Design and development

The MA-5 Charger was designed and developed by Ed Marquart with the first prototype being built and flown by Daniel W. Fielder Jr. at Flabob Airport. It is an all-new design based around Marquart's single place homebuilt biplane, the MA-4. The aircraft was designed to perform mild aerobatics. Marquart sold plans for scratch building the aircraft, no kits were manufactured.[1] For a number of years, Ken Brock offered kits of the metal brackets utilized in the construction of the Charger's wings and fuselage.

The aircraft uses a welded steel tube fuselage with doped aircraft fabric covering. The wings use wooden spars and ribs. The biplane uses conventional landing gear and has two tandem open cockpits. The wings are constant chord and swept 10 degrees.[2]

The first prototype took seven years to build.

Since Ed Marquart's death in 2007,[3] the plans have been placed in the public domain, and are available as free PDF files via the Marquart Charger MA-5 website, marquartcharger.org, or the Charger groups on either Facebook or groups.io (formerly Yahoo).

Operational history

In 1982, Jim Smith's Marquart Charger won Grand Champion Plans-built Aircraft at the EAA AirVenture Oshkosh airshow.[4]

In 1987, Remo Galeazzi's Marquart Charger won Grand Champion Plans-built Aircraft at the EAA AirVenture Oshkosh airshow.[5]
