Issue with AC3.4-rc1

Hi,

Tested the Copter 3.4 RC1, and found an issue which never happened before with the 3.4 Dev.
-After takeoff with Copter, I had to apply full right yaw trim.
Without trimming it started slowly spinning around.

There must be an issue since AC 3.4-rc1.
I had to increase the Rate Yaw P to 1.2 (one point 2) and the D to 0.1
With Pixhawk and AC 3.3 Rate Yaw was: P=0.2, I=0.02, D=0.0

The PID’s for Rate Roll/Pitch are also much higher than the defaults.
P=0.35, I=0.1,D=0.01

With the defaults it was not to control. (Over 30 testflights)
Frame DJI F550 1.9 kg. with Pixracer.

Hi CommandAir,
We really need logs to work out what is happening.

Thanks,
Leonard
