Frame

The iFlight Defender 25 has a compact and sleek frame that is made of 3K carbon fiber, a high-strength and lightweight material that provides excellent durability and rigidity. The frame consists of four arms, a bottom plate, a top plate, and a camera mount. The arms are 4mm thick and angled at 10 degrees for improved stability and maneuverability. The bottom plate is 2mm thick and has multiple holes for mounting the components. The top plate is 1.5mm thick and has a cutout for the camera. The camera mount is adjustable and supports different angles and sizes of cameras.

Flight Controller

The iFlight SucceX-D F7 TwinG flight controller is a powerful and reliable component that provides smooth and accurate flight control. It has a dual gyro system (MPU6000 and ICM20602) for redundancy and vibration damping, an F7 processor for fast and efficient calculations, and BetaFlight firmware for customizable and intuitive settings. The flight controller also has a built-in OSD (On-Screen Display) that shows real-time telemetry data such as battery voltage, current, and flight time. The flight controller supports 3-6S input voltage and has multiple UART ports for connecting peripherals such as GPS, crossfire, and LED strips.

ESC

The iFlight SucceX 15A BLHeli_S ESCs are compact and powerful components that control the speed and direction of the motors. They have a high-frequency (48MHz) and high-resolution (BLHeli_S) output for smooth and responsive throttle response. The ESCs also have a current sensor that measures the current consumption in real-time and protects the battery from over-discharge. The ESCs support DShot600, Oneshot125, and Multishot protocols and have a burst current of 25A and a continuous current of 15A.

Motor

The iFlight XING 1204 4500KV motors are small but mighty components that provide high thrust and efficiency. They have a hollow shaft design that reduces the weight and increases the cooling airflow. The motors also have NSK bearings and N52H magnets for durability and performance. The motors support both 3S and 4S LiPo batteries and have a maximum thrust of 250g per motor.

Propeller

The iFlight 2.5inch 3-blade propellers are optimized for the iFlight Defender 25 and provide a balance between speed, control, and efficiency. They have a durable and flexible polycarbonate material and a low pitch angle for high RPM. The propellers also have a reverse rotation direction for better stability and maneuverability.

Battery

The iFlight Defender 25 supports both 3S and 4S LiPo batteries with a capacity of 450mAh to 650mAh. The battery should have a discharge rate of at least 75C for optimal performance and longevity. The battery should also have a balance connector and a XT30 plug for easy and secure connection to the drone.

Camera and VTX

The iFlight Defender 25 comes with a Caddx Turbo EOS2 camera and a 5.8GHz 40CH 25/100/200mW VTX (Video Transmitter). The camera has a 1/3 inch CMOS sensor and a 1200TVL resolution for clear and vivid images. The camera also has a 2.1mm lens and a 160-degree field of view for wide and immersive shots. The VTX has a smart audio feature that allows you to change the frequency and power through your radio controller. The VTX also has a metal case and a MMCX antenna connector for durability and signal strength.

Features and Benefits of the iFlight Defender 25

The iFlight Defender 25 has many features and benefits that make it a top choice for aerial photography and videography. Here are some of them:
