Re: Put a bounty on all drones
I'm tempted to downvote because you missed. But I'm not that cruel.
Though I did upvote the commenter saying it is a tall story, I can imagine at least one way to get a normal quad to drop a stone. Balance it on top, and do an automatic flip above something.
Here is hoping you get it sorted. I suggest a video camera to record the incident. The rest I'll not suggest.
