I heard a long time ago they were advertising themselves as LSA and got taken to the ringer by CASA because the Subaru engine doesn't meet the ASTM standards, and the aircraft is not built by a company that could ever comply with the LSA requirements (ASTM standards) for engineering or production (so I was told during and RA-Aus meet the people event).
There was one at our airfield for many years and it was out of the sky for a long time getting converted from factory built registration (for which it never ever complied, but was registered by the RA-Aus by mistake) and then it went to the 19 category which is amateur built, non-factory built or certified. The Subaru engine was far from reliable and gave the owner so much trouble that he eventually sold everything for about 20 grand and gave up flying forever.
The new owner that purchased it was from Perth and he got as far as Goondiwindi before the engine destroyed itself for about the 4th time and the last I heard it had been tied down there and abandoned with the new owner deciding the aircraft was not going to do what he wanted so he caught the bus to Brisbane and flew back to Perth and then took legal action against the owner.
I was never told the outcome. The best thing to do in my opinion would be to contact the RA-Aus technical people and ask them about the aircraft, problems, reliability, how many were made, how many hours flown and from there you can make an informed and considered decision. It might take a week or 2 but they said that they had access to all of this information at the latest meet and greet.
