THE BENEFITS OF CHOOSING US
Description
The HB35KG 35KG Brushless Waterproof Digital Servo for Boats & Cars delivers 35kg·cm, running on 6.0-8.4V.
It is built with a Metal Gear train, Aluminum Housing case, 3BB, ip67 construction, 75g weight, 40x20x37mm body, JR JST 300mm connector as standard.
A brushless motor removes the brushes entirely, which means less internal wear and more consistent torque over a long service life.
This is a high-voltage servo: it reaches full rated torque on 2S LiPo or a 7.4–8.4V BEC, and it will still run on 6.0V with reduced torque. Check the BEC rating of your ESC before you connect it.
Operating angle is available in 180°/270°/360° Optional, so the same body can be ordered for standard control-surface work or for winch and robot-joint applications that need more than 180°.
At this torque level you are into 1:8 and 1:6 crawlers, rock racers, large-scale models and heavier UAV control surfaces, where the linkage can stall a weaker servo.
