BetaFPV Pavo Pico Brushless Whoop (DJI O3)

NOTE:

Kit contains a battery, which will be removed for international orders and replaced with an extra bag of props.

Bullet Point

• The split-design HD VTX mounting bracket is compatible with popular models like DJI O3 Air Unit, Walksnail Avatar HD Pro, and Caddx Vista. The side bracket, rubber damper vibration-damping design, lens holder, and antenna have all been reinforced to suppress low-frequency vibration and enhance the safety of HD VTX, ensuring a stable output of high-definition videos. Simply connect the VTX cable and complete the binding process to start flying.
• To safeguard the DJI O3 camera lens and maintain consistent high-definition video output during flight, both a lens filter and a lens protection mount are included.
• The battery slot and HD VTX mounting bracket duct height have been reduced to enhance the overall flying experience. DIY battery fixing methods are also supported, making them compatible with batteries of varying sizes and capacities.
• The new F4 2-3S 20A AIO FC V1 upgrades from F4 1S 12A FC V3, weighs only 5.92 grams, and is optimized for HD digital VTX. Its improved computing power, high response speed, and stable flight make it an ideal choice for HD whoops.
• The frame is constructed using PA12 material, known for its exceptional impact resistance and effortless installation process

HD Digital VTX System

Pavo Pico supports various types of HD VTX. DJI O3 and Walksnail Avatar Pro Kit both support HD digital VTX up to 1080P using dual-band transmission technology for better signal stability. The Vista Kit supports digital signal transmission for HD video up to 720P, with low latency and superior image quality performance. It's compact and lightweight, making it great for small drone installation, and compatible with various remote controls and monitors. The customized HD VTX mounting bracket has a split design, making it effortless to install for pilots DIY, and explore more possibilities while ensuring HD image quality.

ND Filter for DJI O3 Camera

BETAFPV ND Filter for DJI O3 Camera is specifically designed for the Pavo Pico Brushless Whoop Quadcopter. Meanwhile, the DJI O3 Air Unit ND Filters are tailored for the DJI O3 Air Unit and are capable of reducing the amount of light that enters the camera lens. With this feature, you can achieve slower shutter speeds or wider apertures when flying. These lightweight filters are crafted from high-quality optical class ensuring optimal image clarity and are too easy to install on the build. 

Pavo Pico Frame Kit

We used ultra-light PP material to make the HD VTX mounting bracket, increasing its toughness. The antenna fixing slot and frame have been fused to reduce damage risk, while the camera's installation height has been lowered with a protective printed part to limit its movable angle to within 30°. Additionally, an O3 filter can be used to protect the lens and enhance image quality. We have incorporated a unique rubber dumper vibration-damping design, used with GyroFlow stabilization software, which greatly enhances safety and ensures a smooth, HD image output. To achieve the best performance from the rubber dumper vibration-damping design, it is recommended to adjust it to a half-tightened state. This will effectively perform its role as a shock absorber without the need to fully tighten it. And The whoop quadcopter is presented with the installation bracket of the DJI O3 digital transmission original antenna.

And The whoop quadcopter package includes the DJI O3 HD Digital VTX Antenna Mount.

DJI O3 Vibration Problem

To tackle the challenge of vibration on many whoop drones, the DJI O3 unit is mounted on a carbon fiber plate with 4 rubber dampers. This innovative design ensures peak performance and perfect stability.

Troubleshooting:

To improve video quality when recording with DJI O3 HD VTX, turn off its electronic stabilization and use GyroFlow stabilization software.

When fixing the HD VTX bracket with M1.4*10 screws, ensure that the nut just touches the shock-absorbing ball.

The Jello effect may occur during the above installation due to 2 reasons:

• The VTX bracket is over-tightened with the screw and the rubber dumper is totally deformed. To solve this, make sure that the screw is tightened just enough to touch the shock-absorbing ball and keep the ball and bracket loose.
• If It is a large deformation of the frame or quadcopter blades, replace the frame or blades with larger vibrations if necessary.

Note: use acetate tape to bind motor wires and prevent them from drooping and interfering with the propeller's rotation.

Upgrade Low Profile Design

After collecting feedback through the BETA TEST, we lowered the height of the HD VTX mounting bracket and whoop duct from 60.6mm to 51.5mm and the battery compartment results in a more low profile on the cinewhoop. 

Pilots can further customize their cinewhoop with DIY options such as battery straps or printable components, allowing for compatibility with a variety of battery sizes. This enables pilots to tailor and enhance their cinewhoop to meet their specific requirements and preferences. Steps as follow:

Flight Controller

F4 1S 12A AIO Brushless FC V3, the FIRST flight controller designed specifically for HD VTX. This whoop quadcopter is equipped with STM32F405 chip for high-performance calculations. It weighs only 4.2 grams and includes a Serial ELRS 2.4G receiver, 16MB Black Box, Barometer, and Current meter. Designed for HD VTX, it also added support for external GPS through Betaflight 4.4.0

Flight Controller

We upgraded the FC from F4 1S 12A AIO FC V3 to F4 2-3S 20A AIO FC V1. The upgraded FC features an ESC with a pulse overcurrent capacity of 25A, ensuring stable operation of the flight controller even in the event of motor stalling. The addition of a 9V 2A BEC power supply ensures the stable operation of the DJI O3 HD VTX when the battery voltage is low. It also includes a DJI O3 6-pin PMU allowing for connection to HD VTX without soldering. It integrates features such as a 16MB black box, with support for GPS, external receivers, and other devices. The redesigned solder pad layout and USB connector make installation and maintenance easier and more convenient.

Note: The second batch of FC starts in August 2023. And If you use the F4 2-3S 20A AIO FC V1, the serial port of the SBUS receiver is UART5 while F4 1S 12A AIO Brushless FC V3 is UART6.

We also have extended the USB port to the end for easier parameter adjustment and wiring. A new DJI O3 6-pin PMU has been added for convenient installation and maintenance.

Power system

The 1102 14000kv motor brings stronger power and lower noise, delivering abundant thrust and impressive speed that enable effortless execution of aerial maneuvers. Paired with the high-performance Gemfan 45mm propeller, this power system achieves superb balance, ensuring powerful lift and stable flight, while also providing precise and responsive control. The combination of these power systems makes it an excellent choice for Pavo Pico, allowing pilots to easily accomplish filming tasks.
