The Weedhopper ultralight is a single seat ultralight aircraft originally developed by John Chotia during the height of the 1970s ultralight boom. It came as a kit and, according to the manufacturer, could be easily assembled in less than a week. Many of the early ultralights used a “weight shift” method of control, requiring the pilot to push a control bar to shift the center of gravity of the aircraft. The Weedhopper differed from most other ultralights in that had a control stick which moved the rudder and elevator, giving it two axis control (pitch and yaw). The steep dihedral of the wings caused it to bank into the turn, and resulted in a very stable, easy-to-fly aircraft. The Weedhopper differed from many of the other early ultralights in that it had a strut-braced wing. Most ultralights have wire-braced wings.

Thousands of Weedhoppers were sold throughout the 1970s and 1980s. It was popular because it offered people an inexpensive way to fly for pleasure. The aircraft could be easily disassembled and put on a trailer for home storage.[1] It was not necessary to rent an expensive hangar. It could also be flown from just about any field because of its short takeoff and landing requirements (about 100 feet with no obstacles). The kits originally sold for roughly $2,000. Today kits are no longer available.
