RE: Why wont my Kaos spin right
Pushrods will bend when pushed, if they aren't sufficiently stiff and/or supported. They can pull without a problem even when insufficiently stiff or supported. So SOMETIMES, a surface will be insufficiently effective one direction, while work the other direction.
There are often many possible reasons for a problem, and the reasons don't have to be directly associated with the problem. For example, this problem would seem to be an aero one, but could be a mechanical one.
