3Xtrim 3X55 Trener

The 3X55 Trener (English: Trainer) and 3X47 Ultra are a family of ultralight civil 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 take-off 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”.
