Steering Gear Control:

The control of the steering gear generally requires a time base pulse of about 20ms, and the high level part of the pulse is generally the angle control pulse part in the range of 0.5ms~2.5ms.

Servo 0-180 Degree
The corresponding control relationship is as follows:
0.5ms—————0 degrees;
1.0ms————–45 degrees;
1.5ms————–90 degrees
2.0ms————–135 degrees;
2.5ms————–180 degrees

Note:
1. Servo Plastic means spindle and gearwheel are Plastic made.
2. This servo is suitable for ordinary small electric aircraft models and is not recommended in large fixed wing and electric helicopter.
3. For 180 degree servo, some controllers can not control the angle accurately; please use a professional PWM Servo Controller to control the angle, as shown in the video:  https://youtu.be/zv6vd7eud_o
