The servo arms ARE repositionable if you can reach the screw. To reach the screw you may have to pull the entire servo from the frame, which can be difficult because the double sticky tape holds it really good. It is then very easy to reattach the servo to the frame, again with double sticky tape. But the whole proceedure of removal and reattachment takes time and patience.
I have to admit at first I was a bit intimidated by the seeming complexity of this helicopter, but now that I've changed many of the parts it seems hardly more than a toy.

True, there probably is no real benefit in having all the servo arms absolutely level. But it does look nicer! I'm currently doing an entire frame replacement and decided to go through the entire process of checking out each and every part/assembly. I didn't break my frame in a crash, but I didn't like the condition it was in when it came out of the box RTF (brand new) Like the old saying "If you want anything done right you have to do it yourself". When my LHS gets some of the aluminum swash plates I'm going to install one of them also.
Anyway, I get personal satisfaction from a job well done, plus there is the added benefit of having gained experience setting up and adjusting this helicopter. That is why I'm going to do the DD tail replacement. Just so I can experience it for myself. If I don'tlike it, I'll convert it back to original.
