Quadcopter IFLIGHT Defender 25 4S HD DJI 03

Ultra-light and flight-ready

Weighing less than 249g, our Defender25 does not require registration in most countries. Its compact and lightweight design also makes transport and storage easy. It will become your best travel companion to redefine your FPV adventure.

Small but mighty

The integrated 2.5-inch propeller guards are designed for bold flying. You will feel a whole new creative freedom to fly anywhere and everywhere. The durable injection-molded frame not only prevents damage to your motors or propellers but also protects the environment from minor flight mistakes.

Equipped with the latest technology from DJI, the O3 Air Unit HD transmission system. The Defender25 supports 4K video and shoots with an ultra-wide field of view of up to 155° for stunning imagery. Additionally, the D-Cinelike color mode provides more creative freedom for color grading, allowing you to edit and customize your footage. (Source: DJI)
