Alternate for 5765 Transport truck Lego Creator Set. I wanted to try to build a lego helicopter in a long time and this set seemed perfect for it. The hardest part to build was the cockpit because there's few transparent bricks in this set and aside from the cheese slope, there's nothing in it to make an aerodynamical cockpit.
Nice helicopter! You did a good job with the front and window. Regarding your question on the buggy, it is pretty sturdy, but not like original LEGO models. I guess it depends on the kid; the model is playable but not suitable for rough play.
