Glow plug engines combined with ducted-fan units were the first achievable means of modeling a scaled-size jet aircraft. Despite the introduction of model-scale turbojet engines, electric-powered ducted fans remain popular on smaller, lower-cost model aircraft. Some electric-powered ducted fan airplanes can reach speeds of more than 320km/h ...
The Rotapower engines used in the prototypes are being developed by an affiliate Moller company called Freedom Motors. [6] Each power unit comprises a Wankel rotary engine directly driving a ducted fan. [7] [8] The housing is lined with Kevlar to contain the fan blades in the event of failure. [7]
The fans were generally powered by 2 stroke engines at high RPM. They generally had 0.40 to 0.90 cu in (6.6 to 14.7 cc) displacements, but some were as small as 0.049 cu in (0.80 cc). This fan-in-tube design has been adopted successfully for electric-powered jets while glow engine powered ducted-fan aircraft are now rare.
A radio-controlled aircraft (often called RC aircraft or RC plane) is a small flying machine that is radio controlled by an operator on the ground using a hand-held radio transmitter. The transmitter continuously communicates with a receiver within the craft that sends signals to servomechanisms (servos) which move the control surfaces based on ...

Four-stroke model engines have been made in sizes as small as 0.20 in3 (3.3 cc) for the smallest single-cylinder models, all the way up to 3.05 in3 (50 cc) for the largest size for single-cylinder units, with twin- and multi-cylinder engines on the market being as small as 10 cc for opposed-cylinder twins, while going somewhat larger in size ...

The RFB Fantrainer (or Fan Trainer) is a two-seat flight training aircraft which uses a mid-mounted ducted fan propulsion system. Developed and manufactured by German aircraft company Rhein-Flugzeugbau GmbH (RFB), it has been used by the Royal Thai Air Force. Development of the Fantrainer commenced during the 1970s.
