This kit has opened up a whole new dimension to my Rokenbok world. Gone are the days of nintey degree angles. You can make your own elevator, taking your builds to new hieghts.
I've even made a trailer to tow behind my monorail, that can be outfitted in any number of ways to carry parts aound my builds. The angle blocks let you build bridges, that look real, and are strong enough to support multiple vehicles without collapsing. This is a great kit that can really take your imagination up a notch.
