I can not see what is unregisterable about it from the specs- taken from their site.
Assuming you build to suit our rules etc it should be fine or am I missing something.

*The standard engine mount is for the Rotax 503, 532, 582 engines.
Except the sound and lack of speed it is cool, and since it is alloy can be polished and painted for great drool appeal.
It appears to have a great view forward and to the sides and down for its type. And looks to have plenty of lift appears stable in the vids.
But more speed, retracts, higher g loads etc would be better.
But that may be possible with a few changes by the designer/builder in greece. It would have been designed for the euro 300kg rules but given it has a hp range up to 130hp stated he may have in mind a faster better suited to our rules version.
I saw something about retracts somewhere?
