Balsa USA 1/4 Scale S.E.5A Kit No. 412

British WorldWar I Biplane Fighter

Unquestionably one of the most successful Allied single seat fighters of World War I, the S.E.5a was a superb aircraft. Designed to seek out trouble and meet it head on, while its stable, easy flying qualities made it a favourite among pilots who flew it. Now Balsa USA has reproduced the S.E.5a’s same great flying qualities in an easy to build 1/4 scale model. Shown here in the colours of the American 25th Aero squadron.
