Problem: One motor is low rotates

[Bagroid]

Hello guys! 

I am new to this forum and new to quadrocopter flying as well.

I need help with building my first quadx copter with crius aiop v2 and multiwii installed on it.

So my problem is this:
As you can see on first picture, when I go full throtle on of the motors goes max to 1600 and after a while it continualy loses it rotates as low as to 1100 as you can see on second picture. The third picture is from sensor graph.

My copter was absolutely absolutely flat during the test. I have calibrated ESC, mag and acc.

Any ideas please?

I suppose the real test is to pick up your quadcopter and see how the motors react when you move the quad around. When I test the motors without props on the ground I get similar weird motor behavior. Not sure why that happens, but if your motors react correctly to level changes it should fly well :-)

I have the same problem. Board triggers low on arm 6. Did you solve or fly ?

My quad migrated two weeks ago.  I was telling it "bug", but I am wrong. It was a bird. Tried a few times to take off slowly, every time it fell to side.   So I push to full throttle and it took of.  I couldnt control it and it rise and rise. When I understood that I couldnt control it, I decided to crash land before it vanishes. I cut the throttle near the trees hoping to find. I searched for it 3 days in the woods. May be it found a bug/bird to breed. So it didnt come back. I am such a newbie that I didnt mounted buzzer which I own one. I think there are more to learn and experience.
