If I remember correctly, Evans aircraft had them on their website as a
free download because he didn't want the resposibility of someone
paying money just to find out that it didn't really fly. Later he took
them off all together because of the liability. If the designer wasn't
sure if it's airworthy, why would you? On the other hand I have emailed
a couple of people who have built and flown their own.

People who have built them tend to say performance is adequate for a
single
person but marginal for two normal size persons.
