JX CLS6327HV 27kg Coreless Metal Gear Digital Servo

The JX CLS6327HV is a high-voltage digital servo with a coreless motor, metal gear train and CNC aluminium case. Delivering up to 27.45 kg·cm of stall torque and 0.09 s/60° at 7.4 V, it suits large fixed-wing control surfaces, payload-release and drop mechanisms, and other drone actuation jobs that need strong, fast movement.

Key features

• Coreless motor for quick acceleration and smooth, precise movement
• Metal gears and dual ball bearings to carry sustained load
• CNC aluminium shell for a rigid, durable case
• 1 µs dead band with 1520 µs centre and 330 Hz signal support for precise holding
• JR connector on a 250 mm lead, with a set of servo fittings included

The servo is rated for 6.0–7.4 V, so run it from a regulated BEC set within that range rather than straight off a 2S LiPo, which reaches 8.4 V fully charged. Size the BEC for peak current when several high-torque servos move at once.
