How different is the HA to the 1250 or 1650 to ride .....much faster ?
Hey Kobo, I can't tell if this got answered or not.
In general, the higher aspect the wing, the more efficient it can be (depending on its design). This is a big generalisation as all wings are not equal to start with.
HA.
- Are a little more difficult to use in the fast that they are twitchier, faster to respond and in general do not like going sow. But in saying this they actually are able to go slower than the relative wing in a lower aspect under the feet of a proficient rider (as they are more efficient). But if you make a mistake, get too aggressive, not flow smoothly you do risk stalling, kicking or bucking more than you would on a lower aspect wing.
1250/1650.
- These wings are still the best goto wings for a lot/most people. I am actually really enjoying riding the 1250 at the moment as I like riding fast and having heaps of control. The lower aspect wings can be turned more aggressively, behave themselves in a larger variety of conditions and can handle higher AoA at slower speeds. A large component of your drag equation is built up of the leading edge face area drag (i.e. the wider the wing, the higher the drag is in this part of the equation). Then the Surface area drag comes into play, and so on. SO if you have a wing that is 1000mm wide (wingtip to wingtip) (like the HA) wings, they can have a reasonable amount of drag as opposed to a lower aspect wing that is say 850mm wide (wingtip to wingtip). But then the HA's have less surface drag to lift produced. This can be very confusing and difficult to understand - best to just go ride and try as much as you can.
Ok, got off the question a little there.
I use HA wings for DW'ing, they are better for pumping and getting the most amount of lift from any given situation.
I use the Lower aspect wings for high speeds, bigger surf, and harder turning/surfing.
On average I go faster on the JET 1250, than I do on the HA1400. I find I go about the same speed on the HA1400 & 1800 which is really interesting.
I can lift as early or maybe even earlier on the 1250 then I can on the 1400. But I can lift earlier on the 1400 than I can on the 1800.
The 1800 takes far less energy to stay up and foil bumps (DW'ing) than the 1400. And most definitely the 1250.
I can pump the 1800 much easier than any other wing unless I make a mistake. The 2000 and 2450 are easier to get right but will not go anywhere near as fast. The 1400 pumps really well, but requires a slightly higher cadence and faster speed than the 1800. The HA's have a different technique too.
Hopefully not too confusing.
