While the Master had incorporated relatively advanced aerodynamic characteristics (intended to mimic frontline fighters) for a contemporary trainer aircraft, it used a conventional structure, comprising an oval-section fuselage covered by a plywood skin, featuring a semi-monocoque approach. Forward of the tandem cockpits, the nose is strengthened by a metal former that provides protection against nose-overs, a common occurrence amongst trainee pilots when flying aircraft with a 'taildragger' undercarriage. The tail section had an orthodox cantilever structure, the tailplane being mounted directly on top of the fuselage; according to "Flight", the tailplane's aerodynamics were designed to facilitate easy spin recovery. The Kestrel engine is mounted on tubular steel bearings which was designed to facilitate engine removal for ease of maintenance via the undoing of only four main bolts along with the connecting leads. Further maintenance savings were made via the engine's derating, allowing for a longer interval between overhauls.
