Hi,

I saw this video about the Dzhanibekov Effect (Intermediate Axis Theorem)

I wondered if Orbiter would reproduce this rather entertaining behaviour of a wingnut rotating in space, and of course it does - very well

Here's a simple .cfg, mesh and scenario of a wingnut with Prime Moments of Inertia 0.12 0.26 0.22, rotating in space with angular velocity 360deg/sec around Z axis and 0.1deg/sec around Y axis.
