The AOS 5 V5 O3 HD is a state-of-the-art 5-inch quad that prioritizes scientific engineering over traditional aesthetics. Featuring the AOS X-Cell anti-vibration mount, it reduces stack vibrations by up to 50% compared to previous models. This allows pilots to run higher PID gains and less filtering for an incredibly responsive, "connected" flight feel. Equipped with the DJI O3 Air Unit and XING2 2207 motors, it delivers 4K/60fps cinematic results with the agility of a pro racer.

Product Description

The iFlight AOS 5 O3 6S HD (specifically the V5 version) is a premium 5-inch freestyle drone designed in collaboration with engineer Chris Rosser. It is famous for its "resonance-free" design, which uses topology-optimized carbon fiber to shift frame vibrations away from the flight controller's sensitive frequencies.

Scientific Vibration Management: The frame uses a unique truss-arm design that is topology-optimized to be stiffer and lighter than traditional arms. By moving resonance points above the motor frequency, it virtually eliminates "prop wash" issues and "jello" in your video feed.
AOS X-Cell Stack Mount: The V5 introduces a patent-pending soft-mounting system for the FC/ESC stack. This mechanical filter prevents noise from ever reaching the gyro, allowing for a much cleaner tune and more aggressive flight performance.
7075 Aluminum Camera Cage: The front end features a high-strength aluminum cage that fits 19-20mm cameras. It includes an integrated soft mount specifically for the DJI O3 camera and is designed to be fully compatible with ND filters.
Zero Propellers in View: The "Squashed-X" geometry is specifically tuned so that even at wide FOV settings on the DJI O3, you will see absolutely no propellers in your footage from 5° to 60° tilt.
Steel Press-Nuts: To prevent the common issue of stripped threads in carbon fiber, iFlight has integrated steel press-nuts into the arm and stack mounts, making the frame much more durable and easier to repair in the field.
Flexible Battery Mounting: The top plate is designed to support both standard "lengthwise" battery mounting and "toilet tank" (perpendicular) mounting, allowing you to fine-tune your center of gravity based on your preferences.

The Pilot's Reality Check:

Performance over Durability: While the AOS 5 is very strong, its design is optimized for flight performance. If you are a beginner who plans on crashing into concrete repeatedly, a "tank-style" frame like the Nazgul5 or Roma F5 might be more forgiving.
Complex Build: Because of the X-Cell mount and truss arms, it has more parts than a standard freestyle frame. If you are building it from a kit, expect a slightly longer assembly time.

🤔 Frequently Asked Questions

What makes the V5 version different from previous ones?
The V5 introduces the AOS X-Cell anti-vibration mount for the flight stack, which reduces vibrations reaching the gyro by up to 50%. It also features a new 7075 aluminum camera cage that provides superior protection for the O3 camera and supports ND filters without any props appearing in the 155° wide-angle view.
Is it a "True-X" or "Squashed-X" frame?
The AOS 5 V5 uses a Squashed-X geometry. This design keeps the props out of the camera's view even at low camera tilts while maintaining the symmetrical motor spacing needed for predictable freestyle handling.
What is "Toilet Tank" mounting?
The frame supports two battery mounting styles. You can mount the battery lengthwise (traditional) or "Toilet Tank" style (perpendicular to the frame). Toilet tank mounting can improve the center of gravity and pitch responsiveness, which some freestyle pilots prefer for technical maneuvers.
How is the durability on the truss arms?
While the arms look thin, they are 6mm thick and use a truss structure that provides extreme rigidity against bending. The V5 also uses steel press-nuts in the frame, so you don't have to worry about stripping threads in the carbon fiber during repairs or arm swaps.
Does it come pre-tuned?
Yes. iFlight ships these with a custom AOS factory tune specifically designed to take advantage of the frame's low resonance. It typically comes with Betaflight presets that allow it to feel "locked-in" right out of the box.
