Fly BabyBiplane

The Fly Baby can be built as a biplane as well as a monoplane. The two monoplane wing panels are replaced by four smaller ones, plus a centre section for the top wing. The aircraft can be switched back and forth between versions in about an hour, but it does take a helper. The biplane, while cool in concept, doesn't really offer too much. It's slower, and the wings don't fold. Still, its swept-back upper wings make it look a bit like a Bucker or Tiger Moth in the air, so if you'd really rather have a biplane, the Fly Baby would do the trick.
