It is a additional part we decided to add to certain kits post many unexpected occurrences. Those propellers which needed that "pyramid" part got them.

Again, a long story. I voted to have that part in every hub kit. I think it is a necessity. We sell them for about $20

If you still need help, please give us a call and I'll explain the progression in depth.
