Sorry to divert from the second reply, but I am slightly alarmed at your "deadly 180 out of cloud". What is so deadly about it? The one time I saw a massive wall of sea fog coming straight at me (flying EBKT-EBFN at the time) I did make a 180° turn, but slowly and staying well clear of the stuff; and no harm came of it.
As to the subject of your post I have little to say, being a low-time microlight flier. Can only say it took me substantially more than 15 hours before solo, but that must have been due to my lack of youth and mental adaptability, added to several changes of plane, instructor, and environment.
I second Backpacker's remarks about the various engine technologies and how to handle them. Might be hard to find an instructor with experience/authority on all sorts, though.
Unusual attitudes came at a very early stage for me, even before first solo. Was limited to a straight ahead stall, though, spins being forbidden for microlights. After first solo I got sideslips, and when I mastered those, powerless landings. Powerless landings had to be sufficiently OK before I was released on solo cross-country.
