My build is a big coaxial octocopter (26 inches folding prop) running a Blue Cube (hard mounted) with 3.6.7 copter version. Its vibration behavior degrades significantly whenever there is high level of wind and gusts (>20 km/h). I will give you an example of three repetitions of the same auto mission, with three different wind/gust levels.
As you can see, the same copter can have between 0 clip with no wind up to 1600 clips in a severe wind scenario.
Case 1 (low wind, clip upt to 20)
Case 2 (extreme wind, clip upt to 1500)
Case 3 (moderate wind, clip up to 100)
I would like to think that the copter is able to handle those situations in spite of the vibration levels (in fact it did, it completed the mission the three times with no problem). But this is something that I would like to confirm with expert voices. Do you think that it is safe to keep flying like this, knowing that sometimes when there is wind I can get up to 1600 clips 0?
I have EK2_IMU_MASK set to 7 following an advice from this forum, thinking that if something bad happen with IMU1 and IMU2 due to the vibration, IMU3 would come to the rescue. Is that…. let say… true? Can I sleep well with the previous statement?
I appreciate your inputs…
