Chris,
Welcome to R/C, I know your going to enjoy it! Be sure to find yourself a good instructor R/C is far different than U-Control. The instructor will show you the ropes, it will be less expensive and will shorten your learning curve.
Nice airplanes! Its been a good while since I've flown U-Control. Did find an old Flight Streak up in the shed left over from years ago that looks like it needs to be flown.
Its great your son is interested!!!!! We've got some great young fliers in our club, some flying competition in IMAC. Younger fliers learn fast, great reactions, maybe its the video games. Its often hard holding them back a bit to get more experience before moving ahead very quickly.
Enjoy
