The KST DS125MG delivers industry-benchmark wing servo performance at a price that transforms what competitive glider flying costs. At just 10mm thin and 28g, it fits directly into the tightest glider wing bays — sharing the exact form factor of leading premium servos — while delivering zero-backlash control, a coreless motor, and hardened steel gears that meet 90% of top-tier performance standards for less than half the price. Whether you're chasing thermals in F3J, ripping the slope in F3F, or optimizing lift in F5J, the DS125MG delivers the precision and reliability that competition pilots expect.
Key Features
- Ultra-Slim 10mm Profile: Identical form factor to leading premium wing servos — installs directly into existing servo bays on F3F, F3B, F3J, and F5J gliders without modification.
- Zero Backlash Geartrain: Hardened steel gears with precision fit deliver crisp, play-free control authority for exact surface positioning.
- Coreless DC Motor: Fast, linear response with smooth travel and consistent centering across the full range of motion.
- Dual Ball Bearings: Dual-bearing output shaft support reduces friction, enhances centering accuracy, and extends service life under sustained aerodynamic loads.
- Full CNC Aluminum Casing: Precision-machined alloy housing ensures accurate wing bay fitment, structural rigidity, and effective heat management.
- Programmable & Soft Start: Configurable travel limits with soft-start protection for precise surface tuning and linkage safety.
