ANNIMOS DS3245SG 45kg High Torque Servo – 8.4V Coreless, IP67 Waterproof, 270° for 1/8–1/12 RC Cars

Powerful, Precise, and Ready for Tough RC Builds

The ANNIMOS DS3245SG 45kg servo is engineered for demanding RC projects and DIY robotics. A coreless motor paired with stainless steel gears delivers reliable torque and smooth motion, even under load. With IP67 waterproofing, it stands up to dust, moisture, and rough terrains, making it a versatile choice for off-road rigs, crawlers, and robotic joints.

Key Capabilities

• Heavy‑duty torque: up to 51 kg·cm at 8.4V, enabling solid steering and robust actuation.
• Fast response: no‑load speed as quick as 0.11 sec/60° at 8.4V for snappy control.
• Broad voltage range: designed for 5–8.4V operation, with precision PWM control (500–2500 μs).
• High build quality: stainless steel gears, double bearings, waterproof seals, and CNC aluminum shell for stability and longevity.
• Wide compatibility: suitable for 1/8, 1/10, and 1/12 scale RC cars, trucks, and robotic applications.

Real‑World Use Scenarios

In a rugged RC car, the DS3245SG can drive heavy front suspensions or accessory arms without slowing down. For a crawler or robot project, the 270° rotation range and precise positioning support complex joints and repeatable motions. The waterproofing helps maintain performance in wet or dusty tracks, while the compact footprint fits tight spaces in custom builds.
