What are the key mounting tips for this servo?

Secure the servo using firm mounting tabs and make sure the case has airflow. Use thread locker on metal-to-metal screws if your model experiences strong vibration.

Are metal gears included and how do they affect use?

Metal gearing provides improved durability under high torque, reducing wear when running heavy control loads compared with standard plastic gears.

Should I use a governor or limit travel settings?

Setting travel limits in your radio helps prevent overload and reduces the chance of gear damage. Use endpoint adjustment to match your surface geometry and avoid overworking the servo.
