AOS 7 EVO V1.2

A range of frames AOS was developed by FPV youtuber Chris Rosser, who is best known for testing parts for drones. AOS frames are developed based on blackbox data and simulations of vibration and resonant frequencies. Each part of the frame has been optimized to shift the resonant frequencies above the frequency of the motors. As a result, less vibration goes into the controller, less filtering is needed, and it is possible to raise the PID controller values, which improves flight performance and minimizes propwash.

The AOS 7 frame is suitable for building a long-range drone with 7" propellers. The frame is distinguished by its design, with V-shaped split arms and made of 8mm thick carbon fiber. As a result, the frame is not susceptible to vibration and can be used for freestyle with larger and heavier cameras in addition to long-range flights. The frame can be built with analog and digital video transmission. Comfortably accommodates DJI O3, Caddx Vista, Walksnail Avatar and HDZero 1W. The frame body can hold up to 3 stacks of 30.5x30.5/20x20mm mounting holes. There are cutouts in the top plate for mounting the Lipo battery with three straps. The camera is mounted in carbon sidewalls that protect the camera. The camera is held in TPU inserts that can hold cameras of different sizes. There are also two holes for SMA connectors on the top plate. The antennas from the video transmitter can thus be mounted in the center of the frame above the battery.
