The Plumb BGP-1 is a British single-seat homebuilt biplane developed by Barry Plumb.
The aircraft is patterned after the Pitts Special and is made predominantly from wood. The first example of Plumb's biplane was built between 1975 and 1986 and is on a Popular Flying Association (now Light Aircraft Association) permit to fly.[1] [2]
The aircraft was originally powered by a Volkswagen 1834 engine but now uses a Jabiru 2200A model[3]
A second example, was finished in 2015 and uses a Volkswagen 1834 engine.
