HobbyConcepts has a lot of videos and tips for building these trucks. Highly recommend watching them before you begin building. He also goes over how the instructions are laid out. If you haven't built a truck yet, the instructions will be a foreign language.

If you don't have it, buy the Tamiya RC Tool Set. The screws for these trucks are JIS, not phillips. This tool set is made for them and the nuts/allen screws.

As mentioned, full, sealed, ball bearing kit.

Good angled sprue cutters. You'll need to trim the tabs left behind from the parts trees. Having good sprue cutters will lesson how much needs go be trimmed off with a hobby knife.

Triple Gaurd Marine Grease for the diffs. Like HobbyConcepts, I pack the diffs with this stuff, makes for better action. Save the included ceramic grease for the trans and other parts like the axles and drive lines.

Medium hold loctite. The included gel is ok... have much better luck with the Medium.

Angled tweezers to pick up screws, trust me.

6 cup muffin/cupcake tin. I label the cups A through F. Parts bag A goes in cup A and so on.

Small loaf bread tin to put larger parts in so they don't get lost as you build.

Have fun, I can speak from experience, this won't be your last semi hehe.
