I think the Vegas is the same way. I would ride both the naish & vegas on the high Y. It's simple enough to double the power of the Y line just run a double line instead of a single. it will have just as much drag as the V configuration in 5th line mode. It's sloppy tho running two lines, so I would do what dracop is doing, except I would probably go straight to 3mm line. Remember this is a 5 line bar so you don't have to worry about the doubled line having to fit through the safety the 5th line does that.dracop wrote: As far as V vs Y, that would open the canopy up differently, not sure it would work well for the Torch as the kite is very sensitive to canopy shape.
well if you do the full calculation, say you have 22 meter lines, 5 lines, lets include the kite for drag, the cross section of the leading edge of the kite is around 1 or 2 square meters on a 12 meter kite, depending on lots of factors (lets call it 1 square meter that's a worst case scenario) then you have 1.6mm diameter line with the 2.2mm Y part, so the total area of the lines is 0.0016 * 22 * 3 (rear lines + 5th line) plus 12 * 2 * 0.0016 for the Y part near the kite then 10 * 1 * 0.0022 for the thin Y segment you are buying for a total of 0.166 drag for the lines that a significant amount of drag, something like 15% of the total drag here is in the lines. Now I'm not doing the coefficient of drag obviously you need to calculate it for the the kite and for the long cylinder lets just leave that for now and continue see what we get. With the 3mm line you get a number of 0.174 for the surface area for the thicker 3mm line and a total of 1.174. Let's see what the difference is: 1.174 - 1.166 = 0.008. 0.008 / 1.166 = 0.7% more drag in the 3mm line. I suppose you might notice it but it would be difficult. Like I said I would just go with the 3mm. For differences this small it's hard to really tell by flying the kite. That's just doing your 2.2mm line vs my idea of a 3mm line. Should have run the numbers for 2.5mm oh well, anyway it's less than that.dracop wrote:2.5mm line vs 1.6mm

Or you could give up kiteloops, then you'll be fine with the original lines
yeah the new woo and xensr have g force trackers, the problem is you hit these 7 to 10 g force landings and you dont care about that you want to track g force on liftoff so I'm not sure how you can sort out all the g forces. Looks easier to do on the xensr. But yeah 2, 2.5 3 g's that's in the right ball park. It sounds like a lot but really not a lot of force. 3g on the spreader for you is 330kg or 730 pounds, and I'm sure you've gone over that from time to time in a crashed kiteloop. It takes more than 700 pounds to straighten out a spreader hook, and I'm sure you've done that before. When you have a hard landing and smash a board in two that's probably over 10g's force, or 1,100kilograms, or one and a quarter tons. There's no point in making the lines too strong. somewhere around 600-800kg per center Y or 300-400kg per individual line is enough where other parts of the kite and harness start failing. But I do think it's worth it for you to go all the way up to 600-800kg per center and 300-400kg per line. Less swimming. By the way I know qpowerline is rated at 272kg (600 pounds) but it has always felt stronger to me for some reason and I haven't yet snapped a q-power line.dracop wrote: How would I calculate the g-force in a powered kiteloop? No idea how to begin to tell that. Does the woo have an accelerometer that will tell you this?
