Another good option is to get a plane with everything you need. There are many planes out there that have a good beginning radio, servos engine and they usually even come with a simulator to get your feet wet before you take it outside. Of course now for the disclaimer before I get flamed. You should always (if you have the opportunity) have a qualified trainer show you the ropes at a designated airfield. Make sure you get AMA and be prepared for your knees to knock for a while.

Here are some options:

There is also a mustang and a raptor from Horizon but I have never flown them or seen them fly so if you go that road it will look good but training ability in my opinion is questionable.
