Sanstroem Friendship 3
The Friendship 3 is a French ultralight aircraft with tandem seats, engineered in France and Switzerland, and assembled in Czech Republic by Ivanov Aircraft for the manufacturer, R,S & Associes SAS Erik Sanstroem of Versailles, Yvelines. Inspired by 1950s and 1960s light aircraft and motorgliders, the Friendship 3 is a two-place tandem-seat ultralight aircraft with dual controls, so that the rear seated passenger can also fly. The company seems to have been founded 2012 and gone out of business in 2014. Design and development The Friendship 3 was designed for both Gliding, soaring and cross-country powered flying, with a glide ratio of 24:1. The Friendship F3A has a composite fuselage; and wood and fabric for the wings with the main spars in carbon fiber. The aircraft was Aircraft registration, registered in France in late 2012.

Ultralight Aircraft
Ultralight aviation (called microlight aviation in some countries) is the flying of lightweight, 1- or 2-seat fixed-wing aircraft. Some countries differentiate between weight-shift control and conventional three-axis control aircraft with ailerons, elevator and rudder, calling the former "microlight" and the latter "ultralight". During the late 1970s and early 1980s, mostly stimulated by the hang gliding movement, many people sought affordable powered flight. As a result, many aviation authorities set up definitions of lightweight, slow-flying aeroplanes that could be subject to minimum regulations. The resulting aeroplanes are commonly called "ultralight aircraft" or "microlights", although the weight and speed limits differ from country to country. In Europe, the sporting (FAI) definition limits the maximum stalling speed to and the maximum take-off weight to , or if a ballistic parachute is installed. The definition means that the aircraft has a slow landing speed and short ...
