I bring a tackle box (my flight box) with screwdrivers both slotted and phillips in #2 size and a set of precision. I carry two glow igniter's, one primary, one as a spare. I bring a glow wrench, spare glow plugs. I bring an assortment of props. I have a spare prop washer & nut as well as the thrust washer just in case.(I had a ruined fly day because of a backfire in flight that resulted in a missing spinner,prop, prop washer and thrust washer. that won't happen again!) I bring some thin CA, two sided tape, fuel tubing, a box of rubber bands. (I don't use them, but I've helped out a buddy a time of two) an assortment of clevises, wheel collars, set screws. a spare servo & servo arms. allen wrenches & a few spare 1.5mm allen wrenches because how easily they round off. I normally bring a gallon of fuel, even if I only plan on flying a few times. a fuel pump, my starter and on of those 12v automotive jump starter packs.(that will start my planes all day+ if I need to charge a battery I can use that instead of opening the hood of my truck. not to mention the times I've helped out someone who runs there battery dead) I bring a crescent wrench, pliers (needle nose and slip joint) zip ties and a pair of dikes.I also bring some glass cleaner and a roll of paper towels, and I always bring a hat, and a gallon of drinking water, a good lighter and a full pack of smokes.


P.S. the lighter and smokes are optional
