RE: Field Supplies
My brother and I travel to the field together, and it's about 45 miles each way. There are no hobby shops near the airfield so we take enough stuff to do fairly minor repairs. We have a tool box and tackle box that stay in the truck most of the time.
We have a small box that has the essentials for getting the planes fueled, started, and tuned: Fuel, fuel pump, glow driver, starter, tach, screwdriver.
