Assuming you are talking about hobby zone's firebird outlaw, or aerobird. The firebird should only cost you about $50.00 or so, RTF with everything included. The aerobird, about $120.00 or so. With 75 bucks he should be able to get the firebird, and an extra battery, shipping included if he buys it online.
I just got into rc flying, and I have a firebird. You will be able to fly it in the park, and it is definitly a lot of fun for a very first plane.

However, like the post above, once flying it, you will probably want to move onto something bigger and better pretty quick. Again, being on such a limited budget of only $75, it doesn't sound like thats possible. All I can say is you will definitly have fun with it. Just make sure you take it out on a nice calm day for the easiest flying.
