SeaMaster

Built from plans, this 48-inch-span model has foam-core wings, a Depron fuselage, and balsa-and-ply wing saddles and wing attachment points. After he covered the fuselage with Eze-Kote, a water-based finishing resin, he glassed the bottom with fiberglass and epoxy resin. The 2.5-pound model is powered by a 300-watt motor on a 3S 2200mAh LiPo.
