Sluggish Controls
Top

Hello, fellow kiters.

I was flying a borrowed kite today. It's a cheap-o nylon delta stunt kite.

My question is this: what could be causing the sluggish controls? While I was flying the kite, just to make a large turn (either left or right), I had to throw one arm all the way back as far as it could go and let the other line fall completely slack. The kite is rated for winds 7mph to 18 mph. I was flying in about 10mph to 15mph winds (on average). Could it just be the wind speed, or could something on the kite be tweaked?

Stephen.

Hi Stephen

It's a little hard to say without having actually flown the beast, but in general, and in my fairly limited experience, the large turning radius you describe is due to one of two things.

Either the bridle is set too light (too nose forwards) or the tow points are too far out (too far from the centre-T).

To correct the first, make the top leg of the bridle longer. This has the effect of pushing the nose back away from you and will make the kite turn more tightly. It will also make the kite more "tricky" -- stalls, for example, are easier to initiate and maintain with a heavier bridle. A heavier bridle will also give the kite some oversteer, the actual amount depending on the length of the top leg of the bridle and the wind speed.

Alternatively, you can move the tow points in towards the centre-T which will enable the kite to turn more tightly with less arm movement.

As with most things in life, nothing is for free. For example, by pushing the nose back you will not be able to fly the kite in as light a wind as with the nose set more forwards.

The best description that I've come across on the web regarding bridle adjustments is Allen Stroh's bridle tuning tips page. http://home.san.rr.com/kites/tuning_tips.html This treatise on bridle adjustments is written for PBSKites but the principles apply to other makes of kite. You might also consult Any Wardley's http://www.kfs.org/~abw/ for a description of how to attach as much "string" as possible to a kite :-)

Hope this helps.

Er, is this right? It seems logical, but I think the kite becomes more precise with tow points towards the 'T' piece, and turns more tightly with tow points AWAY from the 'T' (towards the wing tip).

Just thinking about a tip wrap - the tow point effectively goes towards the tip and away from the 'T', that kite starts to do the tightest pull turns - doesn't it?

I think ABW's cross activator has the same effect as it 'automatically' moves the tow point in or out depending on the line input:-

" Straight flight - With equal and firm pressure on the lines, the kite tracks well as the bridle locks into a position in which the tow points are moved inwards. Turn/Spin - Increasing the pressure on one line will move the tow point out to a position where the kite spins fast and smoothly." http://www.kfs.org/~abw/kites/active/dihedral.html

I'm still working out the full design aspects of a sport kite, but I'm sure someone can give the definitive answer.

Thanks

I've got to admit that this one confuses me a little too. All I can say in my defence is that it seems to me that the point about which the kite spins is more inboard the closer the tow points are to the centre-T, hence the turns are tighter. If the tow points were actually both attached to the centre-T itself (or very close to it) the kite would spin about that point. It might be a little hard to control though! Conversely, if the tow points were an infinite distance apart the kite would not turn at all. That's how I see it, anyway.

Not when compared to the two ridiculous examples above.

I've gleaned most of the little info I know about bridles from Allen Stroh's web site. None of my kites have active bridles as yet so I can't really say much about those... but I will in a moment anyway :-) (I'm currently waiting for one for my Illy and will buy either a Gemini or an Elixir one of these days - can't decide which.)

Andy's active bridle design also moves the tow points up and down as well as in and out depending on the amount of pull on the line -- a slack line will allow the tow point to move out and down. This -- the lower tow point -- obviously has some effect on the kite's turning radius as it makes the bridle effectively "heavier" thus making the kite more radical and increasing the amount of oversteer. (A tip wrap moves the tow point down by a fairly large amount as well as moving it out.) With taut lines, the bridle is made "lighter" which aids precision as the turning radius is made larger.

I guess it all depends on which factor has the greater effect on the kite: the in / out position of the tow point or its up / down position.

I've never really experimented to see how tow point movement affects precision; I'm just speaking from memory. Some field work would seem to be indicated, but I'll try to avoid your tip wrap scenario whilst I'm experimenting!

I think I'd better stop now before I confuse myself even more and make an even bigger fool of myself :-)

Andy, we need your help here if you're listening.

Hi James,

I've had a go at adding ABW pitch-activators and cross-activators to standard static bridles. Very easy just tie on (triple-wrap slip knot!) a bit of bridle line between two of the bridle legs about halfway down so that they are pulled together a little - then just fiddle with distances and lengths.

