MG30KG 30KG 180° High Torque Full Steel Gear Digital Servo for RC Crawler
THE BENEFITS OF CHOOSING US
Description
The MG30KG 30KG 180° High Torque Full Steel Gear Digital Servo for RC Crawler delivers 30.0kg·cm, running on DC 5-8.4V.
It is built with a Full Steel Gear (All Metal) train, Half Aluminum Alloy case, Top & Bottom Bearings, not waterproof construction, 68g weight, 40x20x46mm body.
A conventional brushed DC motor keeps the cost down and the torque curve predictable, which suits general-purpose RC and robotics use.
Rated for DC 5-8.4V: 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° customizable), 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.
