When I got back into RC, I knew I needed a field box. I made one from scrap in the shop. Here is a picture as I laid out what to carry. This is an early picture. Now I added a cradle to hold the plane for set up. Not sure what it weighs now. Not too bad to carry. I have a plastic tool box for tools which I keep in my vehicle until needed. For the starter I used a regular starter battery. Then I made battery box for the starter. I don't have to carry the field box too far so that helps.
