Probably more people have noted the length of the list of problems you've had that would have been fixed almost immediately if you had found an experienced flyer to check over your airplane.

I would hazard a guess that every experienced flyer who has helped in this thread feels a bit of anguish. They know just how many problems you haven't found and that probably won't show up until that plane leaves the ground. It hurts a lot of us to help someone get to the point where the next problem will most probably kill the plane.

The plane won't taxi straight? That's just a guidance problem. The rudder isn't the only thing that guides the plane. Good thing however, is that ground guidance usually isn't instantly fatal.

Don't sweat people losing interest in the topic. It's human nature. Some people are just like that.

Good luck.
