The most common ducted fan arrangement used in full-sized aircraft is a turbofan engine, where the power to turn the fan is provided by a gas turbine. High bypass ratio turbofan engines are used on nearly all civilian airliners , while military fighters usually make use of the better high-speed performance of a low bypass ratio turbofan with a ...
Of much less complexity are the types of RC jet aircraft that actually use an electric motor-driven ducted fan instead to power the aircraft. So called "EDF" models can be of much smaller size, and only need the same electronic speed controller and rechargeable battery technology as propeller-driven RC electric powered aircraft use.

The aircraft has twin booms with twin rudders and a high-mounted tailplane. It is powered by a Lycoming flat-six normally-aspirated engine situated behind the cabin and driving a fixed pitch ducted fan. Due to the ducted fan, the aircraft is exceptionally quiet. The aircraft has a fixed tricycle undercarriage with the nosewheel offset to the left.
The pilot sits in a recumbent position in a streamlined nacelle. The engine is mounted at the rear and powers a three-bladed ducted fan. There is no empennage. The undercarriage consists of two non-retractable wheels arranged in tandem, with balancer wheels located under the wingtips.
Nitro engines for models can turn in excess of 50,000 RPM. Typical operating rpm for sport model aircraft engines is 10,000–14,000 RPM. For radio control (RC) boats and ducted fan aircraft engines, 20,000–25,000 is the usual range, and for cars RPM in the range of 25,000–37,000 is common. With this much movement, a lot of frictional heat ...
A pusher aircraft is a type of aircraft using propellers placed behind the engines and may be classified according to engine/propeller location and drive as well as the lifting surfaces layout (conventional or 3 surface, canard, joined wing, tailless and rotorcraft), Some aircraft have a Push-pull configuration with both tractor and pusher engines.
This fan-in-tube design has been adopted successfully for electric-powered jets while glow engine powered ducted-fan aircraft are now rare. Small jet turbine engines are now used in hobbyist models that resemble simplified versions of the turbojet engines found on commercial aircraft, but are not scaled-down as Reynolds numbers come into play.
