X20 Combo Brushless Servos - X20-2208 + X20-1035 Combo Set for RC Helicopter
KST X20 Combo Brushless Servo Set
The KST X20 Combo Set is a complete servo package for RC helicopters, including three X20-2208 V8.0 cyclic servos and one X20-1035 V3.0 tail servo.
Built for high-performance helicopter applications, the X20 series features brushless motors, full CNC aluminum cases, and hardened steel High Life Span (HLS) gears. Each gearbox uses 6 ball bearings to provide a smooth, precise, and virtually slop-free gear train.
The X20-2208 V8.0 cyclic servos deliver 2.5N.m of torque at 8.4V with a fast 0.07 sec/60° speed, while the X20-1035 V3.0 tail servo provides 1.2N.m of torque at 8.4V with an ultra-fast 0.03 sec/60° speed.
With a combination of high torque, rapid response, CNC construction, and durable HLS gearing, the X20 Combo Set provides a reliable and performance-focused servo solution for RC helicopter enthusiasts.
