FlyFishRC Atlas 4 LR O4 Pro FPV Frame Kit - Black

FlyFishRC Atlas 4 O4 Pro LR FPV Frame

The FlyFishRC Atlas 4 is a lightweight 4-inch FPV frame built for pilots who want versatility, low weight, and a clean flying experience. At just 55.6 g with the full TPU set installed, it is a serious option for sub-250 g builds while still offering the durability and practical features needed for everyday FPV flying.

This is not just another long-range frame. The Atlas 4 is designed to extend flight time, but its real advantage is flexibility. It feels just as at home on efficient cruising flights as it does during fun freestyle sessions in the park. Thanks to its smart balance of strength, weight, and layout, it delivers a smooth and confidence-inspiring experience in the air.

The frame uses a well-thought-out deadcat geometry to help keep props out of view, giving you a cleaner FPV image. FlyFishRC’s signature CNC aluminum camera side plates and silicone dampers add both strength and better camera support, especially for modern HD systems. The result is a compact 4-inch platform that looks clean, flies great, and is easy to adapt to different setups.

Another big advantage of the Atlas 4 is its hobbyist-friendly design. The included TPU parts help protect the frame and simplify your build, while the XT30 mounting solution can be integrated directly into the frame for a neat wiring setup. If you prefer a different battery lead routing style, the frame also gives you the freedom to route the cable from the rear, front, or side depending on your build preference.

Whether you are chasing a true sub-250 g setup or building a more powerful 4-inch machine, the Atlas 4 gives you room to choose your own direction. Pair it with an AIO 30–40A flight controller, DJI O4 Pro, Vista, Walksnail, or an analog system, and tune the final character of the quad with your preferred motor and battery combination.
