Algodoo

Fully mechanical wing that reacts to velocity and angle of attack.
UPDATE-new wing mechanism
-vastly increased glide ratio.
-plane now weights 550 kg
-separate speed sensitivity and angle of attack sensitivity via 2 springs
-added 2:1 gears to the mechanism. Now maximum lift is created at 45 degree angle of attack
-FLAPS - press f to activate
Glider is unpowered and uncontrolled, but turning flaps on/off provide some pitch control. That may be developed into control system for flying wing type craft.
