I can only say from pics that they are two different helis that have parts in common, kind of like the Trex 450 and the Black Hawk 450 have parts in common. The head assembly looks different, and the HBcp2 has a belt driven tail where the Blade cp has a motor driven tail. It's not like the case of the Walkera 22e, the Eagle Exceed 50, and the Venom Night Ranger 3d, where they are all the same heli under different names. Maybe someone else can actually give you a compatible parts list. As far as your signature goes, I TOTALLY AGREE!!!!!! [sm=redface.gif](Angelic choir) 4:20 is the best time in the world!!!
