here are a 1.8 year old video that i edited to show how are the video footage of high stability rotorcraft.
This is one of me first test with full-HD video cam.
As you can see, this platform is much more stable as ardupilot.
No wooble or vibrations.
Some balance in the video are due gimbal servos. I am using nicoleto gimbal.
This setup are using default PID.
OBS: from 2:00 to 3:00 the video are post processed to remove some wooble.
Today the platform is much more stable and using high speed servos on the gimbal
