RC Maker T4 & BD9 ceramic/ABEC7 bearing sets
RC Maker have introduced their new ceramic and ABEC7 steel ball bearing sets for the Xray T4 and Yokomo BD9 touring cars. Using ceramic ball races for the drivetrain and ABEC7 steel bearings for the hubs gives the best balance of longevity and performance. The ABEC7 bearings have extremely tight tolerances and prevent developing slop and notchiness, ensuring a smooth and efficient drivetrain for a very long time. The T4 and BD9 sets are available from now on.
