About the INJS11B 11kg Waterproof Metal Gear Digital Micro Servo


Powerful Micro Performance

The INJS11B 11kg digital micro servo delivers high-torque, fast-response control for steering, shifting, and dig functions. Its coreless motor provides smooth, efficient operation in a compact package ideal for the Redcat Ascent-18. With up to 11 kg-cm of torque at 8.4V and a speed of 0.074 sec/60°, it provides strong, precise inputs for navigating technical terrain. Its compact size makes it an excellent upgrade where space is limited.

Rugged Waterproof Construction

An O-ring sealed waterproof design and stainless steel gears provide reliable performance in demanding conditions. High-voltage compatibility supports 6–8.4V operation, with 8 kg-cm of torque at 6V, 9.5 kg-cm at 7.4V, and up to 11 kg-cm at 8.4V. The stainless steel gear train is built for durability and repeated use, while the CNC-machined aluminum case adds strength and a premium finish.

Weighted Brass Mount

The CNC-machined brass servo mount eliminates flex while adding 12.3g of unsprung weight. This strategic weight lowers the center of gravity, improving stability, steering precision, and crawling performance. The rigid brass construction helps maintain consistent steering geometry under load. Its sleek finish also adds a clean, upgraded look to the chassis.
