✈️ The E-flite Viper 90mm EDF BNF Basic is a large radio-controlled jet that combines speed, precision, and ease of flight. Inspired by the full-scale Viper and developed from the famous Viper 70mm model, this 1.40 m wingspan model offers the smooth handling of a sport aircraft while maintaining the performance of a real jet. Its 90-mm, 12-blade EDF electric turbine, combined with a brushless 6S 1950Kv motor, enables it to reach a claimed speed of over 190 km/h, with excellent climb and aerobatic capabilities.
