OfficinaRC X4 brass 6mm pivot balls

From OfficinaRC for the Xray X4, these brass 6mm pivot balls are made in Italy with the best machinery and by expert craftsmen with many years of experience. The brass used, thanks to its characteristics, guarantees maximum sliding by minimising the friction of the pivot ball in the arm. The weight is very similar to that of the original versions.
