That looks great! I'm glad to hear about kids getting into the hobby and not just with an ARF or a styrofoam plane. Plus its a great hobby to get into at that age!
I started with Guillows models in grade school and built a 60" Clancy Lazy Bee when I was in 6th grade (not sure on how old that'd make me). I built and covered it myself, my dad had to help straighten out the fuse
