The Isaacs Spitfire is a single seat homebuilt sporting aircraft design created by John O. Isaacs, a former Supermarine employee and retired schoolmaster and designer of the Isaacs Fury, as a 6/10th scale replica of a Supermarine Spitfire. Its first flight was on 5 May 1975.
As per the original Spitfire, the Isaacs Spitfire was a cantilever low-wing monoplane of semi-elliptical planform. The twin spar wing was built in one piece, mainly of spruce with birch plywood skin. The fuselage was of identical construction. The landing gear is fixed and included a tailwheel.
Plans are available for sale to home constructors.
