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

A 35kg-class coreless digital servo with metal gears, an aluminium case and IP67 sealing, for heavy RC crawler and truck steering, robotic joints, actuators and drone mechanisms in wet or muddy conditions. It is rated for 6.0–8.4 V, so a 2S LiPo or an HV BEC drives it directly.

Key features

• Coreless motor's low rotor inertia gives quick acceleration and precise positioning
• 30 kg·cm at 6 V and 32 kg·cm at 7.4 V
• 0.09 s/60° at 6 V and 0.075 s/60° at 7.4 V
• IP67 sealing against dust, mud and temporary immersion
• Available in 180° and 270° travel versions; 1 µs dead band

Coreless or brushless? The brushless 35kg IP67 servo in the same range suits continuous-duty work; this coreless version draws less current (3.5 A against 5.5 A at 7.4 V) for similar torque, which eases the load on your BEC.
