Rebuild of the Sand Viper. Although not being a direct derivate, it's named Sand Viper Mk.II, as it replaces the older two-seat version. Tests found out that a second seat isn't a good idea, due to the immense mass increasement caused by the longer fuselage. Another point was that the passenger often died in dogfights after a few hits. For better flight characteristics and a lower chance of being scouted by enemy radars, the body was shortened.
Not the best build of mine, I know. Also not happy with the photo quality.
