sting 2.4 brake bridal line length

shehatesmyhobbies - 4-8-2009 at 10:26 AM

Hey all, I just picked up a killer deal on a flexifoil sting 2.4. Only issue is that the way the guy had it set up with the bar set up there is no brake bridal. The loops are there on the trailing edge, but they look as if they have never been used. If someone out there has a 2.4 and could give me some measurements so I can add the brake bridal I would appreciate it. I am training my daughter to fly and would prefer she learn on handles.

Any help would be appreciated!:roll:

Wow.... that's kind of flakey. The standard Sting 2.4 on a bar uses the brake lines and switching back and forth from handles to bars on the kites is a straight swap.

If I am understanding you correctly, he removed the brake bridles entirely? So you need the measurements for all the base lines (bridles attached directly to the kite), the accumulators (the intermediary bridles that gather together the first bridle lines for attaching to the leaders), and the leaders (that actually attach to the brake lines).

I'll check if the Sting 2.4 is one of the kites I packed..... pretty sure it is. If you don't want to deal with a lot of tweaking and trial and error, I would almost say, check with Angus at Coastal Wind Sports to see if he has a replacement on the shelf. Would also check with Angus if you don't have proper bridle cord or are sketchy on the knots.

Otherwise, I will dig up the kite and fend off the cats long enough to take measurements..... Sam and Kite Related Line is a game they dearly love....sigh.

I would not have a part like that on the shelf as it is not a stock item, but let me ask Flexi what they have- at least a diagram with lengths and weight specification. I will write now and hope for an answer in the morning.

acampbell - 4-8-2009 at 12:42 PM

Is that a Sting 1 or Sting 2? It will say on the bag.

indigo_wolf - 4-8-2009 at 02:28 PM

Zoinks.... I keep forgetting about the generations. All my Stings are 2nd Gens.

ATB,
Sam

shehatesmyhobbies - 4-8-2009 at 06:54 PM

Thanks for all the feedback! The kite and the bag both say it is just sting 2.4.No II on the bag at all. The book that came with the kite says 2006. Diagram and lengths and weight would be awesome. The flexibar that came with the kite is only a two line set up. there is no spot for the brake lines. I am not exactly sure how he flew the kite. For $40 I didn't care if he ran around the yard and acted like he was getting mad air. As soon as I saw the kite up for sale I started a barrage of emails that didn't seem to stop. I Hope that I can get some kind of info. I did see a diagram in the flexi book but no lengths or anything like that in there. :dunno:


Indigo you are correct there are no trailing edge(brake bridal) lines on the kite at all.

Again thanks to all that have already responded!

I've got a Sting 2 2.4. I'd be happy to hook up this weekend and let you take a look.

shehatesmyhobbies - 4-8-2009 at 07:25 PM

Dude that would be great! Where is Easton? I am on the edge of the Maryland line, Near Dover and Smyrna. I bet that the bridal lines can't be that much different! Lad is talking about being in town as well. I am not one for going to the beach during the busy season. But I do have some fields over here. I can meet you somewhere in between as well! I will hit you with a u2u before then. I will mapquest Easton real quick!

shehatesmyhobbies - 4-8-2009 at 07:27 PM

That's not that far! only 55 miles or so between us.

indigo_wolf - 5-8-2009 at 05:54 AM

Great googly moogly.... WHAT are all those open fields in Clayton? They would have been scarffed up for development in my neck of the woods.

ATB,
Sam

shehatesmyhobbies - 5-8-2009 at 05:56 AM

These are mostly county parks, only issue we really have is when soccer starts up they just walk out on the field like we are not even there.They just walk in set up their goal post and take over. They pay small fees to use the parks for soccer so we can't compete

indigo_wolf - 5-8-2009 at 06:57 AM

You must have a lot of soccer players in your area to foster any kind of field competition.

Down in the MD (short hop from DC) area for a couple of days. Hoping to get out to the fields over in Millersville some time in the next couple of days.

