Functional FPV drone weighing less than 249g

iFlight Defender 25 is a lightweight and stable drone of the cinewhoop type, created for flights in places requiring special care. With a take-off weight not exceeding 249g, the device complies with many aviation regulations, making it a practical choice for recreational and semi-professional use. This model integrates the advanced DJI O4 system, offering high-quality HD preview and the ability to record video content in 4K resolution. It is a BNF (Bind-and-Fly) type drone, which allows you to quickly prepare for flight when paired with a compatible controller such as the iFlight Commando 8.

Blitz D25 F7 AIO design and integrated propeller guards

The construction of the defender25 model is based on a frame with durable propeller covers, which protect both the device and the environment during FPV flights inside buildings. At the heart of the electronics is the advanced Blitz D25 F7 AIO controller. The AIO (All-In-One) chip integrates F7 FC and efficient ESC on a single board, which allowed for significant weight reduction and optimization of space inside the housing. This configuration ensures stable control and adequate power for the drive powered by 4S packages. The design of the defender 25 has been thought out so that servicing and replacement of elements is as easy as possible for the user.

DJI O4 Air Unit Pro System and 4K Video Quality

The 4S HD version is equipped with the latest DJI O4 Air Unit Pro, which redefines the standards of digital transmission in drone of this class. This system provides a crystal clear HD image transmitted directly to goggles such as Goggles 2 or newer DJI models. The camera allows you to record stable 4K shots while maintaining a wide field of view, which is crucial in FPV productions. Thanks to image stabilization and high bitrate, the iflight defender 25 is a suitable alternative for larger units, while maintaining agility similar to DJI Avata devices, but in a more open and configurable form.

Innovative power system and 900mAh battery

A unique feature of defender25 is the dedicated battery mounting system, which eliminates the need for traditional Velcro. The special latching mechanism facilitates quick cell replacement, which is very helpful during intensive FPV sessions. The user can choose from packages with a capacity of 550mAh for the lowest weight or 900mAh for an extension of the time spent in the air. The set also includes a adapter, which allows you to charge the batteries with standard model chargers. The entire 4S power system has been optimized for engine performance, which translates into smooth and predictable flight.

Additional functions and GPS safety

Despite its small size, iflight took care of equipping the drone with the GPS module. This feature allows for ongoing monitoring of the device’s position and supports rescue systems in the Betaflight software, which increases safety during outdoor flights. The Dron also has a built-in ELRS receiver (ExpressLRS), which in combination with the Commando 8 ELRS radio provides a stable control connection over long distances. Defender 25 is a tailored solution for people who need equipment ready to work in difficult spaces, where every gram of take-off weight and FPV control precision counts.
