Interface Introduction
CH1~CH7: To output PWM signal (Additional, CH1 can output PPM signal). Can be connected to the servos, or other compatible components. BVD/VCC: During the battery voltage detecting process, a BVD harness is connected here. During normal operation, the power cable is applied to this interface. BIND interface: During the binding process, a binding cable is connected to this interface. SENS interface: For connecting i-BUS sensors. SERVO interface: To output i-BUS or S.BUS signal, and support channel expansion in i-BUS type.
Binding
The receiver supports two -way binding and one-way binding. The transmitter will display the information returned from the receiver after the two-way binding is completed.
Follow the steps below to bind in two-way binding:
-
Select [ANT 2 WAY] for RF standard of the transmitter, then put the transmitter in bind mode.
-
The receiver supports three ways to enter bind mode: BIND button binding, bind cable binding and BIND button binding after power-on.
• BIND button binding: Press and hold the BIND button of the receiver while powering on the receiver, the LED of the receiver should be flashing, indicating that the receiver is in bind mode. Then release the BIND button.
• Bind cable binding: Insert the bind cable to the BIND interface of the receiver, then power on the receiver. The LED of the receiver should be flashing, indicating that the receiver is in bind mode. Note that you need to remove the bind cable from the receiver after the binding process is completed.
• BIND button binding after power-on: The receiver has not been connected to the transmitter when it is powered on. Press and hold the BIND button for 3 seconds, the LED of the receiver should be flashing, indicating that the receiver is in bind mode. Then release the BIND button. -
When the LED of the receiver is solid on, the binding process should be completed. The transmitter exits the bind mode automatically.
-
Check to make sure the transmitter and receiver functions are working correctly, repeat steps 1 to 3 (binding process) if any problems arise.
Follow the steps below to bind in one-way binding:
- Select [ANT 1 WAY] for RF standard of the transmitter, then put the transmitter in bind mode.
- Put the receiver in bind mode ( Refer to the description above for entering bind mode).
- When the LED of the receiver is in slow flashing state, the binding process should be completed. You need to manually put the transmitter to exit the bind mode. Then the LED of the receiver is solid on, indicating that the binding is completed.
- Check to make sure the transmitter and receiver functions are working correctly, repeat steps 1 to 3 (binding process) if any problems arise.
Note: Put the transmitter in bind mode first, then put the receiver in bind mode. If the binding is not completed within ten seconds, the LED of the receiver will enter its slow flashing state.
Instruction for Gyroscope function
This receiver has a built-in gyroscope and can be adapted to the ANT protocol
transmitter with the SVC (smart vehicle control) function. The smart vehicle
control function is to control the vehicle throttle and steering channel
intelligently through the gyroscope. It can ensure that the vehicle is in the
expected direction to maintain a better driving condition even in case of
bumpy roads or zigzagging. It is necessary to finish the parameter settings
related to this function at the transmitter side. Take FS-G7P transmitter as
an example to introduce the meaning of related parameters, including USE,
Neutral Calibration, ESP mode, Reverse, Steering Gain, Throttle Gain, Priority
and Gyroscope Calibration.
USE: Used to set to enable or disable the gyroscope function. By default,
it is disabled. You can assign a switch-like control to control the gyroscope
function (ON or OFF) by Control ASSIGN function.
Neutral Calibration: Used for gyroscope to calibrate the steering and throttle
neutral to make the best driving condition when the vehicle is driving
normally. Before enabling the smart vehicle control function, you need to
adjust the vehicle’s steering servo volume, neutral trim and throttle neutral
to the best driving condition. After completion, start the SVC(Smart Vehicle
Control) function for neutral calibration. It should be noted that the neutral
calibration is required after the adjustments of Trim and Curve. The steering
and throttle need to be set to the neutral position during the calibration
process.
