Designed for the special needs of the gasoline-powered flyer, the Gas Passer Flight Box features an extra large compartment to hold a 1 gallon bottle (3.8 l), can or DuBro's EZ Fill container. And it wouldn't be a SIG flight box without roomy parts drawers and a large battery compartment for wet or gel cell batteries. Builds fast with 100% laser cut parts and easy-to-follow instructions. Finish it off any way you want, or just coat it with good polyurethane for a polished, professional look. Power panel not included.
