FlyFishRC Atlas 4-Inch FPV Frame
The FlyFishRC Atlas 4 brings versatility to the sub-250g category, serving as both an efficient long-range cruiser and a capable park freestyle frame. Built around a Deadcat layout, the Atlas ensures your HD flight footage remains completely free of propellers. The frame utilizes high-end T700 carbon fiber paired with CNC aluminum camera plates, providing a great balance of lightweight agility and structural durability. To guarantee clean, jello-free video, it features silicone shock absorbers tailored for the DJI O4 Air Unit and standard 19/20mm cameras. The kit also includes a highly functional set of TPU prints, allowing you to seamlessly integrate an XT30 connector directly into the frame or mount a mini GPS module for long-range security.
Key Features
- Sub-250g Ready: Weighing just 55.6g fully dressed in TPU, the Atlas can slide under the 250g regulatory limit when paired with the right electronics and a lightweight battery.
- Deadcat Layout: The swept-back front arm design keeps 4-inch propellers completely out of your FPV feed, making it ideal for cinematic cruising and exploration.
- Advanced Vibration Damping: CNC aluminum camera plates paired with custom silicone shock absorbers effectively isolate high-frequency resonance from HD systems like the DJI O4 Air Unit.
- Smart TPU Integration: Includes an extensive TPU kit featuring arm protectors, an action camera base, a VTX/RX antenna mount, a mini GPS holder, and an integrated XT30 connector mount.
- Premium Hardware: Assembled with strong 12.9-grade hardware pre-treated with Loctite for a secure, maintenance-free build.
