System Functions
This section focuses on the functions and how to use them.
Channel Description
The transmitter outputs a total of 4 channels, which are allocated as follows:
- CH1：Steering Wheel
- CH2：Throttle Trigger
- CH3：Three-position Switch
- CH4：Key Switch
Note: By default the output of CH4 is 1000us, after which pressing the button will toggle between 1000 and 2000us.
Channel Reverse
This function is used to adjust the action direction of the servo or motor The ST.REV / TH.REV switches are the reverse buttons for CH1 and CH2. If the switch is up it indicates reverse, and the down indicates normal.
Trims
The ST.TRIM is the trims for CH1 (steering ),and can be multiplexed as Trims of CH3 ;
The TH.TRIM is the trims for CH2（throttle).and can be multiplexed as Trims of CH4 ;
For multiplexing switching mode, see [5.5 Mode Switching].
Adjustment range: -120us- + 120us;
ST.TRIM/TH.TRIM: counterclockwise adjustment to increase the trim value. The maximum value is 120 us.
ST.TRIM- / TH.TRIM-: clockwise adjustment to decrease the trim value. The minimum value is -120 us.
D/R
The ST.D/R is the trims for CH1 (steering ),and can be multiplexed as Trims of CH3 ;
The ST.D/R is the trims for CH2（throttle).and can be multiplexed as Trims of CH4 ;
For multiplexing switching mode, see [5.5 Mode Switching].
Adjustment range: 0-120%;
ST.D/R: counterclockwise adjustment to increase the ser vo amount . The maximum value is
120%.
ST.D/R: clockwise adjustment to decrease the ser vo amount . The minimum value is 0%.
TH.D/R: counterclockwise adjustment to increase the servo amount. The maximum value is 120%.
TH.D/R: clockwise adjustment to decrease the servo amount. The minimum value is 0%.
Mode switching
This function is for reusing the ST.TRIM and ST.D / R buttons for different channels (see [5.3 Trims], [5.4 D/R).
Function setting:
Under normal power-on condition, press the BIND button twice (within 1S) to switch between mode 1 and mode 2. By default, mode 1 is used.
Mode 1: R.LED is always on. G.LED is off. ST.TRIM is for CH1 trim. ST.D/R is for CH1 servo adjustment . TH.TRIM is for CH2 throttle trim. TH.D/R is for CH2 throttle servo adjustment .
Mode 2: R.LED and G.LED are flashing alternately. ST.TRIM is for CH3 trim. ST.D/R is for CH3 servo adjustment . TH.TRIM is for CH4 trim. TH.D/R is for CH4 servo adjustment .
Failsafe
This function dictates what the receiver will do in the event that it loses signal from the transmitter, this includes servo position etc.
Setup:
When the transmitter is switched on in normal communication state, keep the channel to be set at the position of the failsafe setup, and press and hold the BIND button for 3S. The G.LED flashes for 2S, indicating that the setting is successful. That is, when the receiver cannot receive the signal, it will output the set failsafe value.
Note: The fail-safe function has no default set at the factory and as such must be set manually. If no failsafe setting has been set, then the receiver will not output anything when signal is lost.
Beginner Mode
Beginner mode is designed for people new to the hobby.
In this mode the throttle will be limited to 50 percent, The channel range defaults to 1250~1500~1750us.
Setup:
To switch between beginner and normal modes press and hold the channel 4 button as the transmitter is turned on.
Note: By default, the system is set to normal mode. The GLED will flash slowly for 3 seconds during power on if the system is set to beginner mode.
ESC Parameter Setting
The Dial Switch on the transmitter is used to set ESC parameters, that is, the Dial Switch is located at different positions and the corresponding parameter values are different.
Setting Method:
There are three parameters can be set for the ESC, which are “Running mode”, “Battery type”, “Drag brake”, There are slide switches numbered 1 2 3 4 on the radio panel . The above parameters can be set by dialing down and up. The specific operation is as follows:
When No. 1 slide switch is on the down, it indicates that the operation mode is set to FWD / REV / BRK.
When No. 1 slide switch is on the up, it indicates that the operation mode is set to FWD/REV.
When No. 2 slide switch is on the down, it indicates that the battery type is set to Lipo.
When No. 2 slide switch is on the up, it indicates that the battery type is set to NiMH.
When No. 3 and No.4 slide switch are on the down, it indicates that the drag brake force is set
to 0%.
When No. 3 slide switch is on the down and No.4 slide switch is on the up, it indicates that the drag brake force is set to 50%.
When No. 3 slide switch is on the up and No.4 slide switch is on the down, it indicates that the drag brake force is set to 75%.
When No. 3 and No.4 slide switch are on the up, it indicates that the drag brake force is set to 100%.
Parameter Explanation:
- Running Mode
FWD/REV/BRK: This mode adopts “double click” reverse mode, that is, when the throttle trigger is pushed from netural range to the reverse area for the first time, the motor is only braking and will not reverse; when the throttle trigger is moved back to the netural range and pushed to the reverse area for the second time, it will reverse. This mode is applicable to general models.
FWD/REV: This mode adopts “one click” reverse mode, that is, when the throttle trigger is pushed from netural range to the reverse area, the motor immediately generates reverse action, which is generally applied to rock crawler. Parameter setting method:
When No. 1 slide switch is on the down, it indicates that the operation mode is set to FWD / REV / BRK.
When No. 1 slide switch is on the up, it indicates that the operation mode is set to FWD/REV. - Battery Type
There are LiPo and NiMH cells. The low-pressure protection value is different under different types. It can be set according to the actual use.
Parameter setting method:
When No. 2 slide switch is on the down, it indicates that the battery type is set to Lipo.
When No. 2 slide switch is on the up, it indicates that the battery type is set to NiMH. - Drag Brake Force
The drag brake means that when the throttle trigger moves from the forward or reverse area to netural range, it will produce certain braking force to the motor, the larger the value is, the greater the drag brake force is. Select proper braking force according to the actual situation.
Parameter setting method:
When No. 3 and No.4 slide switch are on the down, it indicates that the drag brake force is set to 0%.
When No. 3 slide switch is on the down and No.4 slide switch is on the up, it indicates that the drag brake force is set to 50%.
When No. 3 slide switch is on the up and No.4 slide switch is on the down, it indicates that the drag brake force is set to 75%.
When No. 3 and No.4 slide switch are on the up, it indicates that the drag brake force is set to 100%.
