I dont know, my stock SA couldnt even do a spin, without the plastic gear that runs the tail flying off. He must have gotten one built on a wendsday. Mine, I think was built on a Friday, at about 4:45pm. Quality was sub-par. To include my Align ESC that didnt work. Its all good now, have a beautiful CNC Diablo head and tail on her, and wow, NOW she seems like a fine little birdy.

Though, I do think I may be upgrading to a Diablo soon.
