Hi guys! We have an update with all the problem that we had last time. We tried all the possible connections for our heli before our test flight again. Here are the videos.
https://www.youtube.com/watch?v=6_AcxHYsHUU -> power supply for servo&engine is one, and another power supply for apm. it drifts to the left. and at the start the swashplate moves radically.
https://www.youtube.com/watch?v=3m2Q8FJOgFE -> power supply for servo&engine is one, and another power supply for apm. We connected it to the mission planner to determine the level. as you can see in the video, the level is very inaccurate.
https://www.youtube.com/watch?v=MmXD1JTqZHQ -> we tried the single power supply again. We changed the source of the gyro gain from ch6 to ch7. and used the old PID (all D are all 0)
So we are back in our old set up. The twitching is very minimal. So we are planning to fly it later. We will post the video of our test flight later. Hope it goes well. :)
