Moebius Battlestar Galactica MK VII Viper Model Kit (172 Scale) Capable of atmospheric flight the Mark VII is the front-line variant of the Viper design retaining the Mark IIs general layout but adding fully integrated avionics that provide superior battle management and flight information for the pilot Ironically it is this incorporation of new integrated systems that prevents the majority of Mark VIIs from being effective during the Cylon attack as with the majority of Colonial Fleet the Mark VIIs suffer fatal computer system failures on contact with Cylon forces
