- Accessing the Gimbal Bay: Carefully open the radio transmitter casing according to the specific service instructions for your X20/X20S model. This typically involves removing screws from the back of the case.
- Removing Existing Gimbal (if applicable): If replacing an existing gimbal, gently disconnect its wiring harness from the radio's main board. Unscrew and remove the old gimbal unit.
- Installing the MC11 Gimbal:
- Connect the MC11 gimbal's wiring harness to the corresponding port on the radio's main board. Ensure the connector is fully seated and oriented correctly.
- Position the MC11 gimbal in the designated bay within the radio casing. Align the mounting holes on the gimbal with those on the radio's chassis.
- Secure the gimbal using the provided mounting screws. Do not overtighten the screws.
- Reassembly: Carefully close the radio transmitter casing, ensuring all wires are clear of pinch points. Secure the casing with its original screws.
