If you think you can keep going with this hobby without tinkering then you are in the wrong hobby. Things with moving parts will need maintaining from time to time and moving parts from China might need fettling out of the box. These issues are realities that won't be going away anytime soon.
Reading through your long post, I seems that your stiction issues were occurring when you tried to fly with the pressure of one finger? I just tried that with mine and, sure enough, there is a little bit of stiction there that I never noticed. I certainly don't notice it with one hand on the stick. Once I get my extension sorted even that minimal stiction will be gone.
Anyway, the glass is half full for me and I'm grateful we have access to affordable hardware like this. I'm certainly also grateful to the users who posted calm and sensible reviews laying out all the pros and cons, I'm just not overly interested in the whining.
