UWS truck box.
It just barely fits too, but it's the easiest way to bring it to the track, hobby shop, etc... without having it roll around in the bed of the truck. Plus there's space for a few gallons of fuel, the radio, batteries, charger, an LST
and some tools. If I were to carry it around though, I'd just go the duffle bag route. It's hard holding the truck, radio, glow starter and spin-start at the same time. Plus the weak bumpers of the LST means I can't hold it with a single hand without the bumper bending which I don't like.
