After watching the Blue Planet discussion with the Duotone Unit designer there was mention that the Unit has reflex in the strut. By joining the two handles you would be getting in the way of the wings ability to do that. The reflex is there so that in a gust the centre of effort moves forward to handle the gust and keep the wing stable. This was just my understanding of what was said - it could be wrong.
Just pointing this out, please don't shoot the messenger.
Thanks MeonAsh,
Yes that's a brilliant interview - so much great information - we have watched that one several times.
Having produced many prototypes of the miniboom we reached the conclusion that it is essential for the miniboom to be able to expand and contract with the wing so it did not impact it. We also found this essential as if it was a fixed item with no play it would pull out when the strut expanded under load. Accordingly that's one of the design elements of an item which on the surface looks quite simple. So even though Reflex was not designed into the Unit (your reference to reflex in the Blue Planet interview was about the Slick not the Unit) wings are made of material which are going to move under load.
As mentioned above, yes, that interview has references to reflex, however, the references to "reflex" are about the Slick NOT the Unit. The timecodes of the reference video (below) start at 1:18:42 "We've had some reflex - quite a bit of reflex in the struct of the 2022 Slick "it made it so the back of the canopy didn't bag out so much", and then more extensively from 1:34.00 "Can you talk a little bit about what you were saying earlier about reflex and changing the reflex of the changed fabrics and so on .." - note that at the time, the cutaway image is of a Unit, but Ken changes the model to a Slick."
Great BluePlanet interview with Duotone designer Ken Winner -
We also found that it's not just the natural flexing of the strut that is important, over time, the material of the strut does naturally settle in with a level of stretch, especially for the 2022 models including the DLAB. It's too early to call for the 2023 editions but all indications from visual inspection and testing is that they have been significantly improved over the 2022 models. One area of note is reinforcement on the strut between the handles. I'm absolutely blown away by the rate of improvement in the wings. Just a couple of years ago I moved from an Echo to a Slick and that was a giant leap. When I moved to a 2022 DLAB Unit that was like a quantum leap. I thought at that point the curve would level out but the 2023 models are better again. Such a fun time to be part of this sport. Hats off to all of those incredible designers like Ken Winner who are making it possible!
Thanks again, really appreciate you bringing this up.
