I purchased the 727 a few days ago. And I am very disappointed because the airplane is not flyable due to auto pilot and pitch trim issues.

First, the stabilizer trim is unrealistically sensitive. It's a pain to fly manually.

Second, the auto pilot pitch knob has no effect, i.e. it does not control the pitch at all.  I have to do it with the stabilizer trim, but then again it's way to sensitive. It's a real pain.

Third, the altitude hold function is an even bigger pain. At some point it does not hold altitude anymore and the airplane begins pitching up and down like crazy.

I get the impression that I just wasted money...
