Half-Scale RC Bristol Bulldog!

Designed, built and flown by Ian Turney-White,  the Bristol Bulldog features traditional model building methods and copied the full-size construction, using clear, knot-free Columbian pine instead of steel tubing.  Evostik exterior-grade glue was used throughout. The longerons were tapered towards the tail and the fronts were slit with a bandsaw and glued with a filler strip and clamped to a curved
piece of wood to match the side view contours. Diagonals were added and lots of corner gussets help reinforce the structural glue joints. The wings have dual built-up spar construction and the ribs are reinforced 3/16-inch hard balsa. The landing gear is 100% scale in design and function and the huge biplane is powered by a 425cc JPX 2-stroke twin-cylinder gas engine running with a Weslake target drone ignition system and a home-made 44×14 laminated beech propeller.

Flight Certified

To gain an exemption certificate, which allows you to fly a model weighing over 20Kg at public events, it’s necessary to complete a flight test program. Ken Wooten, the owner/operator of the airfield near Withernsea, East Yorkshire, was asked to witness the flights. The British Large Model Association operates on behalf of the Civil Aviation Authority and LMA Safety Officer John Townsend acted as the inspector.
