Product overview
The DarwinFPV HULK III Mini is a flight platform for FPV racing and filming around water. Its IP67 waterproof design supports direct water takeoff and landing, with the camera able to dip underwater for additional shooting angles. Physical protection combines waterproof electrical components, a CNC aluminum alloy shell, carbon fiber and a roll cage around key fuselage areas, plus an integrated injection-molded protective ring. Seawater series motors paired with a 6S high-voltage battery deliver a maximum thrust of 4.4KG; top speed is 120 km/h and wind resistance is level 7.
Video equipment depends on the selected configuration: analog, O4 Pro, or a version without O4 Pro. The O4 Pro configuration combines a 1/1.3-inch sensor, 4K/120fps recording and electronic image stabilization, with FPV transmission reaching up to 15 km and latency as low as 24ms. Its transmitter uses an action-camera-style housing with waterproofing and heat dissipation, designed to move between drone models. The version without the DJI O4 unit includes an empty waterproof enclosure. Each video configuration has PNP and BNF variants, with an ELRS2.4G receiver included in BNF.
Battery placement changes with the operating arrangement. Water flight uses floats on top and the battery underneath, enabling automatic correction from an upside-down position after entering water. For regular flight, the floats are removed and the battery moves to the top. GPS is standard throughout the series, but GPS rescue is disabled at the factory and requires setup before use. Rescue supports automatic activation after remote-control connection loss and manual selection after video loss. Selectable bundles provide two or four 6s 1300mAh waterproof batteries, propeller packs, combined packages, or no bundle.
