Development
The EZ King Cobra was designed by Wayne Winters of Indus, Alberta and based on the earlier EZ Merlin. The project was started as a customer request for an ultralight category scale replica of a fighter and was later offered as a commercially available kit aircraft.
Winters created the EZ King Cobra by designing a new cantilever wing based on the Merlin wing, itself based on the Lazair wing design. The fuselage is constructed of welded 4130 steel tube and has a canopy and fin that resembles the original fighter design. The aircraft retained the Junker's ailerons of the original Merlin wing along with the Clark "Y" airfoil and construction featuring a leading edge "D" cell and foam ribs. The prototype is powered by a Rotax 582 two stroke engine of 64 hp (48 kW).
The prototype of the new design flew in 1998. In the basic ultralight version gross weight is limited to the category maximum of 1,200 lb (544 kg).
The EZ King Cobra can accommodate a variety of powerplants:
