There is evidence that the Anafi will still fly on a single blade. However you are correct that the vibration would be extreme - both props would be thrown eventually, in let's say... 9 secondsA motor with a single blade would be so unbalanced it would shake itself to death instantly and either break the other blade or close/break the arm.
it is curious that two Anafi were found with their back legs closed after losing their propellers.
I like your style with the video presentationThank to help to resolve the problem of stall, so, propellers or software problem?
Here is the following part of my investigations.
I will submit for a return for exchange and see what happend.
Let me know if I am wrong with my deductions. Tx
