I built this box to save time setting up and packing up at the track.
Radio, charger, batteries, tools, spare parts, manuals fit inside the box. Vehicle is bungee'd to the top. Handles on the side of the box, so I can carry it easily.
So, when I get to the track, I:
1) Set it down
2) Remove truck from the top
3) Open it up
4) Plug it in
5) Go.
I need to figure out a good way to mount the charger - on an angled stand or something. Years ago, I had a power supply and a Competition Electronics charger mounted on the top shelf.
