Helis are hard the only small inexspensive one I reccomend it the e-flight Blade CX coaxial rotor set up.
With cars and planes it is the same thing the better the radio the more costly it is If you like cars you are defenatly going to get hooked on planes For a If you go electric a slow stick or e-starter from gws are good choices If you go with glow a sig lt-40 Is the best trainer for the price. The most important thing is to find some one to help you learn how to fly Otherwise it can be an exspensive and frustrating learning exspeiance Planes dont have brakes or reverse
Good luck
