Should have included a photo of the platform itself, it doesn't do the inverted thing (but I'm sorta glad about that, its hard enough as it is keeping stuff from flying about the pit when maneuvering)
Here's a link to the platform which the pit is sitting on. Its three feet high, which does place limits on how how the cabin can be on top of the platform.

I've had a couple of near misses with the ceiling inside the house... so its time to build a shed with plenty of head room ;)
If you ever really want to do the inverted flight thing head to the smithsonian in DC, this thing is a hoot, definitely not something you can fit in the average living room though......
