Designed by John Chotia and marketed in kit form by his company, Ultra Systems of PO Box 2253, Ogden, Utah, the Weedhopper is a powered hang glider envisaged as a low cost fun aeroplane that does away with the conventional hang glider's need for a hill and wind, and the bruises, hard landings and other exertions that usually accompany this form of flying. The Weedhopper is Chotia's 23^rd design, following 18 hang gliders of both rigid and flex-wing types, and five powered gliders of which several are foot-launched.

On 27 October 1981, John was killed in one of his own prototypes, the JC-35 Rocket, and on 30 December the following year the company filed bankruptcy papers. However, this does not necessarily signify the end of the company as John's widow, Susan Boman, continues as company president, following a reorganisation which has cut the range to just one model, the JC-24C.
