Sub250 DollyFly 16 DJI O4 Pro - 2S ELRS

Sub250 DollyFly16 is a 1.6" whoop designed primarily for indoor flying and filming. The drone is equipped with the DJI O4 Pro digital video system, allowing high-quality recording in up to 4K resolution. The DJI O4 Pro camera is mounted on a holder connected to the frame via rubber dampers, which help minimize vibrations transferred to the camera for smooth footage and easier stabilization. The camera tilt is adjustable. The DJI O4 transmitter is accessible from the bottom, providing easy access to the USB port and microSD card. The drone is intended for smooth indoor flights or calm outdoor conditions.

Power is provided by the TAKER F411 AIO board, which combines the flight controller, ESCs, and an integrated ELRS 2.4GHz receiver. The flight controller runs on an STM32F411 processor and ICM42688-P gyro. The 12A ESCs use Bluejay firmware. Propulsion comes from Sub250 1103 14000Kv motors paired with Gemfan 1639 four-blade props. The frame is cut from 2mm carbon fiber with injection-molded prop guards. The battery holder and antenna mounts are 3D printed.

The drone weighs approx. 88g without a battery; with 2S 450–550mAh batteries, the all-up weight is around 120g. Flight time is about 3 minutes, depending on the battery and flying style.

DollyFly16 delivers a compact and lightweight cinewhoop with O4 Pro, tuned for smooth cinematic flights in tight spaces, offering up to 4K/120 fps recording, an adjustable camera angle, and a practical design with replaceable high-wear parts.
