Just remembered the possible event.
Was lawnmowering around last week in sport mode going full throttle at 2–5 feet AGL. Total, massive blast. Flying with the MC, tearing around bushes and in between them and then... crash! My first and only.
Threw the battery, took 10 minutes to find it after I found the FPV.
No damage, been flying since a lot, no issues.
What happened? An especially tall, thick grass stalk wrapped one of the motor spindles, with the effect you would expect. As the aircraft tumbled in the grass and dirt, I expect the tips got bent as the prop spun sideways into the ground.
Was recording at the time, I'll try to find it.
