Far from stable

[snoller]

Hi guys,
i am really stuck and need your support...
I am using Flyduino Micro as FC and MW 2.32. I did get the copter in the air for a few seconds (see video here https://www.youtube.com/watch?v=hCpOftfU2bI), but the problem is that i cannot get it stable by any means, although i played around with PID options a lot. Everything is calibrated so far (especially ESCs and ACC), but when i try to get the drone up in the air motors are spinning at different speeds and it doesn't seem to level enough, even with very high PID settings for Roll and Pitch. When i hold the copter in my hand and move it into one direction motors are reacting accordingly in general, but also quite unbalanced.
Another observation, don't know whether it plays a role: i am arming through aux1 because the "normal" arming via throttle never works...
Any ideas what might be wrong?
Thanks in advance,
Stephan

Did you setup the transmitter so that in MultiWiiconfig.exe the sticks are at 1500 when centered and the End Points are 1000 to 2000?
This is the very first step and must be correct. This will also fix the ARM with Throttle/YAW issue.
Here is a good starting out tutorial for MultiWii:

Unfortunately yes - Values are below 1050 in low position. I also played around with trimming the transmitter which helped a little but did not seem to resolve the problem. When i start the copter for instance one side is lifting up and he will turn upside down - shouldn't the other motors immediately turn up and try to compensate?

There's. Lot of spinning going on there too.
I found that mine would to that when my motors weren't properly square to the frame, particularly the motor mounts used to rotate on the CF tubes of my talon frame.
That's now nicely fixed and my yaw is all under control.
