Interesting. Looks like it needs to be sitting on its own supports when on the ground - too heavy to be carried by the pilot/user. Therefore not in the "foot launched" category. Can't count as a single seat deregulated microlight (or any microlight for that matter) because it has no wings and therefore wouldn't fulfil the wing loading criteria. So its going to be subject to usual airworthiness requirements. And we know what that means...
