First time posting. Getting back into the hobby. Recently acquired a walkera genius fp from a family member that has never flown. They received it missing the ball link and upper ball on the rotor. I found the ball linkages. I'm having a hard time finding the the ball that screws into the head. Ordered an eachine out of frustration.. would like to get this up and running. Thanks for any insight, I'd hate to throw away the heli.