ESP mode: Used to set the working mode of the gyroscope. It can be set to
Normal or Lock. By default, it is Normal mode. If it is set to Normal mode,
when the vehicle is yawing or steering, the gyroscope automatically provides
an opposite compensation to control the servo to keep it stable or prevent it
from drifting according to the angular velocity generated. The Lock mode is
only effective when the steering wheel is kept in its self-centering state,
(i.e., the vehicle yaws), the gyroscope will control the servo in the opposite
direction according to the yaw angle to make it travel back to the expected
direction. Note: If the steering wheel is non-self-centering in the Lock
mode, the operations are the same as those in Normal mode.
Reverse: Used to set the direction of the gyroscope in the mixing channel
direction. By default, it is set to Normal.
Steering Gain: Used to set the correction wheel to travel in the expected
direction. When the system detects that the vehicle body is about to move away
from the intended steering, it will automatically correct the body through the
wheel. Steering Gain is to adjust the correction strength of the wheels by the
system. 0%: No gyroscope assisting effect for the mixing servo. 100%: maximum
gyroscope assisting effect.
Throttle Gain: Used to set the strength of the gyroscope intervening in
the throttle adjustment. It is applied to the case that the throttle output is
reduced through mixing control by gyroscope to enable the car to change
directions quickly and safely when the vehicle turns with the throttle trigger
unchanged.
Priority: Used to set the control rate of Steering Gain when the vehicle
turns, that is, the turning radius. For example, in the direction turning by
using the traversing steering wheel, when the value is 0%, the mixing control
is the strongest, that is, the turning radius is the largest. When the value
is 100%, the mixing control is 0%, that is, the turning radius is the
smallest.
Gyroscope Calibration: Calibration is required when the gyroscope is enabled
for the first time or replaced. Before calibration, keep the model in a stable
and stationary state. Start the calibration. Then, the LED of the receiver
will be in twice- flash-one-off state. The calibration will automatically exit
if it succeeds. If it fails, a prompt is given in a pop-up window reminder.
Firmware update
The firmware of this receiver is updated through the FlyskyAssistant (Only version 3.0 or above is supported. The firmware of FlyskyAssistant is available on the Flysky official website).
This receiver can be updated via the following two ways:
- After the binding between the transmitter and the receiver (the LED of the receiver is solid on), connect the transmitter to the computer, then open the FlyskyAssistant on the computer to update the firmware.
- Connect the transmitter to the computer. Then put the receiver to enter the forced update mode by referring to the following three ways (The LED of the receiver operates in three-flash-one-off manner repeatedly). Afterwards, open the FlyskyAssistant on the computer to update the firmware.
• Power on the receiver while pressing and holding the BIND button for more than ten seconds, until the LED of the receiver operates in three-flash-one- off manner repeatedly, then release the BIND button.
• Power on the receiver first, then press and hold the BIND button for more than ten seconds, when the LED of the receiver operates in three-flash-one-off manner repeatedly, then release the BIND button.
• Connect the bind cable to the signals pins of the CH4 and BIND interface, then power on the receiver.
Failsafe
The failsafe function is used to output the channel value according to the
out-of-control protection value set by the user after the receiver loses its
signal and is out of control to protect the model and personnel.
It can also be set failsafe for each channel respectively. This receiver
supports two failsafe modes: ON and OFF
OFF It is no output for the interface of i-BUS/PPM/PWM.
ON To output the failsafe values set for the interface of i-BUS/PPM/PWM.
Notes:
- Because the S.BUS signal information contains failsafe flag bits, the failsafe information can be transmitted to the subsequent devices by the failsafe flag bits rather than by OFF state. The subsequent devices gives response according to the analysed information for the failsafe flag bits.
- For the signal PWM/PPM/i-BUS without failsafe flag bits, it supports the setting of the output signal to OFF in case of failsafe, transmitting the failsafe information to the subsequent devices by OFF state.
Attentions:
- 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 can result out of control. Unreasonable setting of the Failsafe may cause accidents.
- 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.
