RE: brothers B-day present
There was a similar post by someone on a budget. Several of us suggested the Tower Trainer 40. They sell it normally for $69.99 or something like that, which is a deal.. it's a great trainer. That's the sale price, by the way. It will require a radio, servos, and an engine. The Tower 46 is right around $85.00.
If you think he will stick with the hobby, I would suggest you get a good 2.4 GHz radio system with multiple model memories. I own and use both the Spektrum DX6i and the DX7. Both are fine radios. I also recommend the Airtronics RDS8000 which is also 2.4 GHz and is reasonably priced.
You can get quality servos such as the Airtronics 94102Z for right around $10 each, and you will need four of them.
Glue, both epoxy and CA will cost you another about $20.00 (more likely less) and you will have a complete package and ready fly after maybe 10 hours or so of assembly time. You will need fuel and a glow igniter.. and he should be ready to fly.
If he has never flown, just about everyone on here will recommend that he work with an instructor at a local club. Most likely they will require AMA membership to cover insurance issues.
Another thought is to call or visit a local club and talk to someone there with experience and get some advice as to what the club is using with regard to radio systems. Don't fall for brand name issues that some will give you because all the major radio systems are pretty much the same and are the very best quality. I only recommended what I use because that's what I use. Any system will work as long as what you get is compatible with what the instructors at the local club are using.. that seems to steer most people toward a radio system type. Get what works and what will help him learn to fly and you will be very happy with whatever you choose.
Best of luck.
