This model has been restored and was recently flown with a 50cc petrol engine. Engine was good for balance but not a good match. Now fitted with a Supertigre S3000 (G3250 stamped on crankcase) Engine started and tested but yet to be flown. Balance has been achieved with nominal weight. Comes with Bison pitts muffler and Supertigre muffler with box and alternative mount. As I am not a fan of retracts for heavy models, the plane has been setup with fixed undercarriage resembling the first Wirraway brought to Australia.
