This is an ultra rare and superb kit of the P-51 Mustang. This kit was called quick build because of the molded ABS fusleage sides and the foam wing, making it a relatively easy to build Mustang. This plane can be set up for flaps and retracts (fixed gear included) and is a fantastic flying plane. The plane has a wingspan of 64 inches and 648 square inches of wing area. Designed around a 60 2 stroke it is a natural for a four stroke engine. As a bonus appropriate wheels and spinner are included in the kit. Excellent instructions are a highlight of any SIG kit. Also included are decals to match the box picture of the plane.
