THE BENEFITS OF CHOOSING US
Description
The HB8070GS 70KG High Voltage Brushless Waterproof Digital Servo delivers 70kg·cm with a High Speed transit time, running on 10V~15V.
It is built with a Metal Gear train, Aluminum Alloy case, dual ball bearings (2BB), waterproof construction, 89g weight, 40x20x40.5mm 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.
Rated for 10V~15V: confirm that your BEC or receiver pack can supply the stall current of this servo before you install it, especially if you are driving several servos from one source.
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°.
This is a heavy-duty industrial class servo – large-scale RC, agricultural machinery and robot joints where stall torque, not speed, is the limiting factor.
