Hot Racing Traxxas Maxx Tall Battery Hold-Downs (Blue)

Good idea and definitely a good upgrade, but like a lot of Hot Racing products, the machining is left....somewhat undone. The parts install just fine, but the inside edges of the slots where the velcro strap passes through are left unchamfered and sharp. During some hard bashing, this can cause those sharp edges to shear the velcro strap (ask me how I know), which leads to your battery being ejected. My recommendation is to get a detail file and put a good rounded edge on the velcro slots and it should work well.
