Meet the FlyFishRC Atlas 4, a lightweight marvel designed to dominate the sub-250g long-range category without sacrificing freestyle durability. Weighing in at a mere 55.6g (fully built with TPU parts), the Atlas 4 is a formidable 4-inch platform that bridges the gap between endurance cruising and park ripping.

Sub-250g Long Range

The Atlas 4 empowers you to set your own rules. For a compliant Sub-250g build, pair it with 1804 motors and a 380mAh 6S battery. Craving something “spicy”? Step up to 2004 motors for increased power and agility. Its Deadcat Geometry ensures no propellers appear in your view, making it an ideal choice for cinematic cruising with the DJI O4 Pro Air Unit.

O4 Pro Ready & Jello-Free

Engineered for modern HD video, the Atlas features FlyFishRC’s signature CNC Aluminum Camera Plates. These are paired with custom Silicone Shock Absorbers specifically designed for the O4 Air Unit, isolating the camera sensor from high-frequency vibrations to ensure buttery smooth, jello-free footage.
