Setup and Installation
Before beginning installation, ensure your RC tank's power is off and the battery is disconnected. This unit is intended for installation within compatible Henglong 1/16 RC tanks.
Installation Steps:
- Prepare the Tank: Carefully open your RC tank's chassis according to its specific service manual to access the internal components.
- Locate Mounting Area: Identify the designated mounting area for the BB shooting unit, typically near the turret's barrel mechanism.
- Mount the Unit: Securely fasten the Henglong BB shooting unit into the tank's chassis using appropriate screws or clips (not included, typically part of the tank's original assembly). Ensure the unit is stable and does not obstruct other moving parts.
- Connect Wiring: Connect the unit's wiring harness to the corresponding port on your tank's main control board. Refer to your tank's wiring diagram for correct polarity and connection points. The unit typically requires power and a signal connection for firing.
- Barrel Alignment: Ensure the output nozzle of the BB shooting unit aligns correctly with the tank's barrel. Adjust as necessary to prevent BBs from getting stuck.
- Initial Test: Before reassembling the tank, connect the battery and perform a brief functional test to ensure the unit powers on and the firing mechanism responds to commands.
- Reassemble Tank: Once confirmed operational, carefully reassemble the RC tank's chassis.

Operating Instructions
Loading BBs:
- Ensure the tank's power is off before loading BBs.
- Locate the BB loading port on the top or side of the airsoft unit (or the tank's turret, if integrated).
- Carefully pour or insert the recommended 6mm plastic BBs into the loading port. Do not overfill.
- Close the loading port cover securely to prevent BBs from falling out during operation.
Firing Mechanism:
- Power on your RC tank and its remote control.
- Refer to your RC tank's remote control manual for the specific button or joystick command that activates the BB firing function.
- When the firing command is issued, the airsoft unit will propel a single BB out of the tank's barrel.
- Allow a brief moment between shots for the unit to cycle and load the next BB. Rapid firing may reduce performance or cause jams.
Maintenance
Regular maintenance ensures optimal performance and longevity of your BB shooting unit.
- Cleaning: Periodically inspect the BB loading port and barrel for any debris or stuck BBs. Use a soft brush or compressed air to clear obstructions. Ensure the unit is powered off before cleaning.
- Storage: When not in use, store the unit (and the tank) in a cool, dry place away from direct sunlight and extreme temperatures. Remove all BBs from the unit before long-term storage.
- Inspection: Regularly check wiring connections for looseness or damage. Ensure all mounting screws are tight.
