The Llwyngwril Systems' Tumbler was an almost perfect solution to back-flips, front-flips and staircases (take note Daleks!). Sadly it was still not proof against angry aliens from Pluto trying to push you over sideways.
++++++++++++++++++++++++
I've checked and there's enough clearance for the central part to spin all around. It'll be interesting to build a real one and see how it rolls down a staircase!
