Product Introduction

About the Model

The FCX24 Power Wagon is the first product in the FCX24 series. It features a refreshed paint job, a rear cargo box design, new rims, and Batrazzi mud tires. It is equipped with FMS's brushless power system.

The chassis is based on the FCX24 platform and includes a micro two-speed mechanical transmission. It features a new 1212 outrunner brushless motor for increased torque and smooth, precise linear control. The outer-rotor design minimizes noise and vibration while enhancing high-speed performance and crawling. Portal axles with metal gears increase ground clearance and off-road capability, especially over obstacles at low speeds. Metal steering linkages and available upgrade parts (metal link rods, differentials, universal joint drive shafts, metal gears, brass wheel counterweights) enhance durability and customization.

Getting Started

Transmitter Battery Installation

Danger: Only use specified battery (4x AAA batteries). Do not open, disassemble, short, crush, puncture, expose to heat/liquids, drop, or use damaged batteries. Store in a cool, dry place.

Follow these steps:

1. Open the battery compartment cover.
2. Insert 4 AAA batteries with correct polarity.
3. Replace the battery compartment cover.

Low battery alarm: Transmitter LED flashes slowly when battery is below 4.2V.

Diagrams show correct battery polarity and the location of the battery compartment.

Receiver and Servo Installation

Install the receiver in an appropriate location to ensure a stable signal and maximum range. Avoid placing it near motors or sources of electrical noise. Keep the receiver's antenna away from conductive materials (metal, carbon fiber) by at least 1cm.

Caution: Do not power on the receiver during installation to prevent damage.

Operation Guide

Power On Sequence

For safety, always power on the transmitter before the receiver.

1. Ensure the transmitter battery is fully charged and installed correctly.
2. Toggle the transmitter's power switch to [ON]. The R.LED will light up.
3. Connect power to the receiver.

Operate with caution to avoid damage or injury. Ensure the throttle trigger is at neutral and switches are in their proper positions before powering on.

Diagrams illustrate LED status indicators on the transmitter.

Instructions

LED Indicators

• R.LED: Red power indicator.
• G.LED: Green status indicator.
• RX.BATT: ESC battery power indicator (Green: High, Orange: Medium, Red: Low, Flashing Red: Ultra Low).

Binding

The transmitter and receiver are pre-bound from the factory. If replacement or additional receivers are needed:

1. Turn on the transmitter while holding the BIND button to enter bind mode (G.LED flashes quickly).
2. Power on the receiver. It will wait for connection and automatically enter matching code mode if no connection is made within 1 second.
3. Binding is successful when the receiver LED and transmitter G.LED are solid.

Note: Put the transmitter into bind mode first, then the receiver. If binding fails within 10 seconds, the receiver LED will flash slowly.

Diagrams show the BIND button and LED indicators during the binding process.

Stick Calibration

This function calibrates the neutral position for the steering wheel and throttle trigger. Recalibration steps:

1. Turn the wheel fully clockwise, hold the throttle fully forward, then turn on the transmitter in calibration mode. (R.LED & G.LED flash twice, RX.BATT solid yellow).
2. Calibrate steering: Turn the wheel to max and min travel points. (R.LED off, RX.BATT solid red).
3. Calibrate throttle: Push/pull the throttle trigger to max forward/backward. (G.LED off, RX.BATT solid green).
4. Calibration complete. (RX.BATT off).
5. Press the BIND button to save and exit.

Diagrams illustrate the LED status during calibration.

Power Off Sequence

Follow these steps to turn off the system:

1. Disconnect the receiver power.
2. Toggle the transmitter's power switch to the off position.

Danger: Always disconnect receiver power before turning off the transmitter to prevent damage or serious injury.

Receiver Binding

This receiver supports two-way binding and automatically enters binding mode upon power-on.

• The receiver waits for connection to the bound transmitter.
• If no connection is made within 2 seconds, it enters binding state for 10 seconds.
• Successful binding results in normal communication status.

Binding Steps:

1. Put the transmitter into binding mode.
2. Turn on the receiver; it will wait for connection and automatically enter binding mode if no connection is made (receiver LED flashes fast).
3. Receiver LED is solid on after successful binding.
4. Verify transmitter and receiver operation. Repeat steps to re-bind.

Note: Set the transmitter to binding state first, then the receiver. If binding is not completed within 10 seconds, the receiver LED flashes slowly.

Diagrams show receiver LED status during binding (fast flash: binding, slow flash: waiting, solid: connected).

Receiver Protection & Features

• Low Voltage Protection: CH2 output stops, LED flashes slowly.
• High Voltage Protection: All channels stop output, LED flashes fast.
• Overheating Protection (ESC): CH2 output stops, LED flashes fast. Resumes when temperature is normal.
• Battery Voltage Feedback: Receiver returns battery voltage status (high, medium, low, ultra-low) to the transmitter.

LED Light Control

When the transmitter is in normal communication, press the transmitter's BIND button to turn the LED light on or off. By default, the LED light is off. It turns on for one second upon receiver power-on before turning off.

ESC & Motor Instruction

The receiver ESC supports drag brake settings (0%, 50%, 75%, 100%) and running modes (forward/reverse or forward/reverse/brake) configurable via the transmitter.

After motor connection:

• The connected battery type is indicated by motor beeps (e.g., 2 fast beeps for 2S LiPo, 3 fast beeps for 3S LiPo).
• Throttle neutral calibration is confirmed by a long beep once. If not recognized, the motor beeps quickly. No power output occurs until calibration is successful.

Default settings: Drag brake force 0%, running mode forward/reverse/brake.

Failsafe

The fail-safe function activates when radio signal is lost between transmitter and receiver.

• Default: CH2 (ESC) enters brake status. CH1 and CH3 maintain last output.
• User-configurable fail-safe values for CH1 and CH3 can be set on the transmitter.
• The LED light status remains unchanged during out-of-control.

Attention: Ensure correct installation and calibration. Unreasonable fail-safe settings may cause accidents. Keep receiver away from electrical noise. Do not power on receiver during setup. Re-power receiver after throttle trim changes.

Vehicle Setup

Charging the Battery

Car Battery: 2S LiPo 7.4V 380mAh (Note: The PDF lists 938000mAh, which is likely a typo; 380mAh is used here for consistency with the spare parts list). Charger: USB balance charger, charging time 30-45 minutes.

Charging Steps:

1. Connect the USB port of the balance charger to a power source.
2. Connect the battery to the balance charger to start charging.
3. Charging LED is red; charging complete LED is green.

Do not charge unattended! If battery or charger overheats, disconnect immediately due to potential internal short circuit.
