I've tried to mount my M4 on a F450 frame, but it turned that M4 doesn't work well on that frame. No matter how I tune the PID, it oscillated with high frequency. So I decide to get a new frame for my M4.
The H4 frame is foldable which makes it easy to travel with. And there is enough space to install everything inside the frame. It's made of 1.5mm carbon fiber and 16mm CF tube. The motor-to-motor distance is 680mm. I want to know if anyone has tried AQ on similar frames, and how does it work?
