Pegasus Quantum
The Pegasus Quantum is a British two-seat, ultralight trike that was designed and produced by Pegasus Aviation and later by P&M Aviation. The aircraft was supplied as a completed aircraft.

In the early 2000s Pegasus Aviation was merged with rival Mainair Sports into P&M Aviation, and production of the Quantum continued but shifted from the Pegasus plant in Marlborough, Wiltshire, to the Mainair factory in Rochdale. As the company rationalized the two aircraft lines, Quantum production ended. By 2012 the manufacturer indicated, "This aircraft is no longer in production...Full spares and support are still available and will remain so for the foreseeable future. Complete aircraft can still be manufactured but by special request only."

The Quantum was intended as an up-scale touring trike for long distance flying. It was designed to comply with the Fédération Aéronautique Internationale microlight category, including the category's maximum gross weight of . It is also certified to comply with UK BCAR Section "S" and German DULV microlight certification. The aircraft has a maximum gross weight of . It features a cable-braced hang glider-style high-wing, weight-shift controls, a two-seats-in-tandem, open cockpit, tricycle landing gear and a single engine in pusher configuration.

Its  span wing is supported by a single tube-type kingpost and uses an "A" frame control bar. The Quantum line includes a number of models that incorporate various options packages and engines.

Operational history
Quantums have been used for a number of record-setting flights, including the first microlight flight around the world, flown by Brian Milton and Keith Reynolds in the Quantum 912 Global Flyer between 14 March - 21 July 1998.

Milton explains why he chose the Quantum at the start of planning for the record-circling flight:

The Quantum was also flown by Simon Baker to win the World Microlight Championships.
