This is the KO Propo 30101 "RSx Power H.C." High Torque Digital Racing Servo. The RSx servos are the end result after two years of R&D, in both on-road and off-road disciplines. The new servo line features the highest quality materials for increased strength, as well as new programming to take advantage of today’s current technology.

The 30101 is recommended for use on steering for 1/8th off-road truggy, throttle for 1/8th off-road buggy/truggy and throttle for 1/8th on-road.

RSx Features:

  • Internal
    • The servo gears are cut in house for the best Quality Control from “special Japanese aluminum” for superior hardness and wear. This aluminum is 30% lighter and 20% stronger then steel.
    • The servo amplifier and processor has been re-designed and optimized for direct 7.4V LiPo voltage, but will still operate when used with NiMH cells.
    • A new core-less motor has been developed specifically for high voltage applications to further enhance the use of the LiPo technology.
    • ICS programming and software will be available via PC or the RSx setting card.
  • External:
    • The middle case is a one-piece machined aluminum part so the gears and gear pins are held properly in place without any plastic insert that will wear out.
    • The H.C. (Hard Case) versions of the RSx include a machined upper case for maximum rigidity.
Specifications:
  • Voltage: 6V or 7.4V
  • Torque:
    • @6V: 362.9 oz-in (26.3 Kg-cm)
    • @7.4V: 436.1 oz-in (31.6 Kg-cm)
  • Speed:

Best servo I have owned and even seen in a 1/8 scale truggy. Super fast and the torque is amazing. I have (2) in my Eight-T 2.0...I constantly get compliments on just the casing alone.

The best servo you can buy hands down! I have the meta RSx high torque and the RZx Metal Response servos.
Will never buy any thing else. Highly recommend. High torque for steering and Response for throttle in my K cars.

Over past 10 years I've used Futaba & the newer 7.4v Hitec servos. The KO hard case servos have been flawless in my Serpent truggy. Highly recommend these servos.

This is my next servo that I am aiming for to be install to the throttle of my 1/8 buggy after 2 of the Savox 1268 gives way! Top notch Japanese made servo!
