Since I started flying EP and Gas in addition to glow,, the one box fits all stopped making sense, too big too heavy,
I have a fishing tackle box that holds tool, spare parts, screws etc, and a gun case for my TX, Charger and flight packs for the day,
Then depending if I'm flying gas or glow I just grab that bottle,, It all takes up a pretty small foot print and eis easy to transport up and down to the basement with the fuel staying in the garage,,

Started using the Tackle box for tool when I was racing cars/Trucks, a good complete too set is a must.
