Multiplex Modellsport

Lore & Background

Multiplex's aircraft lineup ranges from small powered gliders like the Cularis to pusher-prop jets such as the FunJET, electric sportliners like the Blizzard, and the company's largest model, the Mentor—a discontinued trainer resembling a Cessna 180, large and powerful enough to serve as a glider tug. The FunJET, introduced in 2007 as a replacement for the TwinJET, became a popular subject for modification, with heavily modified examples exceeding 130 MPH (210 km/h). In 2010, the company introduced the FunJET Ultra, which addressed problems in such modifications with denser Elapor, improved aerodynamics, and an updated motor mount. Also in 2010, Multiplex entered the helicopter market with the Funcopter, featuring an Elapor fuselage and a direct drive rotor system that eliminated drive gears and one-way bearings.

Reader's Guide

Multiplex's use of Elapor foam distinguishes its models in the hobby-grade RC market, offering durability and ease of repair that contrasts with traditional balsa or EPS foam construction. The company's aircraft, from the small Cularis glider to the large Mentor trainer, cover a broad range of flying styles. The FunJET line, particularly the original model and its Ultra variant, demonstrates the company's responsiveness to the modification community, with the Ultra incorporating structural and aerodynamic improvements for high-speed performance. The Funcopter helicopter introduced a novel direct-drive rotor system, simplifying the drivetrain. Multiplex also produces the RoyalPRO line of radios, servos, and electronic speed controls for both air and surface use, competing with brands such as Spektrum RC, Futaba, and Graupner.

Did You Know?

• Multiplex's Elapor foam cannot be bonded with two-part epoxy or 'foam safe' cyanoacrylate adhesives; only ordinary hobby-grade cyanoacrylate works.
• The Mentor trainer is packed with parts to allow its use as a glider tug.
• The FunJET Ultra eliminated the simulated wing tanks found on the original FunJET.
• The Funcopter helicopter uses a direct drive rotor system, eliminating drive gears and one-way bearings.
