2. Langkah-langkah Keselamatan
Always observe the following safety guidelines to prevent injury or damage to the product and surrounding equipment:
- Keselamatan Bateri: Use only compatible LiPo batteries (2-6S). Incorrect battery voltage can cause severe damage. Always handle LiPo batteries with care, as they can be volatile if mishandled.
- Pendawaian: Ensure all connections are secure and correctly polarized. Incorrect wiring can lead to short circuits and component failure.
- Penebat: Please ensure all solder joints are insulated with heat shrink where necessary to prevent short circuits.
- Sambungan Motor: Connect the ESC to the motor before connecting to the battery.
- Penentukuran Pendikit: Always perform throttle range calibration before the first flight or if changing transmitters.
- Permulaan permulaan: The motor will not start immediately, regardless of the throttle lever position, ensuring safety during power-up.
- Terlalu panas: Avoid continuous high-load operation without adequate cooling, as this can lead to overheating and damage.
- Pendedahan Air: This ESC is not waterproof unless explicitly stated. Avoid exposure to moisture.

5.2 Normal Start-up Procedure
- Turn on the transmitter. Move the throttle stick to the bottom (minimum) position.
- Connect the ESC to the battery. Wait for 2 seconds. The motor will emit a "BEEP" sound, indicating the number of LiPo cells detected.
- Wait for 1 second. The motor will emit a continuous long and 1 short "BEEP" sound, indicating that the brake is available. If it emits a long tone, the ESC is ready for operation.
5.3 Penentukuran Julat Pendikit
This procedure ensures your ESC recognizes the full throttle range of your transmitter.
- Turn on the transmitter. Move the throttle stick to the top (maximum) position.
- Connect the ESC to the battery. Wait for 2 seconds. The motor will emit a "BEEP-BEEP" sound, indicating that the full throttle position is memorized.
- Move the throttle stick to the bottom (minimum) position. Wait for 1 second. The motor will emit a "BEEP" sound, indicating that the low throttle position is memorized. The motor will then emit a "BEEP" sound, indicating the number of LiPo cells. If it emits a long tone, the ESC is ready for operation.
6. Arahan Operasi
The ApisQueen 120A ESC allows for parameter programming directly via your remote control, eliminating the need for a separate programming card.
6.1 Mod Pengaturcaraan
Untuk memasuki mod pengaturcaraan:
- Turn on the transmitter. Move the throttle stick to the top (maximum) position.
- Connect the ESC to the battery. Wait for 2 seconds. The motor will emit a "BEEP-BEEP" sound.
- Continue to wait for 5 seconds. The motor will emit a special tone "12321", indicating that it has entered programming mode.
Once in programming mode, you can use the throttle stick to navigate and select programming options. Refer to the detailed programming sequence provided with your product for specific parameter adjustments.
7. Penyelenggaraan
To ensure the longevity and optimal performance of your ApisQueen 120A ESC, follow these maintenance guidelines:
- Pemeriksaan Berkala: Periodically check all wires and connectors for signs of wear, fraying, or corrosion. Ensure all solder joints are solid.
- Pembersihan: Keep the ESC clean and free from dust, dirt, and debris. Use a soft, dry brush or compressed air for cleaning. Avoid using liquids.
- Storan: Simpan ESC di tempat yang sejuk dan kering, jauh daripada cahaya matahari langsung dan suhu yang melampau.
- Pengurusan Haba: Ensure adequate airflow around the ESC during operation to prevent overheating. Do not cover the ESC with insulating materials.
- Kemas kini Firmware: Semak pengeluar website for any available firmware updates, though this model is designed for parameter setting via remote control.
