DarwinFPV F4019R 4 Inch Folding Long Range FPV Drone Instruction Manual

DarwinFPV F4019R 4 Inch Folding Long Range FPV Drone

CAUTIONS

1. This AIO has an onboard SPI ELRS 2.4G receiver, and the default factory firmware is Beta fight version 4.4.2 supports TX module of ELRS_V3.0andabove.
2. 1504-3800KV motor max supports 3S battery, Must remember not to reverse the battery, otherwise it will burn the drone.
3. If the FC parameters are abnormal due to various reasons and cannot be used normally, you can go to Darwin FPV official store’s support page to obtain the official parameter configuration.
4. After receiving the FC, first connect to computer on Beta flight Configurator software to check whether the gyroscope and accelerometer are detected ,and whether the gyroscope attitude is normal.
5. Increase the throttle in Betalight software to ensure the normal rotation and correct rotation direction of the 4 motors, and then install the propellers to test flight;

Be sure to remove the propellers when pulling the throttle in Beta flight software to avoid accidents. After confirming the above precautions, you can install the propellers and start flying.

QUICK START GUIDE

Onboard SPI ELRS receiver binding

Connect the AIO to the computer and connect to Betaflight, enter the receiver configuration page, on page Click “Receiver Binding” in the lower right corner of the screen. At this time, the green indicator light of the AIO receiver will from slowly flashing to double flashing. After Waiting For the indicator light to turn solid, indicates that the binding is successful; after the binding is successful, the receiver will remember the binding information and will automatically connect , no need to re-bind.

We recommend checking whether the firmware of the TX module and the receiver are consistent before binding. If they are inconsistent, please update the firmware of the TX Module or AIO; Beta flight version 4.4 and above support ELRS_V3.0

Possible problems

After the receiver is bound to the transmitter, the receiver light keeps flashing slowly and the receiver cannot connect to the transmitter normally. The reason is that the packet rate of the transmitter and receiver are inconsistent. At this time, we can change the packet rate the transmitter or connect Betaflight modifies the packet rate of the SPIERS receiver to solve this problem.

The SPI ELRS receiver uses 250Hz by default, which can be solved by the following two methods

1. Modify the TX module packet rate:

2. Enter the Express LRS lua script

3. Modify the refresh rate of TX module to 250Hz
   

4. Modify SPI ELRS receiver packet rate:

You need to enter the Betaflight CLI and use the following command: set expresslrs_rate_index = [index] where [index] corresponds to the following: 500Hz = 0
250H z = 1
150Hz = 2
50Hz = 3
For example, if you want to switch the packet rate to 150Hz, you need to execute the following command in Betaflight CLI: set expresslrs_rate_index = 2 save

Transmitter lever switch confirmation

After successful binding, connect Betaflight, enter the mode option,and try to toggle the function switches of the transmitter. When The Yellow Cursor moves to the set range, the corresponding channel settings will be opened (If you order the RTF version, there is no need for binding, as the binding has been completed at the factory) .

Check motor steering

Enter the “Motor” page, turn on the “I understand the risks” option switch, and turn the motors one by one to check whether the direction of rotation is in line with the direction indicated by the motor steering diagram. Note: Be sure to remove all propellers before turning the motor to avoid accidents!

Propeller installation steps

Step 1： Place the 4 propellers with the words facing up, as shown the figure below:

Step 2:
Install the two propellers with the words D90S on the No2 and No.3 motors respectively; Install the two propellers with the words D90RS on the No. 1 and No.4 motors respectively; The correct propeller installation method is shown in the following figure:
