I made my own flight box 30 yrs ago and I am still using it .. It has a power panel but you really dont need one..The only thing I use mine for is hooking up my elect starter and I could do that with the clips that come with the starter...Keep your flight box as light as you can ..I have found that I can go to the thrift store and pick up something like a lunch kit or two and I will use it for putting some different glues and a bit of wood that I might need for emerg repairs..And in another box maybe some more tools that might come in handy.These can stay in your vechial untill you need them ...You will notice different things that you need as time goes on... You will need and elect starter , and a battery to power it ..A glow driver , 6 inch cresent wrench , needle nose pliers , a set each of standard and metric allen wrenches , A fuel jug with fittings and a fuel pump either elect or hand crank..,A spare glow plug or two also a spare prop , a glow plug wrench , the 4 way kind that fits your prop nut is good , a few screw drivers ..Saftey glasses . A hat with a brim..I carry a rag and some spray cleaner I make to clean my plane .
