DarwinFPV FoldApe4 O3 Frame

Ultra-portable design meets precision engineering. The DarwinFPV FoldApe4 O3 Frame is a 4-inch micro long-range FPV drone frame that features a foldable structure, shrinking its size by 70% for easy storage and transport. Whether you're capturing stunning aerial shots or cruising the skies, this frame ensures your build is both compact and ready to go. The lightweight 51g frame keeps your drone under 250g takeoff weight, making it compliant with regulations in most countries.

Designed to work with all mainstream video transmission systems—whether analog, DJI O3, RunCam Link WASP, or Walksnail Avatar—the FoldApe4 is as versatile as it is portable. It's also optimized for mounting a bare GoPro, with a reserved GPS installation location to enhance navigation and signal reception.

To tackle issues like vibration and arm rigidity, DarwinFPV has introduced carbon fiber propeller clamps and secure arm structures. Even under intense freestyle moves or crashes, the arms won't fold back mid-flight. Pre-assembled for your convenience, this frame is ready to go right out of the box—ideal for both novice pilots and seasoned pros looking for an efficient and travel-friendly setup.

Key Features:

• Foldable Design: Reduces its size by 70% when folded, allowing easy storage without needing to remove the propellers. Fits right in your pocket for maximum portability.
• Pre-Assembled: The frame arrives fully assembled, saving time and eliminating assembly guesswork, perfect for beginners.
• Durable Arm Structure: Fixed with two screws when unfolded, ensuring the arms stay rigid even after a crash or during intense maneuvers.
• High-Precision Prop Clamps: Carbon fiber propeller clamps with metal bushings provide ±0.05mm accuracy, reducing vibrations and enhancing durability.
• Ultra-Lightweight Frame: Weighs just 51g, making it lighter than similar 4-inch frames, contributing to longer flight times and easier handling.
• Wide Compatibility: Compatible with major VTX systems (analog, DJI O3, RunCam Link WASP, Walksnail Avatar), plus GPS and GoPro mounting capability.
• Re-Optimized Design: Features a refined DC structure that eliminates front-rear moment asymmetry for better flight stability and feel.
