Just re-read from start to finish, and I will probably keep doing that to keep all the good info fresh in my mind!
A little more info on my kids regarding attention span etc so you can tailor new stuff to that.
While I had them up, they traded off during the same flight. This was in part because they are just that close, and like to share EVERYTHING. (Weird I know, but hey Im not complaining!) The second reason, at least in later flights, (They flew a portion of three flights Sunday) was obvious loosing attention span. My son, as I said, got frustrated because I wouldnt let him fly beyond his capability. My daughter would stop "Because my eyes are tired" I think truly she just wanted to go sit with her big brother, and try to cheer him up.
So, my game plan for next time is this: 1st flight for BOTH of them will be teaching them a high altitude loop, and a full roll in a shallow climb. Then, each time they take over for there turn they will get a chance to play a bit before starting the work as Ken put it. Hopefully this progresses to full flight training sessions for each of them. Well my bird stays up for 15 minutes and has plenty of fuel to spare so 10 minutes of training time is probably the limit, it was for me when I was starting out and I'm an adult, (Read older kid with more expensive toys
