This is field box 3 for me. My first one was a wooden monster that held everything but weighed too much. My next one was a modified tool box but in my effort to lighten up I wound up having to carry the field box and a tool box.
I found the Black and Decker Master Cart at Home Depot for $29! CHEAP!
It is a rolling 2 part tool box. The lower section is perfect for fuel and batteries and also has plenty of room for props and a starter. The top of the toolbox comes off or stays on. It has all the compartments I need for the little stuff. It has a tray for my tools and is deep enough to carry my TX and Hitec field charger plus batteries. I carry so much because I fly at a sod farm in the middle of nowhere. If I don't have something my fly day is over. The pictures will show you what a great box this really is and the kicker is that it fits in the trunk of my Caddy (roof down) with my Knife. HOW MUCH MORE COULD I ASK FOR?!!!!
