I first saw one of those at the field when I was like 13 in the mid eighties, and decided to do anything necessary to scrape the $1000 or so up to get one going. Of course I dident even know how to fly very well yet

I remember drooling over the Byron catalog for hours. And that wonderfully complex sure- flow- Byron whatever fuel system.
And their fan system with " Unobstructed air flow"
Really high tech stuff....
