Flyt Aerospace was founded in June 2013 in Cupertino, California, USA by Ansel Misfeldt. In ninth grade, Misfeldt dreamed he could fly to school each morning so he could sleep in longer in the mornings. He studied at the University of Southern California (Los Angeles, California, USA) obtaining a business degree in 2010 while taking courses in mechanical engineering and in material science at the same time. He also studied some aerospace engineering on his own time while at the university. All the while, he continued his dream of creating a small one person flying machine and had made hundreds of drawings and sketches of aircraft up to 2013. The company is currently seeking investors.

Misfeldt quit his job in early 2013, started his own aerospace company and has focused on building his own personal flying eVTOL aircraft and small drones since then. Misfeldt reveals that creating a personal flying machine is a very difficult and a complex problem. He has designed, manufactured and flown at least nine different prototypes. Two of his early prototypes were vertical takeoff and landing (VTOL) multicopter aircraft powered by gasoline engines using mechanical gears, shafts and pulleys to transfer the power to the propellers. The remainder of his prototypes are electric VTOL (or eVTOL) multicopter aircraft made with the ultimate goal of creating a personal aircraft for advanced air mobility (AAM).

Flyt Aerospace is now in the business of selling a small eVTOL drone called the Defender X4E with a maximum payload of 5 lb (2.27 kg) with over one hour endurance that are sold to government entities and the military. The Defender X4E has been designed to allow it to have many options so the drone can be adapted to the customer's requirements. Recently, Misfledt has partnered with the Land Rotor, based in Florida, USA and is creating passenger eVTOL aircraft for Land Rotor, for advanced air mobility.

Mark IV one passenger eVTOL defunct prototype multicopter aircraft
The Mark IV is a uncrewed remote controlled eVTOL defunct prototype multicopter test bed aircraft. There was no pilot's seat on the aircraft. The Mark IV actually flew about 50 times, according to the inventor. Even though the aircraft had no pilot's seat, the aircraft could carry various payloads of up to 200 lb (91 kg).

There is a hypothetical cruise speed for the Mark IV multicopter but because this is a prototype, it is only flown close to the ground and in a small area for testing purposes. The aircraft was never intended to be flown at what would be considered its cruise speed. The Mark IV had eight propellers, eight electric motors and 32 batteries to power the multicopter. The batteries weighed approximately 60 lb (27 kg).

The empty weight of the multicopter aircraft is estimated at 70 lb (32 kg), has an empty weight with batteries of approximately 130 lb (59 kg), has a maximum payload weight of 200 lb (91 kg) and has an intended maximum takeoff weight of 330 lb (150 kg). The fuselage was a flat octagon shaped open-framed structure with the each propeller on each outside vertex of the octagon beams. The fuselage was made from 4130 chrome steel and landed on the bottom of the fuselage structure.

The Mark IV became the Flyt 16 multicopter aircraft. For the Flyt 16 model, an opened-framed base was made with a pilot's seat and controls. Then on top of the pilot's cockpit was two Mark IV multicopter airframes mounted on top of each other.

Specifications:

  • Aircraft type: eVTOL defunct prototype multicopter drone
  • Piloting: Remote control piloting only, no pilot on board, no pilot seat
  • Cruise speed: There is a hypothetical cruise speed for the multicopter but because this is a prototype and is only flown close to the ground for testing purposes, the aircraft was never intended to be flown at what would be considered its cruise speed
  • Flight time: 8 minutes
  • Empty weight (estimated): 70 lb (32 kg)
  • Empty weight with batteries: 130 lb (59 kg)
  • Maximum payload weight: 200 lb (91 kg)
  • Maximum takeoff weight: 330 lb (150 kg)
  • Propellers: 8 propellers
  • Electric motors: 8 electric motors
  • Power source: 32 batteries (60 lb/27 kg)
  • Fuselage: Octagon open-framed fuselage made from 4130 chrome steel
  • Cockpit: There is no cockpit, remote controlled
  • Landing gear: Lands on the bottom of the fuselage structure
  • Safety features: Distributed Electric Propulsion (DEP), provides safety through redundancy for its passengers and/or cargo. DEP means having multiple propellers (or ducted fans) and motors on the aircraft so if one or more propellers (ducted fans) or motors fail, the other working propellers (or ducted fans) and motors can safely land the aircraft. There are also redundancies of critical components in the sub-systems of the aircraft.
