The company was founded in 2009 in Australia to research various technologies for electric motors. In 2017, it developed a motor that became their prototype and led to pivoting the company to focus on Electric Aviation and move its headquarters to Redmond, Washington.[ citation needed ] The magni5, its original prototype electric motor, was developed in 2017.[ citation needed ]
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 density. The magni5 competes with the 260 kW (350 hp), 50 kg (110 lb) Siemens SP260D for the Extra 330LE. [2]
By September 2018, a 260 kW (350 hp) electric motor with a propeller had been tested on a Cessna iron bird. The 560 kW (750 hp) Caravan was expected to fly by the fall of 2019 and by 2022 magniX estimates electric aircraft could fly up to 800 and 1,610 km (500 and 1,000 mi) by 2024. [3] The motor ran on a test dynamometer for 1,000 hours. The iron bird is a Caravan forward fuselage used as a test bed, with the usual PT6 turboprop engine replaced by an electric motor, inverter and a liquid-cooling system, including radiators, driving a Cessna 206 propeller. The production motor will produce 280 kW (380 hp) at 1,900 rpm, down from the test motor's 2,500 rpm, allowing the installation of the propeller without a reduction gearbox. [4]
By April 2019, the magni250 280 kW (375 hp) was offered for the Eviation Alice as a second power option after Siemens 260 kW motors, as magniX had accumulated over 1,500 hours of ground tests in Redmond and Australia. [1]
In July 2022, magniX announced the development of the magniX EPUs (Electric Propulsion Units), [5] which are aimed at powering larger commercial aircraft with over 1 MW of power, signaling a significant advancement in electric aviation technology.
By then, magniX partnered with Harbour Air to electrify its entire fleet: the first converted aircraft was to be a DHC-2 Beaver serving as the test prototype for the magniX motor, energy storage, and control systems. [6] On 10 December 2019, the eBeaver flew for the first time. [7] Low energy density but proven lithium-ion batteries filled the cabin and took the prototype to its maximum gross weight to provide enough energy for a 15 min flight with a 25 min reserve. [8]
The magniX magni500 electric motor used in the Harbour Air electric de Havilland Canada Beaver weighs 135 kg (297 lb) and develops 560 kW (750 shp) [9] In contrast, the Pratt & Whitney R-985 Wasp Junior SB it is replacing has a dry weight of 290 kg (640 lb), not including oil, and produces 400 bhp (300 kW), more than halving the weight, while nearly doubling the power –a saving in this case that can be transferred toward carrying the difference in additional batteries.[ original research? ]
The first flight of the modified Cessna 208B Grand Caravan was completed at Grant County International Airport on 28 May 2020. [10] The eCaravan is powered by a 560 kW (750 hp) motor and a 1 t (2,200 lb), 750V lithium-ion battery. Its 30 min first flight consumed $6 worth of electricity, needing 30-40 min of charging. The magni500-powered variant can fly 160 km (100 mi) with 4-5 passengers while keeping reserve power, and aims for a certification by the end of 2021, hoping to operate 160-kilometre (100 mi) flights with a full load of nine passengers with better batteries. [11]
In December 2020, CEO Roei Ganzarski told an interviewer [12] that the company was consolidating its operations at Everett, Washington, and had shut their Australian site on the Gold Coast earlier in the year. In January 2021 the company formally announced that they will be moving their headquarters from Redmond to Everett, with plans to relocate all of their Australia operations there as well. [13]

The Cessna 172 Skyhawk is an American four-seat, single-engine, high wing, fixed-wing aircraft made by the Cessna Aircraft Company. First flown in 1955, more 172s have been built than any other aircraft. It was developed from the 1948 Cessna 170 but with tricycle landing gear rather than conventional landing gear. The Skyhawk name was originally used for a trim package, but was later applied to all standard-production 172 aircraft, while some upgraded versions were marketed as the Cutlass, Powermatic, and Hawk XP. The aircraft was also produced under license in France by Reims Aviation, which marketed upgraded versions as the Reims Rocket.
A regional airliner or a feeder liner is a small airliner that is designed to fly up to 100 passengers on short-haul flights, usually feeding larger carriers' airline hubs from small markets. This class of airliners is typically flown by the regional airlines that are either contracted by or subsidiaries of the larger airlines. Regional airliners are used for short trips between smaller towns or from a larger city to a smaller city. Feeder liner, commuter, and local service are all alternative terms for the same class of flight operations.
The Cessna 208 Caravan is a utility aircraft produced by Cessna. The project was commenced on November 20, 1981, and the prototype first flew on December 9, 1982. The production model was certified by the FAA in October 1984 and its Cargomaster freighter variant was developed for FedEx. The 4 ft (1.2 m) longer 208B Super Cargomaster first flew in 1986 and was developed into the passenger 208B Grand Caravan.
Harbour Air Seaplanes is a scheduled floatplane service, tour and charter airline based in Richmond, British Columbia, Canada. The predominantly seaplane airline specializes in routes between Vancouver, Nanaimo, Victoria, Sechelt, Comox, Whistler and the Gulf Islands, primarily with de Havilland Canada floatplanes. Harbour Air operates de Havilland Beavers, Otters and Twin Otters.
The Cessna Skymaster is an American twin-engine civil utility aircraft built in a push-pull configuration. Its engines are mounted in the nose and rear of its pod-style fuselage. Twin booms extend aft of the wings to the vertical stabilizers, with the rear engine between them. The horizontal stabilizer is aft of the pusher propeller, mounted between and connecting the two booms. The combined tractor and pusher engines produce centerline thrust and a unique sound. The Cessna O-2 Skymaster is a military version of the Cessna Model 337 Super Skymaster.
The PAC P-750 XSTOL, is a utility aircraft of conventional all-metal low-wing monoplane design, with fixed tricycle undercarriage. Combining the engine and wings of the PAC Cresco with a new larger fuselage and modified tail, all versions to date have been powered by a 750 hp (560 kW) Pratt & Whitney Canada PT6 turboprop. It is designed and manufactured in Hamilton, New Zealand, by Pacific Aerospace Limited.
The aircraft diesel engine or aero diesel is a diesel-powered aircraft engine. They were used in airships and tried in aircraft in the late 1920s and 1930s, but were never widely adopted until recently. Their main advantages are their excellent specific fuel consumption, the reduced flammability and somewhat higher density of their fuel, but these have been outweighed by a combination of inherent disadvantages compared to gasoline-fueled or turboprop engines. The ever-rising cost of avgas and doubts about its future availability have spurred a resurgence in aircraft diesel engine production in the early 2010s.
An electric aircraft is an aircraft powered by electricity. Electric aircraft are seen as a way to reduce the environmental effects of aviation, providing zero emissions and quieter flights. Electricity may be supplied by a variety of methods, the most common being batteries. Most have electric motors driving propellers or turbines.
The Dornier Do 14 was a prototype seaplane, developed by Dornier Flugzeugwerke with backing from the Luftwaffe for experimental propulsion studies. The aircraft was similar to the Dornier Do 12. Only one Dornier Do 14 was constructed for testing, the aircraft registered as "D-AGON", after test flights during 1936, the aircraft engines were subsequently dismantled in 1937. The prototype aircraft was finally scrapped in 1939.

A hybrid electric aircraft is an aircraft with a hybrid electric powertrain. As the energy density of lithium-ion batteries is much lower than aviation fuel, a hybrid electric powertrain may effectively increase flight range compared to pure electric aircraft. By May 2018, there were over 30 hybrid electric aircraft projects, and short-haul hybrid-electric airliners were envisioned from 2032.
