Hate to break the news, but to really make a go of the sport you should buy at least a 4 channel radio (a modest 6 channel computer radio would be better), a .40-.45 engine, and one of the trainers on the list. With a can of fuel and pump, a spare prop or two, you are ready to go. Expect to do this for $300-$350. Club membership and AMA will usually add another $100.

Anything less is too toy-like if you are really serious.

Or just go to the local club and talk to the guys. Poor college students usually can get some stick time on a club airplane. Often used trainers with radio and engines can be found for not too much money.

Study hard. Military aviation has their pick of the best and they really like engineers and science majors.
