I was a friend of "Bolly" (Les) back in those days when he made props. (In Adelaide South Australia.)
He used me to test some of his stunt props on my plane. He originally started the business in the real early '80s making team race props and in Jan 1982 he made his first stunt prop. (10.25 x 6.25 two blade.)
The next stunt prop was made in March 1983 and it was a 12 x 6 two blade. He then went on to make numerous props as you know.
HOWEVER, he made a big mistake; He trusted some guys from Queensland to join him in his business and somehow they ripped him off and sent him bankrupt! (They wanted the ultralight prop side of the business all along.) He had to turn the ultralight prop manufacturing side of the business over to them. This was years ago so I don't know what he is doing now.
(Lesson; Don't trust anybody to join you in a successful business!)
Disclaimer: Of course this is only my honest opinion!
