RE: Why wont my Kaos spin right
Aparently you have checked most of the obvious isssues, have you checked your aileron travel on each side and the stops?
Not having flown a Kaos, or even seen one of late I am not sure how they are set up but that is one thing I would look at.
And it is normal given the rotation of the prop and engine torque that you will get better spin/turns to the left than the right.
Although not knowing you plane I can not say for certain what you are seeing is normal.
