Seagull Models Ultimate Bip .46-55cu 2 Stroke RC Plane Kit - SEA212US

The Seagull Models Ultimate Bip is a nitro-powered RC biplane kit designed for intermediate to advanced pilots, built around a .46–.55 2-stroke engine (or equivalent 4-stroke). With a 109cm (43in) wingspan and an overall length of 113.7cm (44.8in), this is a substantial biplane that rewards pilots who already have some fixed-wing RC experience. The SEA212US is sold as a kit, so you'll be doing the assembly yourself — a rewarding build that results in a capable and visually striking RC aircraft.
