The catch is that it's not A Trex 450 SE. It's a knockoff. The tip off is the 3DX. Also it is shipped in several boxes. An SE comes in a small metal case. If you are new to helis I HIGHLY recommend going to your local hobby shop & purchasing one from them. They will be there when you need help setting your heli up. If you must by from Ebay I had great results from a seller called Rc expert. Heliproz & Grand RC have some good deals on packages. Do yourself a favor & get Hitec 56 servos, a Futaba 401 gyro & I like the castle creations speed controllers.
