 iFlight Defender 25 Review : A Lightweight Sub-249g FPV Drone with DJI O3 Air Unit

Introduction:
iFlight has introduced the iFlight Defender 25, a sub-249g FPV drone that combines agility and advanced features for enthusiasts and professionals alike. With its DJI O3 Air Unit, 2.5" propellers, and customizable battery options, this drone offers an exciting aerial filming experience. In this article, we will explore the key features and specifications of the iFlight Defender 25 and discuss its potential applications in the world of FPV drones.

Design and Propulsion:
The iFlight Defender 25 features a sleek design with 2.5" propellers protected by prop guards, making it ideal for indoor flying, close-quarters filming, and practice sessions. The inclusion of short feet aids takeoff from various surfaces. The drone shares similarities with the DJI Avata, albeit with a lighter weight. The Defender 25 weighs 410g with the smaller battery, and without a battery inserted, it weighs 180g.

Battery Options:
The iFlight Defender 25 offers two battery options to suit different flight requirements. The stock 550mAh 4S battery keeps the total take-off weight under 249g and provides a maximum hover time of approximately 6 minutes. Alternatively, the endurance 900mAh 4S battery, with a total take-off weight under 280g, extends the hover time to around 10 minutes. These custom 4S LiPo batteries feature a quick-release mechanism and are housed in a protective plastic enclosure, ensuring safety and impact resistance.

DJI O3 Air Unit and Camera:
Equipped with the DJI O3 Air Unit, the iFlight Defender 25 captures high-quality footage with low-latency transmission and impressive video recording capabilities. The O3 Air Unit offers a 1080p 120fps signal for DJI goggles, while also supporting 4K 60fps video recording in the flat D-Cinelike color profile. The camera is mounted on a vibration-damped mount, reducing motor vibrations and providing smoother footage for enhanced post-stabilization.

Additional Features and Connectivity:
The iFlight Defender 25 includes features such as turtle mode, allowing the drone to flip itself when landed upside down. It also features a camera mount on the back, enabling users to attach lightweight cameras like the GoPro, Insta360 GO II, or Caddx Peanut. The drone's dimensions are 158x155x69mm, and it offers a convenient USB-C port for easy connectivity to a computer. With a maximum speed of 100kph and a flight distance of 2-3 km, the drone delivers an exhilarating flying experience.

Price and Availability:
The iFlight Defender 25 is available for pre-order on the iFlight online shop. The base version, priced at $539.99, is designed for use with the DJI FPV remote controller 2. However, iFlight also offers versions bundled with compatible receivers for those who prefer alternative radio systems. These versions include the TBS Crossfire NANO RX ($568.99), Commando 8 ELRS 868/915MHz RX ($555.99), and Commando 8 ELRS 2.4GHz RX ($555.99). Each iFlight Defender 25 purchase includes a 550mAh battery, a charging adapter board, and spare 2525 propellers. Additional batteries can be purchased separately to extend flight time.

Conclusion:
The iFlight Defender 25 sets a new standard for lightweight FPV drones, combining the advantages of the DJI O3 Air Unit, agile flight performance, and customizable battery options. Its compact size and propeller guards make it suitable for indoor and light outdoor flying.

Whether you are an FPV enthusiast or a professional aerial filmmaker, the iFlight Defender 25 offers an impressive range of features and versatility. Explore the possibilities of immersive FPV flight and capture stunning footage with this innovative sub-249g drone.
