My newly finished Bill Hell flight box (no, Billy, I won't sue you if it blows up

)
Fuel and battery in bottom box, separated by hardboard panel. Fuel has a vent line that is cutoff when fill hose is stored (I can actually lie this box on its back without spillage). Master switch with homemade voltage meter (3 red LEDs), field battery charger and fuel switch make up the front (I'm still waiting for a prettier fuel pump switch).
I cut out tray for fuel jug, but after reinforcing with hardboard (painted to match), it's very sturdy.
I cut out the tray of the top box as well for radios, and will add padding soon (although the radios are nice and snug already).
