A bunch of us have already given William advice on how to fix his issues on both this thread and the other one. The issues he's described are part of the routine learning curve for this sort of plane IMO, and the advice given so far should ultimately (with practice) be enough to overcome them.
At this point IMO he needs to decide if he's willing to invest the time to learn such a complicated tool, and if so go off and practice, practice, and practice some more. There is no free lunch, and talk can only get you so far.
