B & B Aircraft Sandpiper

Single-seat single-engined high-wing mono-plane with conventional three-axis control. Inverted V-tail. Pitch/yaw control by elevon; control inputs through stick for pitch/roll and pedals for yaw. Integrated flaps and ailerons. Wing braced from below by struts; wing profile; NASA high-lift airfoil double-surface. Undercar-riage has three wheels in tricycle formation: spring steel, inflatable tires. Aluminium-tube framework, without pod. Engine mounted below wing driving pusher propeller.


Two struts either side of the pilot support the high wing, and there are no rigging wires, the absence of a kingpost making for a very clean design. Wings are foam blanks fitted to aluminum spars and heat-shrink covered with Dacron. The maker says that 3 inch (7.6 cm) square-section tubing is used for the structure, which as a result can handle 9 g. It has a single large-diameter vertical wing support between pilot and engine.
