8-Channel Servo Tester & 25kg Digital Servo

This bundle pairs an eight-channel servo tester with a high-torque digital servo for RC builders and hobbyists. The tester centres and drives up to eight servos simultaneously while the included DS3218MG delivers strong holding force for demanding control surfaces or robotic joints.

Over-current protection with dual control modes

The tester features built-in over-current protection to safeguard connected servos and power sources during bench sessions. Two selectable control modes let you switch between manual knob adjustment and automatic sweep cycling, simplifying setup and calibration workflows at the workbench.

Full metal gear servo with 180° travel

The DS3218MG uses full metal gears rated for 25kg torque and a 180° control angle, replacing weaker plastic-gear servos in large-scale planes, helicopters or ground vehicles. The upgrade is worth it when your model demands precise, durable actuation under heavy loads.
