You won't need the 2nd one. If you crash and damage it you can just buy balsa sticks or sheets from a hobby shop or online and cut your own pieces with a much lower cost.
For glue on your first build I would NOT recommend CA type adhesive, it dries way too fast and is unforgiving. Go to the hardware store or WalMart and get a small bottle of Titebond II. It can be cleaned up with water and dries slow enough to give you time to adjust parts as needed. You'll also want a 2' x 4' ceiling tile (the kind used in drop ceilings of office buildings, available at places like Home Depot, or maybe even ACE Hardware) and pins to assemble the pieces on. For pins, a "T" style would work well, although regular pins can be used if needed. They're not as easy to insert or remove, but if you want to keep costs down they'll work. A roll of wax paper, Saran Wrap, or parchment paper should be used between the plans and the balsa so you don't glue the wood directly to the plans. If your parents cook at home regularly you probably already have this. To cut all the "sticks" for the fuselage and wing spars a razor saw is a huge help. Maybe $5 from a hardware store, although the better ones like I mentioned a few days ago are around $25, but they are much handier at cutting accurate angles. Get a small package (or single sheet if the store sells it that way) of sandpaper in 220 grit and 80 grit, preferably with an adhesive back. From the paint department ask for a paint stir stick (normally FREE), which you will stick the sandpaper to, making a sanding block. Don't just use sandpaper in your hand, the results will be uneven. I'll also recommend a couple small, cheap paintbrushes to be used for the glue. Instead of squeezing glue onto the wood, put a little bit on a paper plate or something disposable and use the brush to apply it only where you want it. It's easy to over-do it, so watch for extra squeezing out of the joint and use the brush to clean it up. Too much glue is NOT your friend, it drips down and creates blobs which are hard to sand. All this stuff combined might run $40. Less if you don't need to buy the brush or wax paper. I've been using the same brush for 2+ years, and am careful to always clean it after use.
