New from the folks at JConcepts is this Breathable Mesh Chassis Cover
for the Traxxas Slash 4×4 LCG. The simple to install cover protects the
chassis from debris while still allowing airflow to the electronics,
unlike some over-trays that can cause heat issues. The cover attaches to
the sides of the chassis with hook-and-loop fasteners and includes a
zipper in the center that allows for simple battery changes and routine
maintenance.
