Sub250 Huma20 O4 Pro - 4S ELRS

Sub250 Huma20 O4 Pro is a compact 2" Cinewhoop equipped with DJI O4 Pro digital video transmission. Thanks to the DJI O4 Pro unit, the drone can record high-quality video in up to 4K resolution, eliminating the need for an additional action camera. The camera is mounted using rubber soft mounts to minimize vibration transfer. Despite its size, the Huma20 uses powerful 1306 6000Kv motors, making it suitable for both indoor flying and faster outdoor flights. For durability, safe prop protection, and minimal air resistance, the prop guards are made from 2mm carbon fiber.

The Huma20 is powered by the Redfox A3 45A AIO board, which integrates a flight controller with an F722 processor, ICM4266 gyro, barometer, and 45A ESCs with BlHeli_32 firmware. The propulsion system consists of Sub250 1304 6000Kv motors, HQProp 2x2.2x4 propellers, and a 4S battery.

Recommended batteries are 650–850mAh 4S with XT30 connector.
