Environmentally Friendly Disposal

The FS-MG4 is a digital proportional radio control system designed for use with remote-controlled cars and boats. It is a 4-channel transmitter that utilizes the latest AFHDS 2.4GHz ATN frequency hopping technology from Flysky, ensuring reliable and stable communication between the transmitter and receiver. The system is designed to be lightweight, compact, and ergonomic, making it comfortable for users, especially beginners.

Function Description

The FS-MG4 transmitter controls up to four channels:

CH1: Steering Wheel: This channel is controlled by the traversing handwheel, which can be turned 35 degrees on each side.
CH2: Throttle Trigger: This channel is controlled by the throttle button, offering 25 degrees of movement forward and 12.5 degrees backward.
CH3: Three-position Toggle Switch: This switch provides three distinct positions for controlling a third channel.
CH4: Reset Button: This push-button switch functions as a flip type, toggling its output between 1000us and 2000us with each press.

The system includes several functions to enhance control and user experience:

Channel Reverse: The ST.REV and TH.REV knobs allow users to adjust the action direction of the servo or motor for CH1 and CH2, respectively. An "up" position indicates reverse, while a "down" position indicates normal operation.
Trims (ST.TRIM / TH.TRIM): These functions are used to fine-tune the neutral position of the steering (CH1) and throttle (CH2). The ST.TRIM can also be multiplexed for CH3, and TH.TRIM for CH4, depending on the mode. Adjustments can be made counterclockwise to increase the trim value (up to +120us) or clockwise to decrease it (down to -120us).
Dual Rate (D/R) (ST.D/R / TH.D/R): This feature allows users to adjust the maximum servo travel for steering (CH1) and throttle (CH2). Similar to trims, ST.D/R can be multiplexed for CH3, and TH.D/R for CH4. Counterclockwise adjustment increases the servo amount (up to 120%), while clockwise adjustment decreases it (down to 0%).
Mode Switching: The transmitter supports two modes, allowing the ST.TRIM, ST.D/R, TH.TRIM, and TH.D/R buttons to be reused for different channels. By default, Mode 1 is active, where these controls are assigned to CH1 and CH2. In Mode 2, they are assigned to CH3 and CH4. Users can switch between modes by pressing the BIND button twice within one second.
Failsafe: This critical safety function allows users to pre-set the receiver's behavior in case of signal loss from the transmitter. Once configured, the receiver will output the set failsafe values, ensuring the model reacts predictably and safely.
Beginner Mode: Designed for new users, this mode limits the throttle to 50% and sets the channel range to 1250~1500~1750us, making the model easier to control. The system defaults to normal mode, but can be switched to beginner mode by holding the channel 4 button, turning the handwheel counterclockwise to the bottom, and then powering on the transmitter.

Usage Features

The FS-MG4 is designed for ease of use, particularly for beginners:

Battery Installation: The transmitter requires 4 AAA batteries. Users must ensure proper polarity during installation. A low battery alarm (G.LED flashing slowly) indicates when the battery voltage drops below 4.2V.
Power On/Off: To power on, users check battery charge, toggle the power switch to [ON], and then connect the receiver to power. The R.LED will illuminate when active. For safety, the transmitter should always be powered on before the receiver. To power off, disconnect the receiver power first, then toggle the transmitter's power switch to [OFF].
Binding: The transmitter and receiver are pre-bound at the factory. However, if a new receiver is used or re-binding is necessary, users can enter bind mode by holding the BIND button while turning on the transmitter (G.LED flashes quickly). The receiver will automatically enter bind mode when powered on. Successful binding is indicated by the receiver's LED flashing slowly and the transmitter's LED remaining solid after reboot.
Stick Calibration: This function allows users to set the neutral position for the throttle and wheel. While calibrated at the factory, recalibration can be performed by holding the wheel clockwise and throttle forward, then powering on the transmitter in calibration mode. The R.LED and G.LED will flash twice. Users then turn the wheel fully clockwise and counterclockwise (R.LED turns off), then pull the trigger fully back and forward (G.LED turns off). Finally, pressing the BIND key saves and exits the calibration.

Maintenance Features

While the manual does not explicitly detail maintenance features, it provides important safety guidelines that contribute to the longevity and safe operation of the device:

Battery Care: Users are instructed to only use specified batteries, avoid opening, disassembling, crushing, puncturing, or exposing batteries to excessive heat or liquids. Batteries should not be dropped or exposed to strong shocks/vibrations and must always be stored in a cool, dry place. Damaged batteries should not be used.
Environmental Precautions: The product should not be used at night, in bad weather (rain, thunderstorms, snow), or when visibility is limited, as moisture or erratic operation can lead to loss of control.
Interference Avoidance: To prevent loss of control due to interference, users should avoid operating near other radio control activities, power lines, communication antennas, people, roads, or on bodies of water with passenger boats.
Physical Safety: Users are warned not to touch hot parts of the model during or after operation to prevent burns.
Antenna Mounting: For optimal signal quality, the receiver antenna should be mounted perpendicular to the model body in an upright position.
Product Updates: Users are encouraged to visit the Flysky website for updated product information and manuals, ensuring they have the latest guidance for their device.
