Building on engineering innovations seen in this popular jet model, ROCHOBBY(by FMS) has launched
a brand new 70mm EDF Super Viper onto the market!
In terms of appearance, the Super Viper has a scaled navy blue color scheme with bright yellow wingtips,
which highly distinguishes it for long distance viewing. The optimized fuselage shape decreases wind

extreme maneuvers.

standard PNP with options to add flap servos.
