Motors dont spin

My measurements with thread and ruler was hard to explaining for my wife

[brat002]

It is result of "near by default" PIDs configuration https://plus.google.com/115088185602590 ... 58CmsCqqrT
I afraid try with unconfigured controller again.

If your measurements are correct the mixer is as below:

I would not say 'it's near by default', but from my personal experience I can say that a QUAD-X can do.

It was not success story.
I started to tuning PIDS from P=40 to p=95, i from 0.0005 to 0.0009. Then was soft crash. I decreased pids to 85, but props was slightly damaged. Takeoff, then switch to pos. hold and quadcopter started rotating over YAW. Next was flip of death. Long range reciever and battery are damaged
Here is my mixing table and current PIDS. Could you look for my PIDS? PID values is in normal range?

Many thank for your help guys!

I think this mixing matrix is incorrect. Quadcopter wants to flip to back when throttle is up. Today I will try mixing matrix from multiwii.

check motors outs
If quad want to flip it's more possible.

It's definitely not the motor mix causing your problem. Like bluuu said, most likely you have a prop or motor mounted/spinning in the wrong direction and/or the motors aren't plugged into the right ports on AQ. This is a very common mistake and is easy to make. No amount of PID tuning will fix it. Go back to defaults!

As for the actual motor mix, no, really... start with a Quad X mix. The one Joerg posted doesn't really make a lot of sense... there's no good reason to lower the Throttle numbers at all. Maybe the yaw numbers are OK, but I would play with that LATER after everything else is working properly.

And yes, please, it's much easier to review your settings if you just save them to a file.
