The KST DS135MG is the compact companion to the DS125MG — sharing the same 10mm ultra-slim profile and zero-backlash hardened steel gear train, in a shorter 29.6mm body optimized for tighter wing bay installations. Delivering 5.2 kgf.cm at 6.0V with a crisp 0.12s/60° response, it brings industry-benchmark precision and 90% of top-tier performance to F3F, F3B, F3J, and F5J pilots at less than half the cost of leading premium servos.

Key Features

  • Ultra-Slim 10mm Profile: Identical width to leading premium wing servos, with a shorter 29.6mm body that fits compact and narrow glider wing bays where the DS125MG may not.
  • Zero Backlash Geartrain: Hardened steel gears with precision fit deliver play-free, repeatable surface control for exact aileron and flap positioning.
  • Coreless DC Motor: Fast linear response, smooth travel, and consistent centering across the full range of motion.
  • Dual Ball Bearings: Dual-bearing output shaft support reduces friction and enhances centering accuracy under sustained aerodynamic hinge loads.
  • Full CNC Aluminum Casing: Precision-machined alloy housing ensures accurate wing bay fitment, structural integrity, and effective heat dissipation.
  • Programmable & Soft Start: Configurable travel limits with soft-start protection for precise surface tuning and linkage safety on power-up.