ATB,
Sam

shehatesmyhobbies - 5-8-2009 at 09:04 AM

Well maybe frankiter has a place to fly near him that would hold the three of us and we can make a go at it maybe saturday or sunday. I am supposed to meet up with him anyway!

acampbell - 5-8-2009 at 10:24 AM

Sorry I missed this thread this morning. I'll ask Flexi for the specs on the bridle

frankiter - 5-8-2009 at 10:28 AM

SHMH, I'm also using soccer fields. I don't have any buggy fields scoped out yet since I'm just static flying for now.


Wolf, Where in Millersville are you flying? That's only 10 minutes from where I work. Are you around this weekend?

shehatesmyhobbies - 5-8-2009 at 12:48 PM

I appreciate it angus! all info I get will be a help. I want to make it right!

acampbell - 5-8-2009 at 05:09 PM

I have an e-mail in tonight and we should have an answer in the morning.

shehatesmyhobbies - 6-8-2009 at 05:17 PM

Thank you sir!

shehatesmyhobbies - 9-8-2009 at 06:56 AM

Well I met up with frankiter saturday to try and get an idea and measurements for the stings brake bridal. No luck, he has the newer generation sting and it has less bridal lines. Totally different! I will continue my search.

acampbell - 9-8-2009 at 08:30 AM

still waiting to hear back from Flexifoil...

shehatesmyhobbies - 9-8-2009 at 09:33 AM

Thanks again Angus! I had Frankiter up here in DE yesterday for a fly. I think you know his brother in law. pokitetrash?

acampbell - 9-8-2009 at 01:04 PM

Sure, it's a small world, especially the kite world!
My Sting is a newer one, too.
I'll bang on their door again in the morning. They have been slow lately.

shehatesmyhobbies - 19-8-2009 at 06:32 PM

I'm still looking for help in this department if anyone can. I would even be up to trading for a sting with handles. All help still appreciated.

acampbell - 20-8-2009 at 05:49 AM

Sorry I let this get by me. They never responded to my e-mail so I just rang them up. They are going to poke around and get back to me if they can find a diagram for the Sting 1 brake bridle.

The more I think about it, though, the Sting is a front line-biased kite. Anything (within reason) that you hang on the trailing edge to give it a tug should work fine without harming the trim of the kite. If we do not hear back from Flexi, take some light dyneema and work up a bridle of your own liking, with the attachment toggle the same length as the mains.

furbowski - 20-8-2009 at 06:26 AM

hmmm. I had to rebuild my sting 1.7 a while back, yes flies great on two lines, but it was easy to fly, try, crash or land it, re-rig, and try again, took about an hour.

if your sting has eleven cells like mine you could probably just take my dimensions and scale them up?

only i had to rebuild mine so i don't know if I got it quite right, never took that all-important photo b4 the debuild!

anyways, that might help....

shehatesmyhobbies - 20-8-2009 at 06:58 AM

furbowski that would be great. Send what you have and I will give it a shot!

Angus thanks again on the flexi try. I am definitely going to give it a go myself!

I just wanted a basic place to start from mostly. Fall is coming, gotta get this thing ready!

Wow, that is a small world! Pokite lent Frankiter his 4.5 Cult and I think the kite virus is starting to catch with him. "Just let em try one and they'll come back for more and more". Pokite lives about 45 minutes away and we have become good friends through kiting.

Pokite and I buggying at the beach and waiting on the wind.



end of social hijack.

shehatesmyhobbies - 20-8-2009 at 08:58 AM

Frankiter came up to DE to meet with me and go fly at the beach as well. He did a nice session on the beamer 7m I brought. I think he is definitely bit by the bug!Really nice guy as well. I hope to get him back here soon or we go to him soon to put him on the buggy!

ok, here goes: there are seven pieces that make up each side of the brake bridle on my 1.7, so that makes a total of 14 pieces of lines in two halves to make my brake bridles.

my 1.7 has 11 cells in total, including two of those little wingtip halfwidth specials. if the cell count is different on your kite then you'll be in trouble. if the cell count is the same, then the kite is likely proportional.

