I haven't posted any model here for a long time so let me introduce you my latest alternative models built out of set 42060 - Roadwork Crew.
The first of them is Formula 1. It has pretty low functionality (just "hand of god" steering) but at least I've made something original. :-) Most of formula is only 3 studs high so it was big challenge to squeeze steering in it.
Another alternative model is Propeller plane. It whirls its propeller when you're moving it around. This model is literally full of "crazy" building techniques because I had to connect together all those liftarms going in different directions.
I've built both models for competition in building alternative models out of set 42060. If you wanna see what other competitors built, check this link:
