DYS Waterproof 50kg 14V Brushless Digital Servo (IP67)

A 50 kg·cm brushless digital servo for high-voltage systems. It runs on 10–14 V, so it can take a 3S LiPo (12.6 V fully charged) directly with no step-down BEC. Metal gears sit in a CNC-machined aluminium case sealed to IP67, making it a fit for heavy drone payload-release mechanisms, large fixed-wing control surfaces, robotic arms and RC crawler steering. Available in 180° and 270° travel versions.

Key features

• Stall torque of 37 kg·cm at 10 V rising to 50 kg·cm at 14 V
• 0.09 s per 60° at 14 V (0.12 s at 10 V)
• Brushless motor for less heat and longer life than brushed servo motors
• Accepts 50–333 Hz PWM frame rates, covering standard 50 Hz outputs and fast digital-servo refresh
• IP67 sealing against dust, mud and water

Keep it off 4S packs: 16.8 V fully charged is above its 14 V limit. A 5 V or 6 V receiver rail is below the 10 V minimum, so take power from the flight battery or a 12 V regulator and only the signal from the receiver or flight controller.
