1/ Drone Introduction

Review: Flywoo Baby Quad - Tiny Whoop Sized Drone Carrying GoPro

Flywoo has designed its smallest quadcopter to date, the Firefly Baby Quad, to push the boundaries of carrying a camera on the smallest possible platform. This nano-sized FPV drone is designed to carry an Insta 360go or SMO 4K camera for action flying.

Weighing in at just 59g, the Firefly Baby Quad is small, flexible, and stable, yet full of power and offers unmatched control. Pilots can quietly enjoy the fun of shooting video without jelly. The Baby Quad is equipped with a GOKU F745 13A STACK and 4pcs ROBO 1202.5 5500KV motors, providing quiet, stable, flexible, and long flight time characteristics. It is perfect for indoor and outdoor recording of every beautiful flying moment.

Configuration and Mapping:

If using a DJI remote control, turn on UART4 RX and turn off UART1 RX. Set the receiver protocol to SBUS.

• UART1: TBS/R9M/XM+/DSMX/SBUS receiver
• UART2: NULL
• UART3: VISTA OSD TX/RX
• UART4: VISTA SBUS RX (Only use DJI remote control to turn on, and turn off RX1)
• UART5: NULL
• UART6: NULL
• UART7: NULL

3/ Receiver Binding

TBS NANO 915:

When the USB is connected, the green light of the receiver flashes. Bind according to the picture operation. YouTube Guide

ELRS 2.4G RX:

Bind procedure:

1. Supply power to the EL24E/EL24P rx, wait until the LED on the RX is off, immediately turn off the power, and then repeat the above steps. When the RX is powered on for the third time, the LED light will start to double-flash, indicating that the RX has entered the binding mode.
2. Insert the 2.4G ELRS TX into the Radio transmitter, and choose External RF mode to CRSF protocol. Then you can find the ELRS menu from the Radio systems (Need to copy the ELRS.LUA file to the SD-Card tools first). Enter into ELRS and press [Bind]. The LED on the RX module will become solid if bind successfully.

Receiver LED status meanings:

• EL24E/EL24P RX: LED solid means bind successful or Connection established; LED double-flash means in bind mode; LED flash slowly means no signal connection from the TX module; LED flash fast means in WIFI hotspot mode. You can connect the WIFI of the RX and upgrade firmware of the RX via visiting 10.0.0.1 from the web browser (password: expresslrs).

R9MM FCC ACCESS OTA:

Make sure your remote control supports the ACCESS protocol, then follow the link to register and bind: YouTube Guide

If the remote control is ACCST protocol, please bind as follows:

1. Put these two files into the firmware directory of the SD card of the remote control: R9MM firmware: FW-R9MM-ACCST_v20190201, R9M TX module: FW-R9M-ACCST-20190117.
2. Insert the R9M TX module and write the firmware you need.
3. To write the firmware of the R9MM receiver, you need to remove the R9MM receiver and then write the firmware by connecting to the S.PORT port.
4. After both R9M TX and R9MM RX are written into the ACCST firmware:
   Binding method:
   1/ Press and hold the button of RX, power on, the red and green lights are always on.
   2/ Then after R9MM selects binding, RX red light flashes, and then exit.
   3/ RX is powered on again, and only a green light is displayed, indicating that the binding is successful.

XM+ Receiver:

1. Press the XM+ receiver button, USB power supply, the red and green lights are always on.
2. The remote control turns on the binding mode, the green light flashes to indicate successful binding. Turn off and restart.
3. Then set the corresponding serial port and receiver protocol to ensure the normal output of each channel of the receiver.

4/ Mode Setting:

Set the ARM switch and flight mode switch. AUX* corresponds to the remote control switch, and the yellow area mark is turned on.

Receiver Configuration:

Please refer to the receiver chapter of the documentation. Configure serial port (if required), configure channel endpoints/range on TX so that all channels go from 1000 to 2000. When TX is off or out of range:

IMPORTANT: Before flying, read the failsafe chapter of the documentation and configure failsafe.

Channel Mapping:

• Roll [A]: 1500
• Pitch [A]: 1500
• Yaw [R]: 1500
• Throttle [R]: 1000
• AUX 1: 1000
• AUX 2: 1350
• AUX 3: 2000
• AUX 4: 1500
• AUX 5: 1500
• AUX 6: 1500
• AUX 7: 1500
• AUX 8: 1500
• AUX 9: 1500
• AUX 10: 1500
• AUX 11: 1500
• AUX 12: 1500

Arming and Flight Modes:

• ARM: AUX 2 (Min: 1375, Max: 2100)
• ANGLE: AUX 2 (Min: 1700, Max: 2100)
• HORIZON: AUX 2 (Min: 1700, Max: 2100)
• HEADFREE: AUX 2 (Min: 1700, Max: 2100)
• FAILSAFE: AUX 2 (Min: 1700, Max: 2100)

Remember to save your settings using the Save button.

5/ Motor Test:

Unload the propellers. Test the rotation direction of the motors. Turn on the safety switch and test the rotation of the motors one by one.

6/ VISTA Activation and Binding

Tip: For convenience of use, VISTA has been activated by default at the factory and updated to the latest version of the firmware. The BNF version can be used directly without updating again. YouTube Guide

Motor Test in Betaflight Configurator:

The image shows the motor layout (1-4) and the corresponding sliders in Betaflight Configurator. Ensure motors spin in the correct direction as indicated by the arrows. The sliders allow for individual motor testing.

VISTA Activation:

The image shows a red circle indicating a button on the DJI Goggles and another red circle indicating a small component on the VISTA unit, likely related to activation or binding.

7/ Flight Firmware Upgrade and Write Default CLI

Activate DFU mode:

The Betaflight Configurator will display a message to enter DFU mode. If it does not enter DFU mode, the driver may not be installed. The driver can be installed using IMPULSE RC software. Download link: ImpulseRC Driver Fixer

Then load the local HEX firmware and wait for the flashing to complete. A green progress bar indicates completion, and DFU will become a COM port.

Write CLI Commands:

After the connection is entered, it will be a blank interface. You need to write CLI commands. Factory CLI LINK: https://flywoo.net/pages/manual

If the command is not restarted after writing the command, please write SAVE and press Enter to save, and the FC will restart.

Firmware Flashing:

The images show the process of selecting the correct firmware for the flight controller (e.g., F745NANO, QUAD LR Analog, QUAD LR HD) within the Betaflight Configurator and initiating the flashing process.

Finalizing Setup:

After flashing and applying CLI commands, all functions of the FC should return to normal. The Betaflight Configurator interface shows the status of the flight controller, including arming status, firmware version, and sensor data.
