"I found the root cause: The Multistar ESCs are loosing sync with the Multistar motors (hello HobbyKing). No stuttering with Turnigy Plush. But those are slow at regulating RPM, so I am looking for fast ESCs that work with those motors."
"The bad sound of the motors is _because_ of the oscillations.
Regardless: I don't get them with props removed. So it has to be some resonance between the props and the Pixhawk coupled over flexing frame. Will have to stiffen the frame.…"
I am working on a 1.2m Quad with Pixhawk. First I had problems with the green Turnigy Multistar ESC, but after flashing SimonK they work very smooth and sensitive.Now the problem: When increasing yaw over 50% the two slower rotating motors start to…
See video: https://www.youtube.com/watch?v=7byJNPC09FEMy setup: The APM Power Module does not power the motors, just the Pixhawk via the thin cables and it delivers 5V via an UBEC to the PWM output lane so that the OPTO ESCs get voltage. The motors…
"So what goggles can be used for stereo display of those images?
Oculus Rift would be awesome, but it doesn't have analog in so it needs a fast analog-digital converter."
