TIMMEEE. Whilst it may be fashionable to have a dig at the owner of that "chieftain with winglets and Q tip props" I think the answer may be more mundane. It was a Panther Navajo, very extensively modified and I think (but may be wrong) in the US Experimental Category. It may not be possible to register it in Australia as some of the mods did not have an STC, or if it were, the CASA BS factor would make Australian Registration a horrendous exercise.
