I also keep a short length of fuel tubing in your field box...Oh, did you order fuel tubing? Another thing is a small set of screwdrivers, straight and phillips. Glow plug wrench and for your "Deluxe" panel you will also need some extra banana connectors. Do you have a battery charger for the 12 volt battery, how about an inline filter for your main line to your engine from your fuel container, better if used as the clunk. You can purchase a "Prop Reamer" either standard or metric, most have 3 or 4 steps so one will make 3 or 4 different size holes. A small container of thin CA in your field box is always handy to have with you. I know guys that have tons of stuff with them including an inverter to run all of them