I found that the pitch activator helps a lot by 'automatically' adjusting the kite for high and low wind, but I took the cross-activators off as they changed the standard bridle into an overly radical turn rate (for me) on the Stranger (I like to fly a bit of precision with the Stranger :-) - also had similar experience with Matrix but then again I don't like the standard dynamic bridle set-up and prefer the feel of the static. Conversely the dynamic bridle on a Prism 3D seems to work very well thought - confused?

Any help or comments greatly appreciated as always.

Thanks
Alun J.

Hi Alun

I had a quick play with my Illy's bridle (non-active) yesterday. The kite definitely turns more tightly with the tow points pulled in. The wind was very light so it was a bit hard to really get a good idea of what was going on or how the kite would recact in a "normal" wiind. The tow point adjustment at the Illy's centre-T also has the effect of altering the angle of attack which, of course, affects the spin tightness.

Sounds like an awful lot of fiddling to me.. which I'm bound to muck up. I'll wait until I get (eventually) the active bridle that I've ordered. I might well experiment with a few spare lengths of line on other kites though.

Confused? Of course I am! I like my little 3D and wish that I was able to fly it more often. The wind here (S. coast UK) is often too high for the it. The 3D would, IMO, be quite a good kite to experiment on as regards the various tow point positions. It's easy to adjust... and you shouldn't have to walk too far back to the kite when you decide that your changes don't work. :-)

James

In general, moving the tow point towards the wingtip (i.e. down and out) will increase the kite's tendency to turn, making it turn faster and tighter but with more oversteer. Moving the tow point away from the tip will reduce its sensitivity, give better tracker but larger turns.

There's only so far you can go in any direction before the rules stop working. If you move the tow point too far towards the tip or leading edge then the kite will totally wash out in the turn. Too far in and it might not turn at all. Too far up or down and the kite probably won't even get off the ground.

This is something of an over-simplification, but it beats the complex explanation. :-)=

hi Stephen

as well as the good points James made, don't forget the quality of the flying lines. If they were "free" with the kite, they may well be thick, heavy, and stretchy. See my NEWBIES web page for more details.

cheers - tricky dicky

Just to throw a different slant on this discussion, is it not just possible that the lines supplied with this kite are just cheap polyester flying line and are just too stretchy. You get what you pay for. - Dave

Adding ABW pitch activators and cross activators to a standard static bridle really is easy - honestly. If the bridle is set up as you like it, adding a pitch activator will tilt the kite 'automatically' and really help out in low winds and stalls. If the effects don't please, it's also easy to take the extra pieces off and return the bridle to standard. The only difficult bit is having enough time and *weather to do everything I would like to though :-)

Like you say, the latest kites come with advanced bridles and are ready to go - way cool.

Big thanks to Andy for taking the trouble and time to respond - I'll be trying pop lateral this weekend* as fade flic-flacs are my fave.

Bridle or Technique
Top

Hey there... i have been flying with an HQ Passion lately and find it incredibly hard to pancake... this is frustrating because i'm trying to learn a flat spin. Anyways.... my question is should i make an active bridle for this kite? Has anyone tried it? Any tips or advice? Are there other bridle options? How can I make the kite more radical by adjusting the bridle in it's current configuration? is there a way even?

Thanks a lot!

Alot of people have focused on bridle, frame, etc. I think the question you should be asking is what am I doing wrong, rather than what is wrong with my kite. Good technique will always out fly gadgets and gizmo's. Now if it was cornering that would be different, as the passion will feel very different with different bridle settings. Anyway back to your question.

The problem I see most with people doing pancakes is that they are trying to use small movements in their arms in wind that is probably too much for them. So what does this mean? If the wind is higher, try it off to the side of the window. Also you can over come the pressure by speeding the kite up as it goes down. This will allow 2 things. 1) Your kite speed will be beyond that supported by the wind so it will be easier to luff. 2) Your arms will be behind you allowing you to throw them farther forward when you go for the pancake.

To do a good pancake can take alot of forward arm and body movement. Try this:

1) dive and sweep your arms back with a step back. Time it so that you dont crash doing it.

2) When you have pulled back as much as you can, throw your arms forward while lunging forward. You can lunge faster than you can run, so hope this is enough for the wind you are in.

Your hands should move about 8 feet in 1 second assuming you are an average adult. The entire trick to getting a pancake is the speed into it followed by fast slack. If it wont pancake it's because you cant slack it fast enough. If you dont believe it try this experiment. Dive it toward the ground and accelerate. About 10 feet from the gound let go of your lines. Watch your kite pancake, and then chase it down the field. You may even go past into yo yo. The only difference is how much you speed it into the dive and how fast you can release it. Passion is not a very difficult one to pancake so you should be able to learn this with some practice.

