The Multiplex TwinJet — the ELAPOR-foam twin-EDF model that brought entry-level jet flying within reach of intermediate pilots.
The TwinJet is part of the Multiplex Modellsport jet-foamy product line, a German RC manufacturer that built its reputation on durable ELAPOR-foam construction and ready-to-fly convenience. The TwinJet was one of the early ELAPOR-foam twin-engine EDF (electric ducted fan) models, designed to give pilots an entry-level introduction to multi-engine jet flying without the expense or complexity of a balsa or composite scale jet.
The ELAPOR foam construction that Multiplex developed for its full product line is the foundation of the TwinJet's handling character. ELAPOR is a moulded particle foam that is tougher than traditional EPP and repairable with ordinary cyanoacrylate (CA) glue. The result is an airframe that can take a beating — hard contacts with grass, the occasional fence, the inevitable misjudged jet landings of a learning pilot — and come back together on a workbench in twenty minutes. Twin EDF units in semi-blended nacelles, a swept main wing, and a generally clean modern-jet silhouette gave the TwinJet the aesthetic of a proper jet without the cost or skill demands of a true scale subject.
The bigger picture is the foam EDF category itself. Whether Multiplex TwinJet, Funjet, or any of dozens of similar designs from competing manufacturers, foam EDF jets have become the modern entry point into the jet category — replacing the old "build a glow-powered ducted-fan" tradition with airframes that go from box to flying field in a single afternoon.
A friendly entry into multi-engine jet flying. The TwinJet's twin-EDF layout gives a sense of jet flight character without the demanding approach speeds of a true scale jet. Use it as the natural step from a sport foamy into the jet category.
