According to its creator/aeronaut, the Fatboi is a bad boy when it comes to handling crash landings and tree collisions.
2x Balsa Airplane: The Fatboi (No.2)
The Fatboi No. 2 is the strong, robust cousin of our No. 1 Glider. The Fatboi can make all the same loops and turns as our No. 1 Glider, and although he is not quite as fast he will handle more crash landings and tree collisions!! The Fatboi is made completely from 2mm thick balsa wood.
