DYS Waterproof 35kg 8.4V Brushless Digital Servo (IP67)

A 35kg-class brushless digital servo with metal gears, an aluminium case and IP67 sealing: the long-life choice for heavy crawler and truck steering, robotic joints, mechanical actuators and drone payload mechanisms. It runs on 6.0–8.4 V, straight from a 2S LiPo or an HV BEC.

Key features

• Brushless motor has no brushes to wear, so it outlasts coreless and brushed servos under continuous load
• 30 kg·cm at 6 V, 31 kg·cm at 7.4 V and 35 kg·cm at 8.4 V
• Fast transit: 0.09 s/60° at 6 V down to 0.06 s/60° at 8.4 V
• IP67 sealing for mud, rain and temporary immersion
• Available in 180° and 270° travel versions; 1 µs dead band for precise holding

Running current reaches 6.5 A at 8.4 V, so power it from a high-current BEC or directly from the pack; a receiver's onboard regulator is not enough.
