"All you really need to get started is the kit, CA glue or white glue, 30-min epoxy, a hobby knife, maybe a hobby saw, T-pins, sandpaper and some small clamps or clothes pins. You can get a long way into the build, and then decide what you really need."
Based on the info at SIG's site:

all you will need are the few items listed above, some fuel line, and some covering.
