MG90S 14g Micro Servo for Robot Arm & RC Models
THE BENEFITS OF CHOOSING US
Description
The MG90S 14g Micro Servo for Robot Arm & RC Models delivers 1.8kg·cm @4.8V / 2.2kg·cm @6.0V with a 0.10s/60° @4.8V / 0.08s/60° @6.0V transit time, running on 4.8V – 6V.
It is built with a Plastic train, not waterproof construction, 13.4g weight, 22.8×12.2×28.5mm 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 4.8V – 6V: 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°, 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 torque class suits 1:16–1:18 cars, small fixed-wing models, micro robot arms and camera gimbals, where weight matters more than holding force.
Ordering for a build or a distribution line? Tell us the torque, voltage range and connector you need and we will quote it. See also the full Yadovex range and our guides on choosing 6S long-range motors and 7-inch vs 9-inch propulsion.