Walt

Hi Dave,

First let me say that I agree with everything Walter said. The fact that you said you are trying to learn the flat spin tells me you may need more practice. In time you will be able to pancake any kite, in almost any wind no matter what the bridle setting.

But, I believe that you will learn faster if you are able to flatten out the kite. So to answer your question, no I would not recommend building an active bridle. The bridle on the kite is fine. The Passion is an excellent trick kite, it requires larger movements than some, but still a blast to fly.

To answer your second question, yes, there is an adjustment to make on the factory bridle to make the kite flatten out easier. Generally a kite is setup at the factory for its average wind speed. The basics of bridle adjustment are, move tow point up for lighter wind, move tow point down for stronger wind. There are many other factors but that should get you started. Moving the tow point up gives more lift but makes the kite turn slower, moving the tow point down puts the kite in more of a stall attitude and makes it turn faster. You will find that any adjustment you make to the bridle to improve one characteristic you will effect another.

Getting to the answer of your question, move the tow point down to make the kite flatten out easier. Begin with small 1/8" adjustments and continue till you get the desired effect. The wind speed will play a big factor in the ease of tricking. Trick fliers like light wind because it allows you to manipulate the kite at will without having to fight the wind.

Hope that helps
Mike Coons

Hi Folks.

Good advice all round, as usual.

I had one of the first Passions to play with. I found that on the factory setting it was a great all-round kite (A good job done by Alex Hesse of HQ). I could do all the things I wanted to do, but I still wanted to fiddle.

I ended up moving my bridle down by about 2.5cm and out by the same. The second move kept the steering the way I wanted it. The problem with dynamic bridles is that you need to do two movements if you only want one change to take affect.

But as everyone says. The best thing to do is practice, practice, practice. You can do it big boy ;O)

Chris.

Hi Dave,

All I have to say is Mike and Walt are correct. I own a Passion and I can do most tricks just fine with the stock bridle. In the years I've been flying I have found that its mostly practice and developing the proper technique for the trick. Finding other flyers to hang with helps too. The 540 Flatspin took me a while to get, but its a most impressive maneuver.

Peace & Good Winds to all,

Ted

Yes, I've been there too. I agree with all the advice others have given, just keep practising and practising and pr... you get the idea :-)

I found it to be a kind of leap of faith. Flying your kite straight down and throwing your arms forward fast enough to pancake - you know the first few (many) times tried, it just keeps heading straight down, and then becomes a battle to turn before hitting ground.

Once the speed/technique/muscles have been acquired to pancake it becomes second nature, and you will know exactly what is required to achieve a pancake for the given wind conditions.

Starting out, it is much more easy to pancake in light wind. When the kites at the bottom of its wind range, and you are doing a fly-away walk a bit too fast and it pancakes when you perhaps didn't want it to..so the higher the wind the more fast a throw forward is required.

If the kite is in a 'nice' wind, point it downwards while pulling both hands way behind your back, start to walk forwards and then try throwing your arms forwards. That little walk really does help in higher winds.

When I started to pancake to go into a Fade rather than half-axle to Fade, my arm and chest muscles would ache for the next week, and I noticed that my upper chest muscles have now changed shape! (a bit ;-)

Forgive me if you know all this, and were just after specific bridle information, but my take is.. to become a good (sport) kite flyer, things should be learnt at the most basic level, so that any kite can then be appreciated.

On the other hand, some kites do pancake more easily than others, so you could say learn a move on a kite that it is easily achieved with, and then it will become more easy to transfer that knowledge to other kites. There have been posts relating to the back-spin and this point of view.

I was discussing the pancake/540 at my local flying field this last weekend, and one comment was "throw the lines at a (Benson) Outer-Space and it will pancake and 540.."

Me, I'll just keep muscle building with the Matrix and Stranger for the time being :-)

Alun J. (UK)

Whenever I teach someone to 540 the thing that always nails it is using their feet to get a better kill. Walt kind of said this but I'll re- iterate it because it is important.

Say your flying down, slightly toward the left hand side and you're going to pop the 540 with your right hand...

As you fly the kite down you want to accelerate it just before the kill, as well using your hands swing your right foot back so your left foot well in front of the right and pull your hands right back on the way down. Now when you kill the kite take a big stride forward from your left onto right foot as you throw your hands forward. That way when you kill the kite you throw the lines forward the distance covered with your feet plus that with your hands ie: about 8ft so you get a great kill without running forward too much.

Keep at it, it's not an easy move to learn but it is one of those where once you've done it a few times it comes quickly and easily. -- Ian Newham
