I would add a metal tool box (for charging batteries in), lube (I use WD40), Ball Link pliers is a good investment ( I went thru 3 helis before buying one, sorry I didnt get sooner), also I would get a decent tackle box to put all your junk in. I found one at dicks sporting goods that was perfect, with compartment for up to 325mm blades and tons of convertable spaces for all the little parts and crash kits.
