I have been making preparations to buy an ARRMA Outcast 4S this summer. I've got a charger and will order batteries when I get the car. I also have a LiPo bag (don't want the house to burn down!). I'm thinking that the best way to transport the car and all my other supplies for it and any emergency repairs would be a rolling toolbox that I have. However, it's not padded. Is there some kind of foam insert I can get that I can arrange or shape to suit my needs?
