I use the HPI savage bag with some card boxes inside
Hard to explain how it all fits inside
3 large card boxes.
1 for electronics, psu, chargers etc
1 for tools, in smaller edit boxes
And 1 for spares, lots of spares!
Also in the bag I squeeze solder station, radio, 2 kit boxes filled with note books. Decals etc
I like the savage bag as it's big enough for most stuff but light enough to take abroad to race, bare in mind if you have to fly then you can have low weight limits,
