설치 지침
Follow these steps to install the FMS 3-in-1 Mini Brushless System Combo Set and Pinion Gear into your compatible RC vehicle.

- 차량 준비: Ensure your RC vehicle (e.g., FCX24 K5 Black Brushless, FCX24 Power Wagon Brushless) is powered off and the battery is disconnected. Remove the existing motor and ESC/receiver unit if applicable.
- Install the Pinion Gear (C3684):

The C3684 Pinion Gear, designed for the 1212 3200KV brushless motor. Carefully attach the C3684 pinion gear to the shaft of the 1212 3200KV brushless motor (which is part of the C3891 combo). Ensure it is properly aligned with the vehicle's main gear and secured with the grub screw.
- Mount the C3891 Combo Unit:

Ensure it is protected from vibrations and potential impacts. The motor is integrated, so position the unit such that the motor can connect to the drivetrain.
- 전원에 연결: Connect your 2-3S LiPo battery to the power input of the C3891 ESC. Ensure correct polarity.
- Bind with Transmitter:
- 송신기를 켜세요.
- Power on the RC vehicle.
- Follow your transmitter's specific binding procedure. The C3891 unit (FS-RCABL-ESC-BS) will enter binding mode, indicated by a flashing LED.
- Once bound, the LED on the C3891 unit should become solid.
- 테스트 제어: Before full operation, test the steering and throttle responses to ensure they are functioning correctly and in the right direction. Adjust transmitter settings if necessary.
작동 지침
Once the system is installed and bound, you can begin operating your RC vehicle.
- 전원 켜기: Turn on your remote control transmitter first, then connect the battery to your RC vehicle.
- 운전: Use the throttle trigger/stick on your transmitter to control forward and reverse movement, and the steering wheel/stick for direction.
- 전원 끄기 : Always disconnect the battery from the RC vehicle first, then turn off your remote control transmitter. This prevents accidental runaway.
유지
- 청소: Regularly clean the motor and ESC/receiver unit to remove dirt, dust, and debris. Use a soft brush or compressed air. Avoid using liquids directly on electronic components.
- 검사: Periodically check all wiring and connections for signs of wear, damage, or looseness. Ensure the pinion gear is securely attached and free of excessive wear.
- 저장: When not in use, store the RC vehicle and its components in a dry, cool place away from direct sunlight. Disconnect the battery for long-term storage.
문제 해결
| 문제 | 가능한 원인 | 해결책 |
|---|---|---|
| No power to vehicle | Battery not connected, discharged battery, faulty wiring. | Check battery connection, charge battery, inspect wiring for damage. |
| 모터가 응답하지 않음 | Not bound to transmitter, motor wires loose, ESC error. | Re-bind transmitter, check motor connections, power cycle the ESC. |
| Erratic control/loss of signal | Interference, loose antenna, low transmitter battery. | Move to an area with less interference, check receiver antenna, replace transmitter batteries. |
| 모터 과열 | Incorrect gearing, excessive load, prolonged use. | Check pinion/spur gear ratio, reduce load, allow motor to cool down. |
