IPE KW 1 / KW 1 Quero Quero
This Brazilian single-seater training glider, known in full as the IPE KW 1 b 2 Quero Quero II, is a development of the original KW 1 designed by Ing Kuno Wiedmaier and made its first flight on 1 October 1972.
The Quero Quero is a cantilever high wing monoplane with the same Wortmann wing section as the Scheibe SF-30 Club-Spatz, which it somewhat resembles, and is of wood and Brazilian pine plywood construction. There are spoilers in the wing upper and lower surfaces, and the wing tips are turned down to provide an endplate effect. Landing gear consists of a non-retractable monowheel and a tailwheel, and the pilot sits under a one-piece detachable cockpit canopy.
Certification from the Brazilian CTA in the semi-aerobatic category, with an extension for cloud flying, was awarded in December 1976 and the Quero Quero II was put into production by IPE – Industria Paranaense de Estruturas at Curitiba in the state of Parana. By 31 March 1979 IPE had completed 28 Quero Queros, consisting of one static test and three flying prototypes, a pre-series of four production aircraft, one of which was lost in a nonfatal accident, and all of a second-series batch of 20 Mk IIs, which were in service with various Brazilian clubs.

IPE 02 Nhapecam
The 02 tandem two-seater, known as the Nhapecam, is the second training sailplane from the Brazilian firm of IPE – Industrie Paranaense de Estruturas at Curitiba, and has been under development for some months; it made its first flight on 24 May 1979.
The 02 is a cantilever shoulder wing monoplane with a modified Scheibe SF-30 Club-Spatz wing section; it is rather larger than the Quero Quero II, with a span of 16.60m (54ft 5Vain), a longer, more pointed nose and a lengthened one-piece cockpit canopy under which the two pilots sit. There are spoilers in the wing upper and lower surfaces, and the landing gear consists of a non-retractable monowheel and a tailwheel. A powered version of the 02, the IPE 03, was under development; this has a repositioned low wing and a retractable landing gear, and probably a 60hp Limbach powerplant.
An order for at least 30 IPE 02s for the Brazilian Clubs was confirmed in 1980.

I.O.W. Gliding Club

Ion Aircraft Ion 100 / 105 / 110 / 120
Ion Aircraft is developing a line of light, two-seat (tandem) airplanes suitable for training, sightseeing, cross-country cruising, and generally having fun. All of Ion Aircraft’s engineering is being done by AirBoss Aerospace of Reno, Nevada.
The Ion 100 is a kit aircraft being designed from the ground up to be Light Sport Aircraft (LSA) compliant.
The Ion 105 is a non-LSA variant of the 100, with better cruise performance. The 105 version is meant for the US Experimental category.
The Ion 110 is the export version, intended to comply with upcoming European rules.
All three versions feature easily removable wings for trailer storage and two sets of interchangeable wings to meet differing performance requirements.
The majority of the plane is carbon fiber/epoxy composite material. Specifically;
The cowl is fiberglass. Although it is very slightly heavier than carbon fiber would have been, the cowl is not structural and the fiberglass is much less expensive.
The wings are bonded aluminum as the bonded aluminum process is actually calculated to be a little lighter than composite would have been.
Tthe Ion 120 has a 10 inch (25 cm) removable nose cone to allow access to the nose gear and the batteries. It will also allow it to fit in a 24 foot trailer.

Invincible Aircraft Corp
USA
In the late 1920s the Invincible Metal Furniture Company of Manitowoc, Wisconsin, formed an aircraft division to build a four-seat cabin monoplane. The fuselage and tail unit were welded steel-tube structures, the wing of wooden construction. Access to the cabin was by a completely circular door on the starboard side of the fuselage.
