This 13-lb JetCat HP5 includes a jet engine (the round component on the bottom), but it is attached to a gearbox and the accessories needed to power a model helicopter. For example, it includes a centrifugal clutch that decouples the helicopter blades from the turbine, letting them stop turning while the engine is idling.
