I have 2 BIG field boxes that are really tackle boxes that has a compartment with plastic boxes with dividers that I keep mine in with the label off the packet so I can keep up with the HPI numbers. Right now as far as HPI not counting my others RC brands I have a Rush, MT 1 ¾, Savage and a Micro RS4. I all so have the original box my Savage 4.6SS kit came in FILLED with extra Savage parts not counting what I keep in my feild box. Right now I only have about 18 RC cars and trucks as I sold some.
