3D printed Yokomo YZ-870c saddle pack LiPo holder set. The posts are modelled on the original Yokomo design and fit to the car using the original mounting screws along with the original retaining straps.

The mount for the 4-cell side has a groove in the underside to clear the chassis backbone if fitted. Due to the rectangular profile of LiPos compared to the NiCads the chassis was designed for, the cell can only be mounted in the forward position as the layshaft would interfere with the cell in the rear position.
