This is my first YAK 54 in its 'planky' profile form which is the one that help me out sharpen some serious 3D and aerobatic skills to the next level. Its made from extremely durable and almost indestructible EPP foam which allows me to smash, wack and bash to the ground. Its also can easily be repaired with hot glue due to dense flexible material. Slightly heavy than standard profile 3D plane but large in size and have a huge power to weight thrust ratio to allow me to peform cool 3D and aerobatic tricks.
