I second the Mid-Star 40. It's a very easy build and a nice flying plane.
Here is a good build list
1st a kit easy build boxy plane like the Mid-Star or the 4-Star.
2nd another kit of one with more curves like the Super Sportster
3rd Scratch build from plans! Get plans for another plane in the same class as your first two. Learn how to make a parts list, order wood, acquire hardware, engine/motor. Cut your kit. then assemble like the first two.
Do this and your will have the skills to build any of 1,000s of plans for RC planes rather than the 50 or so kits left on the market.
I would agree with this list but none of my building students ever tried to build from plans on there third plane. I have one that I know can do it but he really doesn't want to give it a try. It isn't all that hard to do, it's just cutting your own kit but you are building without the aid of instructions or photos. I like it myself and find it easy but I was building kits for a long time before I went to plans. I do wish all kit builders would give it a try though, it's very rewarding.
I used to use the Super Sportster as my building aid when teaching, it's a much better plane if someone is learning stunt flying. I can't even remember who turned me onto the 4* kit but it's an easier plane to teach building with. A student and I just finished another 60 size a couple of weeks ago. I showed him the SS ARF at the field last week and I think he may try one for his first all by himself build real soon.
