Flying brick. Those planes have been sold out at Raidentech and Nitroplanes for a long time.

Here is some helpful advice. Learn to fly 3D using a lightweight plane. Look for a large thick wing and a large wing surface to weight ratio.

Profiles are not the prettiest, but they are good at 3d training. They are more stable in almost all manuvers because of the low wing loading. You can overpower them so that you have more than 2 / 1 power ratio.
