That is just cool! I haven't gotten past my lowly Goldberg Eagle 2 Trainer. 
That's a good trainer. Back in my days as Club Instructor, the Eagle 2 was the kit that I always recommended folks wanting to get into the hobby go with. I've taught a lot of folks to fly R/C on Eagle 2s.
Now days I don't do much training, simply don't have as much time anymore, but when someone asks I usually recommend the Sig Kadet LT40 as a good choice for a first kit.
As for the Eagle (or any trainer) being lowly, consider this... I've been flying R/C since about 1986, and I still keep a trainer in my stable of planes, simply because it is so easy to fly and virtually impossible to lose control of. Flying the trainer is stress free, whereas sometimes it is a little stressful to take one of the scratch built planes that I have poured so much time effort and energy into to the field. It's nice to have a plane to fly that is a little more low key.
Something else I would suggest is fun, once you are a little more advanced then trainers... Buy a wing kit for your Eagle 2, build the wing with no dihedral. Then stiffen up the front end of your fuselage and drop a bigger engine into it. You'd be amazed by what fun you can have with a trainer hopped up with a flat wing and silly amounts of thrust!
