WalleFPV Naked O4 Pro\Ultralight O4 Pro

Hello everyone, today we're introducing WalleFPV's second product, the Naked O4 Pro.

The Eagle 2 weighed 69.5g during prototype testing, and its actual production weight is 72g. Adding the 31.5g battery, its takeoff weight exceeds 100g. At its launch, the Eagle 2 was the smallest FPV drone equipped with the O4 Pro, achieving good results in power and range, and customer feedback has been very positive.

However, in the future, around 2026, some regions will impose stricter restrictions on FPV drones that can fly without declaration, requiring a takeoff weight below 100g.

At the same time, we wanted to upgrade the Eagle, making it the lightest and smallest FPV drone equipped with the O4 Pro, while further improving its power and range. Therefore, we officially began the design and development of the Naked O4 Pro in July.

After multiple design improvements and extensive testing, the WalleFPV Naked O4 Pro is about to be released. Testing is basically complete, and it is currently in the trial production stage, with an expected shipping date of the end of November.

We've also designed a filter kit for the Naked O4 Pro, including UV, ND8, ND16, and ND32 filters.

The O4 Pro, including the antenna and camera screws, weighs 33.4g, while the Naked O4 Pro weighs only 20g, achieving a 13.4g weight reduction. This is a significant improvement for FPV dramas under 2.5 inches. The weight reduction allows for more power and longer battery life.

The Naked O4 Pro case kit uses 7075 aerospace-grade aluminum alloy, offering good strength while keeping the weight around 2.5g. Its dimensions are also reduced to 31.4*31.4*12mm, smaller than the O4 Pro, making it easier to install on a Micro FPV camera.

All mounting holes and screws are identical to the O4 Pro, so there are no frame kit compatibility issues. You can purchase the case kit to upgrade your O4 Pro for better power and longer battery life.

We also customized a 60mm cable (for the camera), making it more convenient and lighter for use with FPV drones under 2 inches.

Some might ask why not just use the 8.2g O4 Air Unit, which is lighter and can shoot 4K video. However, the DJI O4 Air Unit Pro features a 1/1.3-inch sensor, supports 4K/120fps video recording, and boasts a 155° ultra-wide-angle lens, 10-bit D-Log M color mode, and multi-mode video stabilization—features the O4 Air Unit lacks.
