DarwinFPV HULK III Mini Waterproof RTF: Amphibious flight, ready to fly out of the box
In the world of FPV flying, many enthusiasts dream of experiencing the freedom of "flying in the rain and taking off from water"—yet they are held back by concerns: fear that equipment isn’t waterproof, worry that DIY waterproofing is too troublesome and unreliable. In the end, they can only limit their flights to sunny days and land. The DarwinFPV HULK III Mini Waterproof RTF is built to break this limitation: it combines the core capability of "waterproof and amphibious" with the convenience of RTF (Ready - to - Fly) that "requires no hassle and is ready to use right out of the box". Whether you’re a beginner just starting out in FPV or a professional FPV photographer looking to explore water - based flying, you can skip all complicated steps. After charging, you can directly unlock the novel FPV experience of "sky + water", truly letting flying return to the essence of "enjoying the moment".
Currently, the HULK III Mini RTF is available in two versions: the Analog Version and the O4Pro HD Version. The O4Pro HD Version supports 4K 120fps video recording.
Features
1. IP67 Waterproof Rating: Usher in a New Era of Amphibious Flight
No longer confined to land, it can take off and land directly on water, easily tracking and filming water-based extreme sports like surfing and jet skiing to capture dynamic moments. It can even submerge its camera underwater for shooting, providing you with an unprecedented and excellent underwater perspective, allowing you to experience a brand-new way of flying.
2. Top-Tier Configuration: Deliver a Stunning Visual Feast
The HULK III Mini is equipped with the new O4 PRO FPV transmission system, a 1/1.3'' image sensor, and supports 4K/120fps ultra-clear shooting. It also features electronic image stabilization for sharp and stable footage. Meanwhile, it boasts a max FPV transmission distance of up to 15 km and a transmission latency as low as 24ms, freeing your creativity from limitations and making exploration more enjoyable.
3. Powerful Performance: Unleash Speed and Passion
Featuring the new Seawater series seawater-resistant motors paired with a 6S high-voltage battery, the drone delivers a max thrust of 4.4KG. It can withstand level-7 winds and reach a top speed of 120 km/h, letting you fully experience the extreme speed charm of an FPV racing drone.
4. 4-Layer Armor Protection: 360° All-Round Hardcore Guard for Every Flight
The entire series adopts "cement" ultra-durable waterproof electrical components, a high-strength CNC aluminum alloy protective shell, a carbon fiber + roll cage design (covering key parts of the fuselage), and a high-toughness integrated injection-molded protective ring. Having undergone rigorous drop tests and actual flight tests, it can effectively protect the drone from damage even in extreme environments—this is visible hard power.
5. Multi-Purpose Drone: Save Money and Hassle
Darwin innovatively designs the O4 Pro FPV VTX in the form of an action camera, endowing it with action camera-like features such as waterproofing, heat dissipation, and sturdiness. You can easily switch it between different drone models just like replacing a GoPro, reducing the total cost of use and bringing true "O4 Pro FPV transmission freedom.
6. Safety Escort: It Stays With You
No matter how far it flies, it can always return to you. The entire series comes standard with GPS: if the remote control loses connection, the drone will automatically switch to rescue mode; when the video signal is lost, you can also manually switch to rescue mode. (GPS rescue mode is disabled by default at the factory; please refer to the relevant manuals before use.)
7. Flexible Installation: Adapt to Diverse Scenarios
It offers two battery installation methods (top and bottom) to easily handle different flight scenarios. For water flight: mount the floats on top and the battery at the bottom, enabling the drone to automatically correct its posture (flip back from an upside-down "turtle" position) after entering water. For regular flight: remove the floats and mount the battery on top, instantly transforming it into a racing drone.
8.The ELRS TX8 remote controller natively supports a variety of popular simulators It has a built-in ELRS 2.4G 100mW RF module and offers a control range of over 2KM, which can meet 90% of the usage scenarios for beginners, making it easier to enjoy the fun of flying.
9:The analog version is equipped with the EV800DM 5.8G 3-inch goggles (featuring lightweight portability + dual antennas for stable signal + 10ms low latency), while the HD version comes with DJI N3 goggles. Both options meet the demand for clear flying vision in different scenarios.
