Often after a crash, the drone will find itself on the ground upside down. From there, assuming the battery is still intact, it would try to right itself, meaning the props would spin crazily at high speed and continue spinning while on the ground. They won't stop until you it runs out of battery or you find it, turn it right side up, and use the controller to stop the motors. So it's clear what happened is your motor mount broke or bent during the crash causing a tilted motor and so the props shaved away at the top of the drone. Another possibility is the motor overheated while spinning and so the plastic motor mounts melted and loosened causing the same thing. The latter has happened to me personally once after I crashed in the woods.
I think the last sentence in post #8 is the best guess as to why you crashed - motor or ESC. It seems unlikely a prop flew off if you found all four props near the crash site. I would guess motor has a better chance of failure than an ESC during a free flight. ESCs really don't fail during flight - they fail from the motor being locked up after a crash. It's possible a tiny piece of gravel was in one of the motors causing it to lock up or become intermittent during flight.
By all accounts, the drone stopped moving once it hit the ground. So if it's true that the hole on the right was caused by the propeller hitting it continually, it happened in the air. Maybe after something hit it? Might be. But the CCW motion the drone showed over a minute before it fell tells me whatever failed, failed gradually... |
