I flew the 4 seater some time ago. The people were very friendly and full of plans to sell lots of aircraft and get serious production volume. The aircraft was restricted to two seats and had a lot of things which were to be changed in the production version.
I was helping to advise a friend who was interested in buying one. I advised him not to go for the aircraft until at least 50 were under construction and he could fly a “finished production” version and talk to a number of builders. The aircraft appears to have vanished since and the hype has moved to the M106 which I know nothing about but appears to be entering a very congested market sector.
