A lot of those kits used to be the kind of kits to start building on. and I've recommended them many times over the years. But I have a new standard that I recommend for anybody, no matter what age, to use as their first kit to build.
This plane is a great trainer to learn to fly on, but that's not what it was intended for. The guys at Balsa USA designed this kit as a first kit for somebody that wants to learn to build. And the kit shows it in everything in the box. The manual is 4 volumes alone. They literally take the builder by the hand and show them how to do everything. they start out with things as simple as how to cut the wood, how to measure, how to glue, how to cover, and so on and so forth. Trust me when I say this, you WILL learn how to build from this kit. The guys at BUSA put a lot of time and effort into designing this kit so that people could learn to build with it.
I'm working on a review of this kit. Heck, I've learned a couple of new tricks from this kit that I didn't know before. I highly recommend it.
And the neat thing about this is that when you are finished you have a great flying trainer for your efforts!!!
Hope this helps
