Why in the H - E double toothpicks are they advertising it as a 3-D flyer?

"Designed by Will Hobby to be one of the best 3D fliers, Pole Cat embodies both speed and maneuverability. This is made possible by its lightweight material and high-quality construction. Its fiberglass fuselage and cowling made for ultra realistic look. The complete balsa wing offers high durability at lightweight. The plane is speedy and agile. It is one aircraft any dedicated 3D pilots cannot miss."
