Tower Hobbies.com has a great selection of electric planes, Hobby Lobby also has a great selection. All of these lectric planes and helis are a blast!!! I'm still learning the heli and still cna't hover it very well. Electric planes are easy to fly, and although many are some what underpowered you can upgrade without going the LI-PO route by putting in a slightly larger motor and making sure you are using micro servos, etc.
