The Thunder 3D has been in the works for quite some time and Krill wanted to make sure that they brought something new and special for the new FAI category & F6A Artistic aerobatics. Thunder 3D is highly specialized and purposely build model for 3D flying. As you can see on the pictures, Krill has implemented many new ideas, including a new wing platform and airfoil.
Thunder 3D is NOT meant for beginners and/or learning 3D flying!! You should have at least some knowledge of 3D flying to fly this airplane. On the other hand it will surprise you by it's maneuverability and endless possibilities in 3D flying.
