Dunes Breaker

I build a lot of vehicles for space exploration. And in my imagination, i arrive on a desert planet. Sand dunes are everywhere.

How to get a small ship to move fast on sand terrain ?

First, a caterpillar ! But i don't want my model look like snow-bike.

So my idea was to build my model around a triangular caterpillar, with ski behind for direction.

This triangular caterpillar look so easy. But to get a small triangular shape that exactly matches the caterpillar ... And i absolutely want used wheel and not gear for caterpillar, this solution gives functional caterpillar on any surface, even on glass. (else, it's too easy)

I do many tests.

After that, the rear ski. To get the most realistic model, this ski most be fully mobile, up/down and right/left. So when you drive and turn, the ski is moving.

I also do many tests.

When mechanical is ready, some design :

And it's ready ! Let's go explore this desert planet !

Small model, but long build/rebuild time. I hope you will like it.
