ZOSKAY 25KG Digital Servo - Metal Gear, CNC Aluminium, IP67 Waterproof for 1/8 1/10 RC Cars

The ZOSKAY 25KG Digital Servo delivers up to 25 kg·cm of torque at 6.8V with a speed of 0.13 sec/60°, designed for 1/8 and 1/10 scale RC cars that require reliable steering or throttle response. Its metal gear train and CNC aluminium middle shell enhance durability and heat dissipation, while the IP67 waterproof rating makes it suitable for wet terrain.

Torque and Speed Performance

At 6.8V, this servo provides a maximum torque of 25 kg·cm (347 oz·in) and a transit speed of 0.13 seconds per 60 degrees. This combination offers strong holding power and quick response for demanding RC applications. The high-voltage (HV) design allows efficient power use from 2S LiPo batteries.

Metal Gears and CNC Aluminium Shell

The servo features hardened metal gears with a copper and aluminum construction, treated with hard anodizing for better accuracy and wear resistance. The CNC-machined aluminium middle shell acts as a heat sink, improving heat dissipation during sustained use. This helps maintain performance and prolongs the servo's lifespan.

IP67 Waterproof Design

With an IP67 rating, the servo is protected against dust ingress and can be submerged in up to 1 meter of water for 30 minutes. This makes it a practical choice for RC cars that encounter mud, puddles, or wet grass. Note that the IP67 rating applies to the servo body; connectors and wiring should still be secured.

Dimensions and Compatibility

The servo measures 40 x 20 x 40.5 mm (1.58 x 0.79 x 1.60 in), fitting standard servo mounts found on most 1/8 and 1/10 scale RC vehicles. It features a 180° control angle, suitable for steering linkages or throttle arms. Ensure your receiver and battery can supply 6.8V for full torque.

Common Questions About the ZOSKAY Servo

What voltage should I use?

For the specified 25 kg·cm torque, use 6.8V. The servo is HV-compatible, but the exact operating range is not provided. Check your system's voltage capability.

Is it truly waterproof?

Yes, the IP67 rating means it's dust-tight and can handle temporary submersion. However, connectors and wiring are not covered; waterproof connectors are recommended for full protection.

Will it fit my RC car?

The servo is standard size (40x20x40.5 mm) and fits most 1/8 and 1/10 scale vehicles with standard servo mounts. Verify your model's servo compartment dimensions.

What materials are the gears made of?

The gears are metal, specifically copper and aluminum alloys with hard anodizing for strength and precision. This reduces backlash and improves durability over plastic gears.
