You have opened a pretty big box here. You will have many answers that will be just as good as others. So here's mine:
Avistar with an OS46fx (well now it is a 46AX) but they are the same. I really liked flying it and it will still be a blast to fly even after you move on to your second plane.

Let the floodgates open....

Basically, high wing, solid engine, dihedral in the wing, usually a trike landing gear, but a tail dragger will work just as well, and a good radio (I started with a 6 channel Jr662). By the way, I am not trying to sell you JR, OS, or anything in particular. I just know that the Avistar was a good beginner for me. And there are a lot of others on this site that will agree.
