Copter 3.4 dev: Y6B YAW problem. Yawing left - goes down and another way around #4652

Issue details

Hi guys!

Have built Y6 1.3m on Navio2 and RPi3, ArduCopter 3.4-dev. In stabilize mode it flies more then awesome in any direction except yaw control. When I push yaw left - drone turns and goes down a bit. When yaw right - goes up.

In AltHold mode the drone tries to stick the altitude but goes up-down at the same time while yawing. The same in Loiter, of course.

All the props are from one order 9" (35% hover throttle), all ESCs are well calibrated. No yaw mixing on the RC. Problem is still exists after motors moved twice close to the center.

Tried to tune PIDs for yaw, not precise, but it doesn't help a lot.

@amusinov, thanks for using ArduPilot. It's best to raise support issues in the forums here: http://discuss.ardupilot.org/c/arducopter/copter34 Please include a dataflash log as well. Really though, it's most likely just tuning. Have you tried during an autotune? You'll find some instructions on the wiki. http://ardupilot.org/copter/docs/autotune.html
