Atlas 4 LR FPV Frame

FlyFishRC Atlas 4 – New, Ultra-Light 4" Frame

Atlas is a new, exceptionally lightweight 4-inch frame from FlyFishRC, weighing only 55g. It's a strong contender in the sub-250g category!

Unlike traditional long-range frames, Atlas stands out with its versatility. It offers longer flight times, but its true strength lies in its ability for dynamic freestyle. FlyFishRC has extensively tested it in park FPV sessions, where it performed excellently!

Thanks to a thoughtful design that combines lightness with robust durability, Atlas handles any conditions. Equipped with CNC aluminum plates, silicone dampeners, and a deadcat layout, it ensures a stable, smooth flight without props in view.

Open and Flexible Design

In line with FlyFishRC's philosophy, all 3D models are available as open-source on our Thingiverse, allowing for modifications.

Atlas weighs only 55g with a full TPU set, which includes:
✔ Arm guards
✔ Sport camera mount
✔ VTX and RX antenna mounts
✔ Mini GPS holder
✔ XT30 mount for frame integration

Don't want integrated XT30?
For full flexibility, two additional slots have been cut into the top plate – at the back and front, just behind the camera mount. You can also simply route the cable from the side.

Atlas gives you complete configuration freedom:

• Want sub-250g? Choose AIO 30-40A, DJI O3/Vista/Walksnail/Analog, FlyFishRC 1804 motors, and a 6S 380mAh battery – you'll easily stay under 250g!
• Looking for a stronger setup? FlyFishRC 2004 motors and a larger battery provide more power and flight time!
