Where To Buy?
The AOS 5 V2’s arm geometry has been revamped since version 1, with the second strut now meeting the main strut halfway along the arm. This alteration saves weight and enhances the frame’s resonance performance.
The frame now employs a three-point motor mounting system, according to the designer this improves arm durability during frontal impacts. This design modification also shaves off a bit of weight.
Electronics Mounting Options
The AOS 5 V2 boasts a range of electronics mounting options, with three positions (30mm, 25mm, and 20mm) supporting DJI Vista as well as the HDZero Freestyle VTX.
Top Plate, Motor, and Camera Mounting
The top plate has two positions for four battery straps, allowing a wide platform that enhances arm stiffness and durability. The three-point motor mounting system improves alignment, durability, and resonance performance. The camera plates accommodate DJI and other 19mm or 20mm cameras, providing protection without obstructing the view.
For electronics, consider using the Caddx Vista VTX with a UFL antenna and a 20mm x 20mm iFlight SucceX mini F7 stack. For carrying a GoPro, opt for larger motors like iFlight XING II 2208. Assemble the stack screws onto the main plate first and use thread locker or thick viscous grease on the screws to prevent loosening.
The AOS 5 V2 demonstrates exceptional noise performance and prop wash handling, enabling fewer filters and potentially turning off dynamic notch filters for improved flight performance.
While the AOS 5 V2 mitigates vibrations effectively, its complex design makes building and repairing more challenging. The lack of a proper GoPro camera mount and the need for a right-angle USB dongle to access the flight controller add to the hassle. However, the frame’s vibration-mitigating properties can reduce potential vibration issues.
The AOS5 V2 is an excellent FPV drone frame, offering versatility, ease of building, and outstanding performance. Its improved arm geometry, three-point motor mounting system, and various electronics mounting options make it an attractive choice for intermediate FPV drone pilots seeking to upgrade their equipment. However, keep in mind its somewhat complex design and potential durability concerns.
