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.
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.
In the basic ultralight version gross weight is limited to the category maximum of 1,200 lb (544 kg).
[1] The EZ King Cobra can accommodate a variety of powerplants:[5] Despite being widely demonstrated no further orders have been received for the type and the prototype remains the sole flying example.
