Hi there DIYers.
I have my first 3DR X8 with Pixhawk. Arrived 2 days ago. Beautiful condition, well packaged. Today I have been for 3 flights - all just hovers in stable (although I also briefly tested loiter).
In each flight, I noticed a sudden movement back right. On the 2nd and 3rd I noticed a preceding beep (short, sounded like an ESC startup) and on the 3rd flight I noticed the back right bottom motor stop spinning.
2 out of the 3 it gently hit the ground (no damage, just some small mud on the props) but only because I was close to the ground already. I strongly suspect the other motor would have compensated with height.
My gut feel is it is therefore an ESC or motor or wiring problem. But I was wondering what can be viewed from the logs? What are the best parameters to look for when trying to diagnose such as problem?
Should add, that when this did not happen it was super stable.
