This is the JR 791 Hi-Torque Lo-Profile MG Retract Servo. The S791 is one of the most powerful retract servos in its class. With a full 260 oz/in of torque at 4.8V, it is plenty of servo for big scale applications. Its low profile case allows the S791 to fit almost anywhere and its metal gear train performs flawlessly, cycle after cycle. It also happens to be a "drop-in" fit for many of Hangar 9's retractable ARFs, like the .60, 1.50-size Mustangs or the .60-size Corsair.
