T-Motor MN2806 KV650 with Arducopter 4.2.x

Finally, autotune completed, THANK YOU so much to @xfacta . I like to know how and why you suggested/derived those PSC_XXX and ATC_xxx values.

Interesting, AutoTune allows higher ANGLE_P gains

@xfacta
These values should not be increased beyond what Autotune suggests without careful testing. In most cases pilots will want to reduce these values significantly.

May I know the reason to double it instead?
