The KST X20 Combo Brushless Servos set combines three X20-2208 V8.0 cyclic servos with one X20-1035 V3.0 tail servo for RC helicopter builds. KST positions the combo for 500-800 class EP/GP helicopters that need a matched cyclic and tail servo package. Verified KST data lists the X20-2208 cyclic servo at up to 2.5N.m torque at 8.4V and 0.07sec/60deg speed at 8.4V. The included X20-1035 V3.0 tail servo is listed at up to 1.2N.m torque at 8.4V and 0.030sec/60deg speed at 8.4V. Both servo models use brushless DC motors, hardened steel HLS gears, aluminum alloy cases, and 25T 6mm output splines. The combo is a convenient single-package option for helicopter cyclic-plus-tail servo upgrades.
