Flywoo Flylens 75 O4 Wide - 2S ELRS

Flywoo Flylens 75 O4 Wide is a lightweight 1.6" cinewhoop with DJI O4 Wide digital video transmission, suitable for cinematic flying indoors as well as calm flights outdoors. Thanks to the ducted propellers and low weight of 64.2 g without a battery, flying it is relatively safe even at home or near people. Even with the heaviest recommended battery, the takeoff weight remains well below the 250 g limit.

The frame consists of a 2 mm carbon plate supplemented with injected polycarbonate propeller guards. The whole structure is assembled with five screws, so replacing damaged parts is quick. The camera mount is attached on three rubber dampers, which minimize vibration transfer for smooth video and easy stabilization in Gyroflow. The video transmitter is housed in the lower part of the drone in a case made of durable PC material — so it is protected in crashes and at the same time better cooled. The battery compartment has a quick-release mount, and the package includes three TPU battery holders (550, 750 and 1000 mAh). The propulsion uses a reverse thrust configuration ("reverse thrust"), which, according to the manufacturer, brings more stable flight and slightly longer endurance. The power cable ends with an XT30UP connector with a fixed collar that prevents the cable from being pulled out of the battery.

Flight is controlled by the Flywoo GOKU F405 HD 1-2S 12A ELRS AIO V2 AIO board. The flight controller is built on an STM32F405 processor in BGA package with an ICM42688-P gyro, barometer for altitude measurement and 8 MB of memory for Blackbox. The board also integrates 12 A ESCs with Bluejay firmware and a serial ELRS receiver on 2.4 GHz. A separate 9 V/2 A BEC powers the video unit and prevents it from failing when voltage drops. The motors are connected via connectors, so replacing them does not require soldering. Propulsion is provided by ROBO 1003 14800 Kv motors combined with three-blade 1611-3 propellers with a 40 mm diameter.

Digital video transmission is handled by the DJI O4 Wide Air Unit. This is a DJI O4 unit with a different lens — instead of 117.6°, it offers 159° FOV, which is especially useful in confined interiors where a narrower view cannot cover the whole space. The 1/2" CMOS sensor records up to 4K/60 fps to 23 GB of internal memory; such footage replaces an external HD camera; the unit has no microSD card slot. The image is transmitted to the goggles in 1080 p/100 fps with a data rate of up to 60 Mbps; in Racemode, latency drops to as low as 20 ms. The transmission supports Canvas mode for classic OSD from the flight controller. An ND filter is included for filming in bright light.

The video unit is intended for use with DJI Goggles 3 or DJI Goggles N3 and DJI Controller 3. The unit can also be used with DJI Goggles 2 or DJI Integra and DJI Controller 2. In that case, however, Racemode is not available and the maximum bitrate is limited to 50 Mbps.

Recommended batteries are 2S with a capacity of 550-1000 mAh and an XT30 connector. Batteries are not included.

CLI and firmware

Important notice: The DJI O4 camera uses a new generation of gyroscopes that are more sensitive to vibration. This may affect the proper functioning of RockSteady and Gyroflow stabilization.
