jr,

You are welcome.

Glad you found the source of the rotor head, that should help some...

Hard to say why it was changed over...anyone's guess...but it sure is easier to find parts for the stock CPP head, that is for sure!

You may even want to consider changing it back to an Eflite head, for parts availability reasons...

Good luck, hope someone can i.d. the part number for you...

Glenn
