In June 2018, magniX publicly stated plans to fly an electric Cessna 208 Caravan with a 540 kW (720 hp) motor for up to an hour, by August 2019. [2] By then, the company's magni5 electric motor could produce 265–300 kW (355–402 hp) peak at 2,500 rpm at 95% efficiency with a 53 kg (117 lb) dry mass motor, having a 5 kW/kg (2.3 kW/lb) power ...
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 current heats the platinum filament, causing it to glow red hot, hence the name. The engine is then spun from the outside using a manual crank, built-in rope-based recoil starter, spring-loaded motor or purpose-built electric motor, or by hand, to introduce fuel to the chamber. Once the fuel has ignited and the engine is running, the ...
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.
In 1969, American Jet Industries began work on a turboprop-powered conversion of the Cessna 402, named the Turbo Star 402, using Allison 250-B17 engines. [5] The prototype flew on 10 June 1970. [ 5 ] Further modifications providing increased fuel capacity, higher gross weight, and lower minimum control speed were carried out in 1974 and the ...
The 20 and 23 meter variants can be equipped with a 42-kW electric motor and SAFT VL 41M lithium-ion batteries. The EM 42 is a fixed-shaft brushless DC electric motor running at 190-288 V, and drawing up to 160 A, the 42 kW motor can deliver up to 216 N.m of torque over a speed range of 160-1600 RPM with a total efficiency of 90%.
The Eviation Alice is an electric aircraft designed to accommodate nine passengers and two crew members. First developed in Israel, [3] its construction incorporates 95% composite material, is powered by two electric motors, and has a T-tail. The prototype first flew on 27 September 2022. [4]
The power systems are normally only used for short periods to launch thermal soarers, motor runs of 30 seconds are typical with timer or height limiting onboard electronics cutting power automatically during competitions. [6] Electric gliders use propellers which fold inwards when the power source is cut off during flight. This provides the ...
