The SIG Ultimate Fun Fly biplane was modeled after one of the most recognized airplanes on the air show circuit today - the Ultimate 10-300. This biplane has captured the imagination of many modelers with its simple, yet distinctive, looks and outstanding flight performance. Following in the footsteps of the SIG Fazer, the SIG Ultimate Fun Fly biplane is an easy to build, all wood design with a profile fuselage and built-up balsa wings. CAD drawn plans, computer generated tooling, and laser cutting provide the modeler with parts that fit precisely the way they were intended. The flight performance of the Ultimate Fun Fly is awesome! Super tight loops, lightning fast rools, flat spins, knife edge flight, and hovering are just a few of the maneuvers that this model can perform.
