Nothing lasts forever

And some things last for a very short time indeed.
Yesterday we had the maiden voyage of the ArchCopter v2 and we had a very good first flight, as illustrated below.

First stable flight. First flight ever actually.

It is very sensitive, the smallest amount of throttle will send it towards the heavens like from out of a cannon, making the landings a bit hard, but the new and improved landing gears (as seen below) seemed to handle it very well!
New, jointed landing gears.

But, all things eventually come to an end, and during the last flight, we lost one of the motors in mid-air (one of the ESC plugs vibrated loose), causing it to spin out of control. This caused the hexa to start spinning around it's own axis, which in itself is not a huge problem, but before we were able to bring it down safely a strong gust of wind caused it to go belly up 10m above the ground. After that, needless to say, all we could do was pray for the electronics to survive. Which it did. Phuh!
We also caught it on tape for your amusement, enjoy:

And then there was silence.

Today has been spent salvaging the parts that survived, which turned out to be surprisingly many! Erik has also mounted the magnetometers on a couple of PCB-boards and soldered on plugs, as such:
Very fancy electronics.

Albin has not been idle either, as we can see below:
