The North American F-82 Twin Mustang was the last American piston-engine fighter ordered into production by the United States Air Force. Based on the P-51 Mustang, the F-82 was originally designed as a long-range escort fighter in World War II; however, the war ended well before the first production units were operational. Though the desription is for the F-82 Twin Mustang the plane I built was actually designed according to the prototype design by Kelly Johnson for the P-38 Lighting. Thanks for checking my plane out I hope you like it!
