After takeover by Keystone, Loening set up the Grover-Loening Aircraft Company at Garden City, New York, as consultant, and built small amphibian flying-boat XS2L for U.S. Navy in 1931. Delivered XSL-2 experimental submarine-borne version in 1933.
Aircraft
Group Genesis Genesis 2
The prototype Genesis 1 flew for the first time in 1993, and various improvements were applied, resulting in the production version, Genesis 2. The later has slightly modified wing geometry, fully retractable landing gear and a ballistic parachute (optional).
The design provides for automatic control hookups, and a ballistic recovery parachute is intended to be fitted as standard. Kits and complete airframes are to be produced by Sportina Aviacija in Lithuania, the builder of the LAK-12. The production version, Genesis 2, is expected to bring empty weight back to close to that predicted for the prototype. Other refinements incorporated as a result of prototype flight testing include a change to the aerodynamic twist to the wing, a modified tip airfoil section and a retractable nose wheel.
The kit price in 1997 was US$27,900.

Group Genesis Genesis 1
The Genesis I is a standard class glider from Marion, Ohio-based Group Genesis and intended for the homebuilt market.
Chief designer Jim Marske was given a clean sheet and chose a flying wing concept, but with conventional pilot pod and tall vertical stabiliser, topped by a small elevator, not tailplane. Aerodynamicist John Roncz, whose previous work has included the world-circling Voyager, did extensive work with computer modelling to come up with the final shape. The wing is a stable aerofoil with several changes in section and forward sweep across the span, and initial pilot reports (four different pilots flew the prototype within its first dozen flights) indicate high stability and control coordination.
The small horizontal surface found at the top of the Genesis’ fin is used only to control the glider’s angle of incidence. The wing has reverse sweep in order to put the variable masses close to the center of gravity, and incorporates water ballast tanks.
The prototype flew for the first time in 1993, and various improvements were applied, resulting in the production version, Genesis 2.
Specifications are for the prototype Genesis 1 as designed : on completion, empty weight was substantially greater.

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:

Gross JG-2
Designer and builder, John Gross, built the 3/4 scale replica Grumman F9F Panther at a Mt Cotton property a few miles south east of Archerfield (Australia).
After 8 years of work, the homebuilt JG-2 took-off for the first flight on April 1 2006 at Kingaroy airport.
Power is from a GE T58-8F turbojet.
Gross Sky Ghost
The third design of Akaflieg Darmstadt graduate Frank Gross, following the Akron Condor and the Baker McMillen Cadet, the Sky Ghost was relatively advanced for its time. A two-place dual control glider was a relative novelty when most training was accomplished by the solo method of ground slides graduating to low hops, high hops and patterns. It had a single fixed main wheel, with a two wheel gear as an option. Gross made the first multi-place flight in the U.S. of over two hours in the Sky Ghost. An example is in the National Soaring Museum.

Gros-Bredelet GB-01 Gerfaut
An original one-of-a-kind homebuilt aircraft, designed and built by James Bredelet and Louis Gros for two to four persons. The aircraft had a cantilever wing and was powered by one 130 hp Continental IO-240-A engine. It first flew on September 4, 1982.
Gruppo Costruzioni Aeronautiche GCA.3 Eta Beta
The Gruppo Costruzioni Aeronautiche GCA.3 Eta Beta is virtually a tandem two-seat scaled-up version of the earlier GCA.2 Dumbo, retaining the V-tail assembly. The Eta Beta appeared in 1952, and was designed for both training and touring roles.
The fuselage is an all-wood stressed-skin structure and the wing is an all-wood monospar structure with a stressed plywood skin. Cantilever spring steel main undercarriage legs are fitted, and the enclosed cabin is provided with dual controls and HF radio.
