Balsa USA 1/4 Scale S.P.A.D. 13 Kit No. 404

French World War I Biplane Fighter

By far the most highly detailed model to date in our popular line of 1/4 scale World War I models! Favored by American aces for its strength, power and speed the S.P.A.D. 13 was something to be reckoned with by its adversaries. Balsa USA’s S.P.A.D. 13 lives up to the reputation set by the original back in 1918!
