Compact 4K cinewhoop for
tight indoor fly-throughs discreet filming
FiwoX - The sub-100g 4K fly-through drone
The FiwoX is an ultra-light 4K FPV drone purpose-built for narrow indoor fly-throughs and discreet aerial filming. Its compact design can move through spaces that are inaccessible to conventional camera drones, opening up completely new possibilities for dynamic indoor shots.
Despite its extremely small size, the FiwoX delivers the precise and responsive handling required to navigate corridors, doorways and other confined environments. The carefully positioned DJI O4 Pro camera provides a completely unobstructed image without propellers in view.
With our recommended configuration—a naked DJI O4 Air Unit Pro paired with the camera in its original housing—the FiwoX remains below 100 g ready to fly, including the battery. This removes unnecessary weight from the Air Unit without sacrificing camera protection. The full O4 Pro configuration retains the Air Unit’s original housing, offering additional impact protection and improved cooling, but sits slightly above 100 g. Both configurations provide high-quality 4K recording.
Powered by 2S 580–680 mAh LiPo batteries, the FiwoX achieves approximately 2–4 minutes of flight time depending on the configuration and flying style.
Every FiwoX BNF is hand-built, conformal-coated, tested and individually tuned at our workshop in Switzerland. Please allow approximately three weeks for preparation before shipment.

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.
Premium components
Every component was selected specifically for low weight, responsive performance and reliable operation in demanding indoor environments. Each BNF is assembled, test-flown and individually tuned in Switzerland.
Conformal coating
All onboard electronics are conformal-coated during assembly, except for the DJI O4 system. This provides additional protection against moisture, dust and light splashes, but does not make the drone waterproof.
