That $25 J3 Cub Flatout will require 3 micro servos, an electronic speed controller (ESC), a micro receiver, and a LiPo battery with compatible LiPo charger to get airborne. This assumes you have a suitable 72Mhz or 2.4Ghz hobby-quality radio already.

The electronics for flat foamy (Flatout-type) aircraft aren't cheap. The good news is they are reusable if you pile in the airplane, you simply move the electronics to another $25 airframe once your foamy is no longer repairable. You can usually crash a flat foamy a number of times before repairing it is no longer practical.

The particular model that you're looking at by Great Planes is designed specifically for indoor flying. The included 180-sized, brushed motor won't provide enough power to counter anything above the slightest of breezes; you'll need almost perfectly calm conditions to fly it outside.

Also, if you're planning on practicing touch-and-goes with this model, you're going to be disappointed. The landing gear provided are for "static display purposes only" and the plane is not flown with the landing attached.

If you're looking for a nice slow-flying indoor electric, this could be a fun choice. You'll need to budget $150 to $200 for all of the electronics you'll need to actually operate the J3 Flatout, probably closer to $250 if you need to purchase a full radio system and not just a flight pack.

Edit: Oops, forgot the aerobatics question. This particular design uses an undercambered airfoil design, which is great for slow indoor flight. It will make it difficult to do rolls with this plane and the plane will be all but impossible for a new pilot to fly inverted given the included power system.
