Spektrum S665 High Torque Steel Gear 25T Servo Fits Big Rock Kraton Notorious 6S LOSI 8ight XE XTE RTR - SPMS665

The Spektrum SPMS665 S665 is a high-torque, steel gear servo designed as a direct-fit replacement or performance upgrade for the ARRMA Big Rock 6S, Kraton 6S, Notorious 6S, and the Losi 8ight XE and 8ight XTE RTR. Built around a 25T output spline, this servo is engineered to handle the steering and throttle demands of large-scale 6S-powered RC vehicles, where standard servos are often pushed beyond their limits. The steel gear train gives it the durability to absorb the shocks and loads generated by heavy bashers and race trucks running at full 6S power.

Key Features

• High-torque output rated for demanding 6S applications where steering precision and holding power matter
• Steel gear train provides significantly greater resistance to gear stripping compared to plastic or hybrid alternatives
• 25T spline output is a direct match for the servo horn specifications used on compatible ARRMA and Losi platforms
• Direct-fit design means no modifications are required for installation in the listed ARRMA 6S and Losi 8ight models
