Mark Devino (1721 Fernwood Ln., Algonquin IL 60102; E-mail: devino@elnet.com) built this Sig Hog biplane from a kit and powered it with an O.S. .91 four-stroke engine. He moved the landing gear forward 1/4 inch and put some right thrust in the engine mount. Other than those slight modifications, the model is stock. Mark wrote, “The airplane flies nicely on the .91; it’s a superb match!”

The airplane is covered in MonoKote and most of the trim was cut from MonoKote, although some Vinylwrite lettering was used. The wheel pants and the landing-gear strut are painted.
