This product only includes the remote control + receiver board (main board). Customers need to prepare batteries, motors, and hulls by themselves—we do not sell batteries, motors, or hulls in this store.

Specification:

- Receiver board compatible batteries: 7.4V lithium battery pack, 7.2V lithium battery pack. Maximum withstand voltage: 14V

(Do NOT use dry batteries—dry batteries have poor current output capability, which will prevent the motor from starting.)

- Receiver board compatible motors: the maximum output current of each path of the receiving board motor driver is about 5A, which can drive small and medium-sized motors with load currents within 4A; the motor's stall current is recommended to be within 5A.

- Connection for receiver board: refer to the picture shown

- Receiver board interface A: defaults to connecting to an LED light (current-limiting resistor: 270 ohms).

- Receiver board interface B: defaults to connecting to a 130 fishing bait motor (current-limiting resistor: 10 ohms).

- Battery for remote controller: 4pcs AA battery (NOT included)

- Remote control channels (4 channels total):

1. Forward/backward control of the left motor

2. Forward/backward control of the right motor

3. LED light control channel

4. Fishing bait motor control channel

(Speed is not adjustable)

- Remote control distance: 500 meters

- Remote control power consumption: 25mA

- Weight for remote controller: about 172g

- Weight for receiver board: about 14g

Recommended configuration:

- Battery: 7.4V rechargeable battery

- Motor: 390 motor

(Do NOT use high-power motors (e.g., 380, 550 motors)—excessive load current may damage the control board.

Note: Motor types and manufacturers vary; even motors of the same type may have different drive currents. Factors like supply voltage, battery protection board, motor load, and motor stall current will affect the final current. For safety, please measure the motor parameters before use to avoid damaging the control board due to motor mismatch.)

- If the load current of your motor exceeds 5A under 7.4V voltage, please replace it with a lower-power motor, or use a battery with lower voltage (e.g., 3.7V, 4.8V, 6V batteries).

Features:

- Automatic code matching at power-on, no string coding, one-to-one remote control.

- The remote control distance is 500 meters.

- High power, each motor drive can output a maximum of 5A current.

- The left and right handles control the left and right motors respectively, and there are motor power fine adjustment buttons.

- There are nesting motor control and LED control buttons.

- Applicable to: RC bait boats, remote control tanks, differential speed cars, differential speed boats

Operating Instructions:

1. Insert 4 AA batteries into the remote control, turn on the switch to power it on, and the indicator light will flash.

2. Insert the battery into the receiver board, turn on the switch to power it on, and it will automatically pair with the remote control. Once pairing is successful, the indicator light will change from flashing to steady on. You can turn on the remote control first or the receiver board first—automatic pairing will work either way. (Keep the receiver board and remote control more than 20cm apart during use)

3. Control functions:

- The left joystick controls the forward/backward direction of the left motor; the right joystick controls the forward/backward direction of the right motor.

- The two buttons on the side of the direction joysticks are the fine-tuning buttons for increasing or decreasing the motor speed.

Important Notes Before Purchase:

1. Suitable for RC bait boats with motors mounted on the left/right sides, or toys that turn via differential speed.

(NOT suitable for toys that turn via servos or steering motors!)

2. All receiver boards have passed factory inspection. However, since customers need to adapt batteries/motors independently. We do NOT accept returns, exchanges, or after-sales service for the receiver board due to unstable personal DIY operations! We do NOT accept returns, exchanges, or after-sales service for the receiver board! Thank you!

3. The receiver board can only pair with the remote control from our store (incompatible with remotes from other manufacturers). The remote control can only pair with our store's products (incompatible with model toys from other manufacturers).

4. The wireless transmission signal is strong. When in use, keep the remote control and control board more than 20cm apart—if the distance is too close, the wireless signal will saturate, causing connection failure between the remote control and control board.

Note:

- The battery, RC bait boat, motor and others in picture showed will not include.

- It is suitable for toys that make motors on the left and right sides, or DIY differential toys. can not be used for servo or steering motor.

Package include:

1pcs x Remote controller

1pcs x Receiver

Frequently Asked Questions (FAQs)

1. The remote control light does not turn on after inserting batteries.

- Answer: The battery is inserted with reversed positive and negative poles; or the battery is dead.

2. The indicator light of the receiver board does not turn on after inserting batteries.

- Answer: The switch is not turned on; the battery is dead; the positive and negative wire sequence of the battery interface and the receiver interface is reversed.

3. The receiver board and remote control cannot pair, and the indicator light keeps flashing.

- Answer: The distance between the remote control and the receiver board is too close, causing wireless signal saturation.

4. When pushing any handle, the indicator light of the receiver board flashes off briefly, and the motor fails to run or can only drive one motor.

- Answer: The receiver board battery is dead, or the battery cannot output a large current to drive the motor. Please do not use dry batteries or expired batteries.
