is the 1.5 (or B series if you wish) really the peak of quad line design? Have we arrived?
Doesn't it seem unlikely ? In how many fields of endeavour is the first go the be-all-and-end-all ? I don't recall many riders cresting the L'Alpe d'Huez on a Penny Farthing, I prefer MP3s over wax cylinders and even RyanAir would chafe at the idea of using Wright Flyers.
now the patents have/will be expiring we shall see some interesting developments.
There always have been, it's just that making them a commercial viability has always been a tricky proposition. TBH my view is that by making "the Rev." the default for what a quadline is that getting flyers to accept something other
is very difficult. How many people tried an AirBow and dismissed because it didn't fly like a Rev. (which might have been the point, after all) ?
Let's be honest, you could timewarp a Neo's Omega (what Rev. was called before it was Rev.) into now and it'd blend right in, rather than looking like a relic.
My final position was, and possibly still is, personal use fine - commercial not fine.
That's great. But, as in the example I posted, that hasn't
been the position of the patent holder. "The company further advises that the construction, use and/or sale of the quadline kite following the plans, instructions and suggestions contained in the article, whether for commercial distribution or personal use might be an infringement of the company's patent rights."
They don't want you to make your own quadline kites, never mind Rev. knock offs, they want you to buy theirs and theirs alone. And just copying the Rev. design is a) legally wrong b) lazy.
When I first saw these kites I seem to recall thinking "interesting, but the next version will hopefully look better" (or somesuch, it was
a long time ago). But they haven't bothered with "the next version". It's just a bit sad that all it takes to get the quadline flyers excited is a few extra panels on The Same Damn Kite, year after year. I really cannot imagine the same scenario if Dan Tabor had taken the same, restrictive approach and in 2008 all that dualliners had to look forward to was "the Hawaiian Team Kite - now with one half Basic, one half Chevron."
And I note with interest that Revolution were quite happy to avail themselves of Tabor's patented ideas for their dualline kite, the Dodd Gross-designed Phase 2
, but seemed ill-inclined to match his generosity.
What, in a nut shell, is in the 2 Rev patents?
