ArduCopter Y6 YAW broblem #208

Closed GoogleCodeExporter closed 9 years ago

The problem is difficult to explain, because my language skills are weak.
APM 1.0.36 and 2.0.35 AC version of the software in use.

Frame version of the Y6 and x used. What is the correct X, + or V?

Yaw is right, as usual, but the left has a quick temper.
Engine revs do not go smoothly and will be prying the left.

An unbalanced Yaw is a hardware problem. Your ESCs may need recalibrating or 
your motors are somehow not straight.

The problem is not the esc, or calibration. The problem is software. Watch the 
video.

I think that is actually correct. The motors 2, 7, and 8 for a Y6 are scaled by 
.92 to deal with airflow effects. I'm not a Y6 pilot myself, this was just what 
I was told by a other users. 

So, when your turing right, 278 will go higher, but when you released the 
stick, the nav_yaw variable was set to goto the right. take the board and 
rotate it a few degrees. Does it return to normal? Do the same after a left yaw.

So what your seeing in the video is the .08 of the normal balance being matched 
with a similar command to turn left.
That's my theory!
