The 3X55 Trener (Trainer) and 3X47 Ultra are a family of ultralight aircraft produced in Poland by the 3Xtrim Aircraft Factory. Both are two-seat, high-wing, strut-braced monoplanes with fixed tricycle undercarriage and available only as completed aircraft. There are also 450 Ultra and 495 Ultra Plus sub-variants of the 3X47 Ultra, with gross weights adjusted for national ultralight regulations.
The US light sport aircraft version of the 3X55 is known as the Navigator 600 and has a 1320-pound maximum gross takeoff weight
3Xtrim take their company name from a double entendre, as they refer to their designs being "triple trimmed" (or more exactly "triple-tested") during the design, prototype and production stages and also that the aircraft is designed for "extreme conditions". In English the company name is pronounced "Three-Extreme".
Former SZD sailplane engineer Adam Kurbiel designed the predecessor of 3X55, the EOL-VLA, to conform to European JAR-VLA rules. That plane was modified through the years to meet Canadian Advanced Ultralight and US Light Sport Aircraft rules. The 3X47 version is specifically for the European market to meet those standards.
The designation 3X55 means "3Xtrim Aircraft – 550 kg gross weight" while the 3X47 refers to its 470 kg gross weight.
The European versions feature extensive structural use of carbon fibre to achieve lightness, while the 3X55 is predominantly of fibreglass construction. Otherwise the two aircraft are similar in appearance and performance.
The 3X55 first flew in 1996 and by the summer of 2006 about 60 aircraft of both types had been produced.
The fuselage and vertical tail of the 3X55 is a one-piece structure made from fibreglass. The firewall is a Fiberfrax ceramic/aluminium sandwich.
The cockpit is 47.5 inches (1.21 m) wide at the elbows. Crew access is via a door on each side of the cockpit that hinges upwards and is supported by a gas strut.
The control sticks are located conventionally in front of each seat. The standard throttle arrangement is one panel-mounted centre throttle, but a second throttle located on the left side of the panel is optional, allowing the left-seat pilot to fly with either hand on the throttle or stick.
