Use of the term delta is a marketing gimmick, devised to sound alluring and attractive to us wannabee kiters.
Delta wing shape means "triangle shape", don't beleive me then just google delta wing.
The kites being marketed under the Delta name, whether its delta C or just plain delta, even delta bow, whatever, none of them are true delta or delta wing shaped kites.
Delta wing shaped kites look like your traditional pointed nose stunt kite or even kiddies single line kite derr!!

Sorry you have all swallowed the latest guff to make you loosen your wallet.
So moving on from the name.
The style of kite being sold as a delta is a bow derivative, and if you look at any of the early legainoux designed bows, they all had very swept back leading edges and some did meet the trailing edge at a pointed angle.
I think one of the defining things (apart from the planform or shape of the canopy LE and TE combo) about a so called delta style kite is that they do not have a connecting bridle line from the front bridles to the rear lines or rear line bridle.
That is they do not load share with the rear lines except through the canopy itself, and this is the primary reason why the bar pressure is higher than some bows and hybrid bows
All the so called delta style kites I have seen have a forward mounted simple bridle to support the front half to two thirds of the leading edge tube. This bridle is simple and long allowing the kite to depower 90+% when tension on the rear lines is released and all of the so called delta kites I have seen rely on this feature for emergency depower - that is the safety works on both front lines.
There is nothing really C shaped about so called deltas, someone else nailed that when they said the shape has a high projected area (but at first glance it does not look like it). Some of them do have relaunch issues, especially when directly downwind this is more true of the first gen delta kites. I still see them swum in regularly, although more experienced users have more success, they are still difficult to relaunch especially at the lower end of their wind range.
They are all hungy for apparent wind in order to generate their maximum lift, in other words they need to be ridden fast to get max performance, another reason they suit intermediate and upwards riders IMO.
Begginers with good board and kite skills do well on them though.
Open your eyes, don't beleive all the hype and "special name" gimmickry, surely you've all seen enough of that by now?
The shape works, theere are + and - in the design and it does not suit everyone.
Many designers have gone out of their way to make a kite that is a certain percentage different to the original bow designs, yet still having most of the bow style depower and wind range, so called delta kites are the market leader at the moment, in being "different". :-)
Could say more but I'm tired and going horizontal now.
Bandidos and Core Combat GT are the best designs with the best performance and safety systems that I have seen.
T3 is not a delta its a pure bow derivative, look at the bridle and even the fact that it comes 2:1 (can convert to 1:1)
