Joby Aviation Monarch (defunct)

Monarch Personal Air Vehicle (defunct)
Joby Aviation
Santa Cruz, California, USA

Founded in 2009 by JoeBen Bevirt, Joby Aviation is a venture-backed startup aerospace company located in Santa Cruz and San Carlos, California (USA), that is developing and will manufacture piloted all-electric vertical takeoff and landing (eVTOL) aircraft for fast, quiet, and affordable air taxi services.

JoeBen Bevirt is a prolific inventor creating a diverse range of commodities, from making useful consumer products, to LED lights, electric motors, eVTOL aircraft and more. Joby Aviation's first design for an electric vertical takeoff and landing (eVTOL) aircraft was named the Monarch Personal Air Vehicle (PAV).

The pictures and a video of the Monarch eVTOL aircraft was first revealed to the public at the Electric Aircraft Symposium in Santa Rosa, California, USA on April 29, 2011. At the time, there was talk of a purchase price of less than $30,000.00 USD for the Monarch aircraft, its low estimated price was due to the low cost of electric motors, propellers, navigation equipment and controllers, that is, if the aircraft was put into mass production.

The Joby Monarch. The first eVTOL aircraft designed by Joby Aviation.

The Monarch was a one (1) person eVTOL aircraft with eight (8) propellers and motors mounted to a main pivoting 37 ft (11 m) wing and could cruise at 100 mph (101 km/h) with a range of 100 miles (101 km). The aircraft takes off and lands with the main wing pivoted to the vertical position and the wing is then tilted to a horizontal position for forward flight.

Four (4) propellers/motors are distributed on the top of the main wing mounted on struts and four (4) propellers/motors are distributed along the bottom of the wing, again mounted with struts. It has a bubble canopy for excellent aerial views and has one (1) main retractable landing wheel under the pilot's seat, with two (2) small support wheels under each side of the main wing and one (1) retractable rear taildragger skid.

The fuselage for the Monarch eVTOL prototype was built but after more analysis of the design was made, the building of the prototype stopped and the Monarch never flew. Joby Aviation went on and built the Joby Lotus (now defunct), the Joby S2 (now defunct) and the Joby S4 production prototype eVTOL aircraft.

Joby Aviation will offer their Joby S4 aircraft as a ride share service for Uber and/or be in a partnership with other ride share companies with Uber. Joby Aviation has stated on their website, they have become the first partner in Uber’s Elevate initiative with a committed timetable (for 2023) to deploy air taxi services.
