Absolutely Jim. Would like to see it. We'll figure out when and where we can meet up. May bring a couple other quad/tri friends too.

Sounds good! The more the merrier! I may bring a friend who is interested in building a scarab too.

Looked like the back motors stopped.
Connectors? wiring? low voltage?
Just guessing, there is no way to know by a watching a video clip.

I see that you have a serious vibration problem. Those vibrations MUST result in defects. All motors stop at the same time, this might move the problem to the commonly used components like power distribution or flight control. The beebs after the crash sounds like a normal initialization of the ESCs. So I assume, you have an interruption at your power distribution. Take care, that all of the connections are soldered perfect and try to avoid detachable connections wherever you can.

AND BALANCE YOUR MOTORS/ PROPS ;-)

I understand that could be a power outage the Esc?
very fine wires perhaps?

Do you have your esc set for nimh, not lipo? It could be a bad esc too. I had one do that on a 250. It shut down in mid-flight, but powered back up after it reset.
Let it idle on the ground for a while and see if any of the motors cut out, or if all of them cut out at once.

What was the pack voltage after the crash? I bet it was simply low voltage cutoff.

I saw someone posted this on a very 'intense' thread earlier this morning.
Came with a callout and everything...

Mine is flying so well in gyro, Imo if you just tweak with derivative from the default settings then it can help a lot. You don't really need to touch proportional unless it's under compensating and D is at zero.
Still trying to sort out level mode, I am really waiting for multiwii on android to be updated as it will make it much easier to sort it out. I think that I will just decrease derivative and it will improve it. The problem is that it remains level but quite unresponsive on the sticks.When I take off there is no drift but sometimes it randomly starts going to one side.

That looks to me like electrical interference to the camera, not vibration.

+1
It seems that the ESC's initialized.. you can clearly hear the 3 beeps that indicate a battery with 3 cells.

Once I had my easystar crashing because of a banana plug that was not good.. since then never used them again for battery plug
