Grosso Aircraft Easy Eagle 1
The LSA Easy Eagle I Bi -Plane is an affordable, easy to build aircraft that combines standard aircraft construction methods, steel tubing, wood and fabric covering.
The 4130 steel tube fuselage is wide enough for 44 inch waist line and a 6 foot 3 inch pilot. The 300 pound useful load allows for a 228 pound pilot and 11 gallons of fuel. The low wing loading of 6.7 pounds. per square foot gives the Easy Eagle I Bi -Plane a low stall speed and great glide ratio.
The aluminum 5/8 inch landing gear and 5 inch wheels provide for easy handling either on paved runways or grass strips. With the optional hydraulic brake upgrade, ground handling is superior.
The Easy Eagle I Bi -Plane takes off in only 300 feet and lands in about the same, thanks to 105 square feet of wing area. Climb is 900 feet per minute at sea level.
With a stall at 45 mph or less, a cruise of 100 mph, low building time and simple straight forward construction, all combine to make the Easy Eagle Bi-Plane a single place, affordable bi-plane.
The airframe is rated at plus 4 and minus 3 g-s the Easy Eagle Bi-Plane is capable of doing many sportsman aerobatic maneuvers.
Featuring a fully welded steel frame combined with an all wood wing and a one piece aluminum landing gear, make it a airplane for today. Landing and taking off is made easy with a fully controllable tail wheel.
With a 64 hp VW engine the Easy Eagle cruises at 100mph and has a stall speed of 45mph. The Easy Eagle features a fabric covered fully welded steel frame combined with an all wood wing.
In 2008 the EASY EAGLE was available from:

Groos Quand même
The second design of French military officer Alfred Groos. Produced in 1909, a small monoplane which was named “Quand même” [“Nevertheless”].
It was tested on 30 July 1909 as it flew about 100 meter with a speed of 55 km/hr at a height of ca. 2 meter. When it came down one part of the wing was damaged and the propeller broken. The monoplane had a four-wheel undercarriage (2 bigger in front and 2 small ones behind) and a very simple “fuselage” – about one piece of wood – and was powered by a 25 hp Anzani.
Groombridge and South 1903 multiplane
Built in the UK, this 1903 machine, which was about 80 feet in length and 60 feet in width, was to be supported on superposed planes attached to the framework both at the front and rear of the machine. It had three propellers on each side of the framework, and an extra one surmounting the whole structure. The propellers were carried on arms extending from the central driving shaft which form an axis within a rectangle, the two vertical sides of which form axes carrying the vanes of the propellers. During the driving stroke the vanes extended outside beyond the rectangle, while they returned edgewise, in a feathering position, inside it.
