1981
Various gliders at our neighborhood field. Flying thermals
1985: New glider design: Opted for T-tail to avoid damage during landings.
Just released from bungee
2003: My experiment with tailless glider. Foam wing, with mylar covering.
Hard to see the orientation in the air.
Flying tailless airplanes is tricky: they tend to "overshoot" a turn.
Later-on I added some winglets for more stable flight.
