Sounds like you are well on your way. I've never tried the 17x6. I may need to. Flying the profile in close and low with the 16x6 can get old. The sound is a high pitched buzz.
"with a kid on the way" QuiQue and Chip Hyde both started flying at 5 years old. Just sayin :-) :-)

Just curios if you are going to run one battery or two? I run two in most of mine but on the profile I run one 3200mAh LiFe. It has two servo lead ends and a deans plug. I just run two switches and plug a servo lead into each one. Profiles are really tight on room and I wanted to save weight. I'll link it below if interested.
