My question it do you really need a big starter box to take out to where you actually start you plane or do you just need something to carry your battery, starter, glow igniter/cable, and maybe a couple of tools? For major work, I have a three drawer plastic tool box that I tend to leave in the truck. I use a light weight table shown below, put my starter and battery on the bottom and start my model on top. This prevents the battery and starter from getting in the way. The other nice thing about the table is it only weighs in at 27lbs so it's not going to be an issue to carry it, especially when it's folded up
