The Avid Aircraft Magnum is an American two-seat homebuilt cabin monoplane which was designed and sold as kits by Avid Aircraft of Caldwell, Idaho.

Design and development

The Magnum is a high-wing strut-braced monoplane with a welded steel tube fuselage, the wings have aluminium spars and wooden ribs covered with Ceconite.^[1] The Magnum was sold without an engine and was designed for a range of Lycoming engines from 115 to 180 hp (86 to 134 kW), for example the Lycoming O-235, O-320 or the O-360.^[1] The enclosed cabin has side-by-side configuration seating for two with an option for an additional seat in the baggage area for two children or a small adult.^[1] It has a fixed conventional landing gear with a tailwheel and some are fitted with floats.^[1]

By 2010 the aircraft was back in production by the Airdale Flyer Company of Rhinelander, Wisconsin. The Airdale version includes some modifications, including enlarged landing gear, plus optional tricycle landing gear.^[2][3]
