The Blue Yonder Twin Engine EZ Flyer is a Canadian designed and built, pusher configuration twin-engined, tandem two-seat, open cockpit aircraft provided as a completed aircraft or in kit form by Blue Yonder Aviation.

Taking inspiration from the twin-engined Ultraflight Lazair and the Leza-Lockwood Air Cam the aircraft was especially designed for the air-to-ground photography role and also for use over hostile terrain where twin engine safety was desirable.

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.

Like the original EZ Flyer, the twin engine version has an open lattice, "N" girder fuselage constructed from 4130 steel tube along with an enlarged vertical tail to improve handling in engine-out situations.

[1] The Twin Engine EZ Flyer can be equipped with a variety of powerplants, all mounted side-by-side in pusher configuration:[4] Despite being widely demonstrated and reviewed, the prototype remains the sole registered example.
