Original, and reproduction parts here, for the Raptor.
They also sell the Klone 50. To mix, and match from other helicopters its best to ask about a single part. To many posibilities, some may need other parts to go along with it.
Not sure what a Hobbyking 50 is. They sell an Aeolus, and a JZ. Very different than the Raptors, so entire assemblies would have to be used.
