EZ Flyer


The two-place ultralight trainer EZ-Flyer was designed by Canadian Wayne Winters, using a lot of the Merlin's wing and tail structure.

The LSA EZ-Flyer II has a chromoly steel tube fuselage structure. It is a predominantly triangulated structure. The engine is pusher mounted behind the wing and on top of the steel fuselage cage. It can handle all the bigger Rotax engines and Merlin indicates that the 80-hp Rotax 912 four-stroke engine.

It is a 4130 chromoly steel construct that is painted at the factory prior to shipping. The wing has an aluminum "D" cell, is Ceconite covered and strut braced, but sports a large wingtip "fence" at the end that was removed from factory ships for testing. The ailerons are not quite full-span but are hinged in a frise-type setup with no differential. There are no flaps, and the wing is a constant chord assembly.

The rudder tri-gear has a set of very heavy spring steel gear legs and 18 inch tundra tires. The EZ-Flyer II is 21 feet long, 6 feet high, and has a span of 30 feet. The wing has 165 sq. ft. of wing area, a 10 US gal fuel capacity, and is stressed to +4 and -2 Gs. With the standard Rotax 503, the 465-lb EZ-Flyer II has a max gross weight of 1000 lbs, leaving more than a 500 lbs payload.

The empty EZ-Flyer has a tendency to sit on its tail with the nose sticking skyward.

Dual controls come in the form of a long J-neck control stick, rudder pedals, and a single-lever braking system to the left of the pilot seat. The throttle is also on the left and is made prominent on the prototype by a small golf-ball-shaped handle that sits atop the lever. The front seat offers minimal protection from the elements with a small windscreen that does keep the worst of the breeze out of your face.

There is some notable down thrust evident in full-power operations that will require initiating a positive rotation until you get to a much higher than normal light-off speeds. Lift-off at about 35 mph and 350 feet.
