Bedson Resurgam

Mk.II


Designed by Gordon Bedson in Australia, the Resurgam is a strut braced high wing pusher, with a fully enclosed cockpit. A true home builders aircraft, the builder has the option of building from the plans up or by purchasing pre-molded fibre glass components and the manufactured spar, ribs and undercarriage, by which he can almost half construction time. The Resurgam has been updated and improved over the years.


The Resurgam was originally designed in 1948 to accommodate the JAP engine. A single-seat single-engined high-wing monoplane with conventional three-axis control. Wing has unswept leading and trailing edges, and constant chord; conventional tail. Pitch control by elevator on tail; yaw control by fin-mounted rudder; roll control by 58% -span spoilers (half-span ailerons optional); control inputs through stick for pitch/rod and pedals for yaw. Wing braced from below by struts; wing profile 4415; 100% double-surface. Undercarriage has three wheels in tricycle formation; suspension type wood/glass-fibre suspension on main wheels. Push-right go-right nosewheel steering connected to yaw control. Wood/aluminium-tube fuselage, partially enclosed. Engine mounted at wing height driving pusher propeller.


The front half of the two-part structure is made of spruce and plywood, while the other half consists of a triangulated structure of aluminium-alloy tubes, which supports the engine and extends rearwards to form the empennage. The centre section of the wing is attached to the front fuselage, while the remainder of the wings are attached by six pip pins to facilitate derigging, which can be achieved without breaking any control cables. Wing design consists of a single spruce and plywood spar, to which plywood-and-foam composite ribs are attached by epoxy, with the joints strengthened by use of glassfibre. Foam is used for leading and trailing edges, the former being glassfibre covered and the latter by plywood.


An unusual feature of the Resurgam is that it is designed to accommodate two different roll-control systems. Spoilers are the normal fitment, operated by an aluminium-alloy torque tube which spring loads the spoiler into the closed position, but as you can see from our picture, ailerons can be incorporated instead, operated by the same torque tubes.


In the 1982 London-Paris, when a Konig-engined Resurgam tied with the Huntair Pathfinder as winner of the speed event. The Konig SC430 is a popular fitment to this aircraft, the main alternative being the Skylark MkII.


The Mk.1 and Mk.2 differ in rear fuselage construction with the Mk.2 having a single tube boom.
