Ultralight gliders, powered or unpowered
Gliders have been around since before powered flight. The very early gliders were weight-shift devices. Back in the 20's the "Primary Glider" became popular. It could be launched with a tow from an automobile and had effective control devices. Now we have a new wave of light weight aircraft, including Goat, Bug, Enduro, Flybike, all single seat aircraft. The package includes both classic drawn plans and CAD. These gliders are of simple construction and can be launched by winch, tow, or down hill launch. Or what if you add a small engine?
