Tissue and dope over the balsa skin and sanded smooth.
Painted in a kinda copy of my old Airfix 24th Hurricane.
Powered by a speed 600 off an 8.4v Nicad pack. the original plan called for one servo to handle a plastic pushrod for ailerons,
i dumped this and mounted a micro-servo in each wing. One mini-servo for the elevators and ditto for the rudder.
Engine power controlled by a Graupner 3 stage electronic speed control.
