Mike, it’s a relatively easy kit to build, but some of the parts need filing and sanding. The tank is fairly straight-forward, but the cab parts require a little patience, and some fussy filing and sanding. I also recommend some good clamps and rubber bands, and weights to hold assemblies together while gluing. I tend to paint sub assemblies while building.
The older kits don’t include window glazing, but newer ones will say so on the box. The windshield is tricky to glue in, so some paint may need to be removed to glue them in. I recommend a liquid plastic like Tenax, or ACC.
