Description
Compact 4K cinewhoop for
tight indoor fly-throughs discreet filming
FiwoX - The sub-100g 4K fly-through drone
The FiwoX is an ultra-light FPV drone frame purpose-built for narrow indoor fly-throughs and discreet aerial filming. Its compact design allows builds that can move through spaces inaccessible to conventional camera drones, opening up new possibilities for dynamic indoor shots.
Designed around the DJI O4 Pro camera, the FiwoX positions the camera for a completely unobstructed image without propellers in view. Its compact layout provides the foundation for a lightweight, responsive drone suited to corridors, doorways and other confined environments.
With our recommended configuration—a naked DJI O4 Air Unit Pro paired with the camera in its original housing—a completed FiwoX build can remain below 100 g ready to fly, including the battery. This reduces Air Unit weight while retaining camera protection. A build using the Air Unit’s original housing offers additional impact protection and improved cooling, but sits slightly above 100 g. Both configurations support high-quality 4K recording.
The FiwoX is designed for builds powered by 2S 580–680 mAh LiPo batteries, with approximately 2–4 minutes of flight time depending on the components, configuration and flying style.
This product includes the FiwoX frame only. Electronics, camera, motors, propellers and battery are not included. Assembly, setup and tuning are required.

SUB-100 G
In the Naked O4 Pro configuration, the FiwoX stays below 100 g ready to fly, including the battery. Its exceptionally low weight makes it highly agile and ideal for tight indoor environments.
Naked or full O4 Pro
Choose our recommended setup—a naked DJI O4 Air Unit Pro paired with the camera in its original housing—for the best balance of low weight and protection. This configuration stays below 100 g ready to fly, including the battery, while keeping the camera protected.
The full O4 Pro configuration retains the Air Unit’s original housing as well, providing additional physical protection and improved heat dissipation, but brings the FiwoX slightly above 100 g. Both configurations record in 4K.
No Props in View
The camera position and frame geometry keep the propellers completely outside the recorded image for a clean 4K view. Our dedicated camera soft-mounting system isolates the O4 Pro camera from frame vibrations, keeping its sensitive gyro data clean and the footage free from gyro-related stabilisation issues. The result is stable, usable footage even during tight fly-throughs and dynamic manoeuvres.
Carbon-Fibre Landing Skid
The lightweight carbon-fibre landing skid provides a stable base and keeps the camera clear of the ground during take-off and landing, while adding minimal weight to the drone.
Integrated XT30
The integrated XT30 connector provides a clean and secure battery connection without loose cables around the frame. The FiwoX is designed for 2S 580–680 mAh LiPos and offers approximately 2–4 minutes of flight time, depending on the setup and flying style.
