My son Derek scratch-built a 1.5 meter discus launch glider recently, and we went flying at the local farm grassland with it. He calls it the Pheonix. The foils are Drela AG series,the wing is a sanded solid balsa construction, tail boom tapered carbon, stab balsa, and rudder fiberglass faced foam. The plane relies on a polyhedral configuration for stability and is controlled with two channels, rudder and elevator.
This video was started well after the handlaunch, Derek having caught a good thermal and gotten the plane several hundred feet up, as well as a quarter mile or so downwind.
We follow the plane as Derek brings it back upwind at a pretty good elevation, turns it left across the sun, and finally brings it home to nearly my feet as I film. Three minutes on camera, close to five all up.
No motor, no engine, just some flying skill and rising air. Great fun! Good flying, D!
