SG90 9g Micro Servo for Small Aircraft Models
THE BENEFITS OF CHOOSING US
Description
The SG90 9g Micro Servo for Small Aircraft Models delivers 1.6kg·cm @4.8V with a 0.1s/60° @4.8V transit time, running on 4.8V.
It is built with a Nylon train, not waterproof construction, 9g weight.
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: 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.
