HPI RS4 Sport Lipo Holder and Belt Support
thingiverse
This is a remix of a Lipo Holder for an HPI RS4 Sport (a vintage 1st Gen version). This has been modified to add a small pulley to slightly raise the belt off of the LiPo case. Otherwise they would lightly rub so this hopefully prevents belt wear. Its not enough to excessively tension the belt. Just lifts it up by about 1mm. I also modified the holes for the battery retention to utilize retention posts from a Traxxas Rustler. Required additional parts: Traxxas 3727 Battery Hold Down Plate (You used the printed bar with these metal posts. Two F684ZZ Double Shielded Miniature Ball Bearings A M4x20 screw with a M4 washer and Nylock Nut. Do not overtighten. Just tight enough that the screw is fully in the nylock nut but the bearings spin freely. Easier to assemble outside the car first. This has been tested to fit a Gens ace 2S 7.4V 5000mAh 50C LiPo Battery HardCase measuring 46.5mm wide, 138.5mm long and 25mm high.
