low/Hi-speed taxi tests
Familiarize pilot with ground handling characteristics; crew with aircraft operations
Flight 1A – 1x: Unpowered glide test series
Familiarize pilot with glide characteristics
Validate chosen CG location
Preliminary validation of control authority

6. Flight Test Plan Flight 2: 1st Powered Flight (outdoors)
Demonstrate sustained powered flight
Straight and turning flight
Gear will not be retracted; gyro will not be used
Flight 3: Envelope expansion (outdoors)
Evaluate corrections to Flight 2 deficiencies
Cycle landing gear
Power-off and power-on stalls
Flight with conservative feedback gain

7. Flight Test Plan Flight 4A – 4x: Final shakedown (indoors / outdoors)
Evaluate corrections to Flight 2 and 3 deficiencies
Tune gyro gain to desired value
Flight 5: Demonstrate design mission (indoors)
Fly mission as described in DR&O
