After 2 years with the very successful ProTek series, iFlight continues to strive for a better flying experience and performance with the next upcoming innovative step. Let’s meet the Defender25.
Ultralight & Free to Fly
At sub 249g weight, our Defender25 doesn't require registration in most countries. The compact and lightweight design also makes it easy to carry and store. It will be your best travel buddy to redefine your FPV adventure.
Small But Mighty
The built-in 2.5inch propeller guards were designed to fly bold. You’ll experience a complete new creative freedom to fly whenever and wherever. The durable injection molded frame does not only prevent damage to your motors or propellers, but also protects the environment of small flight errors.
4K Stabilized Video with 155°Ultra-Wide Angle
Equipped with the latest tech from DJI, the O3 Air Unit HD transmission system. The Defender25 supports 4K video and shoots up to 155°super-wide FOV footage for stunning visuals. In addition, D-Cinelike color mode provides more creative freedom for color grading, allowing you to edit and adjust your footage. (Source DJI)
