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 ...
The first flight of the E-Fan 2.0 was originally planned for 2017 and the E-Fan 4.0 for 2019. [1] A ducted fan on the E-Fan. The E-fan is of all-composite construction and is propelled by two ducted, variable-pitch fans spun by two electric motors totaling 60 kW of power. Ducting increases thrust while reducing noise, and having the fans ...
Many notable individuals in the 1960s through the 1990s and beyond created the landscape of modern RC modeling. These included many starting their own companies. The families of many of these individuals lost interest in continuing these businesses. The incoming supply of ARF planes from overseas made it hard to sell kits requiring assembly.
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 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 recent race between an electric plane and a car demonstrated the challenges of battery-powered flying, but this quest to reach an island in the North Sea underlines the potential, as well as the ...
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 Skycar has four such nacelles, each with two Rotapower engines mounted in tandem. All eight engines operate independently under computer control and, as demonstrated ...