in that case, the measurement for my next to outside cell (the last full-width cell) are 167 mm and for the middle cell 238 mm, as measured along the inside edge of the back edging on the trailing edge (TE) of my kite.

those numbers should help you scale up my numbers to fit your kite.

ok, now we'll work from the wingtip in toward the root (middle) of the kite.

all line lengths are from the outside edge of the tab on the kite to the knot, or from the knot to the knot. the bit larksheaded around the tab on the kite is not included in the line length. the additional length is just less than a cm of the loop or a bit less than 2 cm of line.

the first one right at the corner is 413 mm and goes directly towards the brake leader.

the next two ones in are a short v connected to a longer line connected to the brake leader. the first one in the from the outside is 180 mm, and the next one closer to the root is 230 mm. the longer connection between those two and the brake leader is 425 mm.

the next v closer in towards the root has measurements of 290mm (outer) and 360mm, with the connection line at 625 mm.

I'm going to have a good hard look at that bridle next time out as it seems to me there should be a greater difference in the lengths on the two outside vees, but instead the greater diff. is in the inside two vees. and it seems to me the kite should be flatter near the root and steeper near the tips, not the other way around as the above measurements indicate... I'll have to try switching them around a bit more.... maybe move the longest lines right to the outside and the other longer lines move in one, while swapping the vees around for a better but much flatter curve???

\\ sorry accidental hijack above pp \\

my brake bridle lines are 275 mm and power bridle is 90 mm, with that my lines are equal at the handles.

but i do prefer my brakes a bit slacker than many as i don't yet buggy and just fly static.

anyways do remember i had to rebuild the bridle and may not have got it quite right as i said above...

shehatesmyhobbies - 20-8-2009 at 12:23 PM

Thanks so much furbowski. I am going to get it ready tonight. supposed to be 10-15mph winds tomorrow. I am excited !!!!!!!!!! If I don't get it ready, she will have to wait a couple more days.

furbowski - 20-8-2009 at 12:29 PM

cool.

do remember that i may have buggered it up, but flies ok on the above setting.

main thing is to make 7 pairs of lines with loops at the ends,

bowlines are fine, overhands less strong but tangle less...

pokitetrash - 20-8-2009 at 01:22 PM

Hey!! That picture of me and Beamer Bob is a fake! I have never looked addoringly like that at another dude. Bob's the big goofy one looking back at me... It was actually a retouch of a photo where I met Jessica Alba, so the look is genuine but Bobby and I are really just friends. Really...

As far as stings go, maybe someone can answer this: I was flying a 1.7 Sting 2 in high winds and leading edge bashed pretty hard. It flew kind of "wiggly" for lack of a better word after that. After the bash it shimmied throughout the whole flight, maybe the wind picked up and was too much for the air flow on the foil? I haven't tried it again in lower winds to see if the wiggle is still there. I looked over everything and didn't see any bridle tears, no holes in the kite anywhere, no odd shape to the foil in flight. Could you stretch a bridle flying or crashing hard?

While I suspect she wouldn't hold it against you (for too long), I expect Jessica would be a bit put out that that you retouched a photo of her to "shop Bob into it. Are no memories sacred and cherished anymore?!?! :sniff:

Hmmm... not sure. Is the whole kite "wiggly." The lack or mesh or any real intake reinforcments does allow for a fair amount of front end flutter on the 1.7. Hasn't been problematic thus far. In some ways, the 1.2 seems "tighter" in that respect. When the wind picks up, it just acts like it got another shot of NOS.

Sorry I missed you guys while I was down in DC. Did end up going to the Garcelon Sports Complex on Friday, but the winds were terrible. Next to impossible to keep the Flow airborne.

I should be down that ways again in the Fall.

ATB,
Sam

pokitetrash - 20-8-2009 at 02:58 PM

I'll fly it it lower winds and see if it was just too much for it. I could have buggied that day with it.

shehatesmyhobbies - 20-8-2009 at 06:43 PM

Indigo, definitely give us a shout when you get down this way again!
