Servo CS-40DS-BL, RC servo, standard size

The CS-40DS-BL brings brushless drive, 30 kg.cm actuating torque at 7.4 V and a 0.09 sec per 60° response into one RC servo built for precise control under load. Its black-blue housing, standard JR format and waterproof construction suit demanding running conditions where steering accuracy needs to stay sharp through mud, puddles and rain. Inside, the brushless motor works with a metal gearbox to convert control inputs into strong, direct servo movement. The 2 ball bearings support the output shaft for smoother operation when the linkage is under pressure. With dimensions of 40 x 20 x 29.95 mm and a weight of 66 g, the servo stays within a familiar standard-size format that fits many RC installations. The designation JR/MG/WP/0.11 also points clearly to its standard connection format, metal gear layout and waterproof build. The specification suits RC applications that call for strong steering force and quick correction, including heavier off-road models, crawlers and large trucks where the servo works hard through uneven terrain. In workshop upgrades as well as fresh builds, the CS-40DS-BL adds a focused combination of speed, torque and compact installation dimensions for 14 Years and up.
