FLYSKY INr4-GYB 2.4GHz 4 Channel Receiver Instructions

FLYSKY INr4-GYB 2.4GHz 4 Channel Receiver

Introduction

The INr4-GYB receiver adopts Flysky’s third-generation automatic frequency hopping digital system (AFHDS 3). It uses a single-antenna bidirectional transmission system, with a built-in gyroscope and is uniquely designed to install and output PWM/PPM/i-bus/S.BUS/i-bus2 in signals. It supports an AFHDS3 transmitter.

Binding

1. Press and hold the receiver BIND button [5] while powering on the receiver,release the BIND button after the receiver is powered on powering on the receiver first, press and hold the BIND button 3 seconds, the LED [7] on the receiver will flash rapidly;

2. Put the transmitter into bind mode;

3. The binding process is complete when the LED on the receiver stops flashing and is on continuously.
   If a transmitter that has had its radio frequency (RF Standard) set to “AFHDS3 1 way” (please refer to your transmitter user manual) enters bind mode, the receiver LED will instead flash slowly. Exit bind mode on the transmitter and if the receiver LED stops flashing and is on continuously, the binding process is complete.

4. Check to make sure the transmitter and receiver functions are working correctly, repeat steps 1 to 3 (binding process) if any problem arises.

Forced update

If after a firmware update is performed and the transmitter is unable to bind t  the receiver, the receiver may need to be put into forced update times.

1. Power on the receiver while pressing the BIND button [5] for approximately ten seconds until the LED [7] flashes three times,Or power the receiver first, press and hold the BIND button for 10 seconds, and then th LED [7] flashes three times, release the BIND button.
2. Go to the RX Setup menu on your transmitter and select “RX Update”.
3. When the receiver LED flashes slowly, the update is successful.

Failsafe

The failsafe function is used to output the channel according to the out-of- control protection value set by the user afte the receiver loses its signal and is out of control to protect the model and personnel.

This receiver supports three failsafe modes: “Free”, “Hold”, and “Fixed value”; “Free” mode refers to PWM, PPM, i-Bus out, i-Bus 2 converter entering the failsafe state keep the channel value of no output signal. The S.BUS, i-Bus2, and i-bus converters output the last received signal channel value of the transmitter. “Hold” mode means that after entering the failsafe state, keep the output of the last transmitter signal;the “Fixed value” mode means that after entering the out-of-control protection state, the set signal channel value is maintained to output the signal

SVC Setting（NB4 interface）

The SVC function relies on the gyroscope to perform custom deviation correction on the direction of  the vehicle’s movement, helping the vehicle to have a better driving state.
The specific settings are as follows:

1. Function interface and default settings of smart vehicle control are shown in the right figure;

2. Click the / icon at the bottom of the interface to turn this function on or off;

3. Click “Neutral Calibration” to access the calibration animation interface;

   • “Neutral calibration” is used to calibrate the direction and throttle median with the gyroscope, enabling the vehicle to get into the best state when driving normally. Before turning on the smart
     vehicle control function, it is necessary to fine-tune the steering gear quantity and median of the vehicle and adjust the throttle median to the best driving state. After that, turn on the SVC to
     carry out median calibration. Every time the fine adjustment is changed, the median calibration will be carried out. During the median calibration, the handwheel and throttle should be set to
     their median positions and kept still before the calibration is completed；

4. Click “Reserve” to switch between “Normal/Reverse”.it can set the gyroscope mixing directio  channel；

5. Click “ESP Mode” to switch between “Normal/Lock”;

6. 1. Normal: When the vehicle yaws or turns, the gyroscope automatically provides an opposit compensation according to the angular velocity generated to control the steering gear to keep it
      stable or prevent drifting;

7. Lock: When the handwheel returns to and is kept at its median position, the gyroscope will control the steering gear in the opposite direction according to the yaw angle to make it return to the expected direction；

8. Click the “+/-” symbol settings displayed at the bottom of the “Steering Gain”, “Throttle Gain” and “Priority” interfaces, and the setting values range from 0% to 100%

9. Priority” is used to set the control ratio (turning radius) between handwheel control and gyroscope when the vehicle turns. When turning the vehicle with the handwheel, the steering
   angle will be reduced under the hybrid gyroscope control. When the value is 0%, the hybrid force is the largest, that is, the turning radius is the largest.
   When the value is 100%, the hybrid force is 0 and the turning radius is the smallest
   Gyroscope calibration is used to enable the gyroscope or change the gyroscope for the first time with the code. The model stays in a stable and static state, Click to calibrate and the receiver
   flashes 2 times and automatically exits, indicating that the calibration is successful.

Note: If you use a air transmitter such as PL18, it can only be used for basic purposes, and the SVC function cannot be realized.

Compatibility

The INr4-GYB receiver is compatible with all AFHDS 3 surface transmitters
(Note: It is currently applicable to NB4 2.0.93 and NB4 lite 1.0.10 and later versions. The high-frequency library used by the firmware is version 3.0.)

Attention:

• Make sure the product is installed and calibrated correctly, failure to do so may result in serious injury.
• Make sure the receiver’s battery is disconnected before turning off the transmitter, failure to do so may lead to unintende operation or loss of control.
• Make sure the receiver is mounted away from motors, electronic speed controllers or any device that emits excessive electrical noise.
• Keep the receiver’s antenna at least 1cm away from conductive materials such as carbon or metal.
• Do not power on the receiver during the setup process to prevent loss of control.
