Then it dropped to the ground.

First I thought there was a short at some servo-leads. But boy was I wrong. It was the servo itself. One servo PCB got so red glowing hot, that it melted a hole into the plastic encasing...WOW...
Anyone of you ever experienced this?
The funny thing is, that 'til the end the servo was still working...LOL
I have never burn one, but I did have several seize up soon after I got the Mini.
I took on apart and found a little piece of foreign material that fell out. I put it back together and it worked just fine. Maybe that's what caused your problem.
