DYS Waterproof 70kg 14V Brushless Digital Servo (IP67)

A 70 kg·cm brushless digital servo with reinforced steel gears and pins inside a full aluminium housing sealed to IP67. It runs on 10–14 V, so a 3S LiPo (12.6 V fully charged) can power it directly. Use it where loads are heaviest: large payload-release and drop mechanisms, big fixed-wing control surfaces, robotic arms and heavy RC crawlers. Available in 180° and 270° travel versions.

Key features

• Stall torque of 56 kg·cm at 10 V, 65 kg·cm at 12 V and 70 kg·cm at 14 V
• 0.09 s per 60° at 14 V, 0.13 s at 10 V
• Reinforced steel gears with pins, running on two ball bearings
• Brushless motor for less heat and longer life than brushed servo motors
• PWM control with a 500–2500 µs pulse width and 50–333 Hz frame rate

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.
