Designed by David Wigley, the Westland Wyvern is a 1/5-scale Competition-level scale model. It features custom-made fully-function shock-absorbing retractable landing gear and functional fowler flaps. The power system is also custom made consisting of a BME 100cc twin cylinder gas engine and a unique home made contra-rotating propeller arrangement. The rear 3-bladed prop is engine driven while the front prop windmills to duplicate the sight and sound of the original without the need of a heavy, complicated gear drive unit.
