The Viper 3X is the next generation of the Blast series. The airframe is an extremely efficient F5D model that is designed to have the fastest straight line speed, and be the most efficient and hardest turning model in its class. For DS that means an extremely stable model, quick turns and fast on radar. The wing has a huge spar and 3X carbon in the skins. The wing feels like it is solid carbon! The fuse is designed with a larger diameter boom, which makes it even stronger than the blast as well as makes the push rod install very easy. The fuse is designed to fit plenty of ballast, and radio gear. It has a removable nose cone, so the model can be easily converted from a slope model to an electric.
