The Hitec Laser 4 radio system can be hooked up with a usb cable to fly flight sims. It can also be connected to a buddy box.

If you're interested in a more "capable" (more aerobatic?) trainer, the Mustang PTS and the Arrow .40 by Hangar 9 are excellent choices. So is the Avistar trainer by Hobbico. These planes offer semisymmetrical airfoils on the wings instead of a flat-bottomed wing. Flat bottomed wings are very stable, but they can't fly inverted very well.

Another inexpensive airframe that you might consider is the World Models Sky Raider Mach I:

This inexpensive high-wing plane should be very capable of performing loops, rolls, Cuban eights, Split S turns, hammerheads, and the rest of the Sportsman level pattern manuvers for aerobatics. At $69, it's a great value.

Edit:

For a more aerobatic aircraft, you might want to consider spending a few extra dollars and going with a Super Tigre .45 ABC motor or a Kangke USA SK .50 motor:

The extra power will come in handy once you move past basic training and begin performing entry level aerobatics.
