Title: prism zephyr bridal issue
Post by: nkurilo on March 26, 2014, 12:50 AM
I just purchased a prism zephyr today and when I got it home and assembled it the bridal was all wrong. ... With the bridal adjustment in the center of the limit knots the nose is so far back the kite flies backwards ???? Is this a common issue and how do I fix this.  Thanks in advance to anyone who can get me up and flying.

If you purchased at a dealer, I would bring it back and ask for another one or see if he can adjust it properly.

G,day Mate,

The Zephyr is a low wind trick kite, If you are a novice to stunt kite flying it will do things that in the wrong hands that just does not seem right.

With the right inputs at the exact timing this kite is awesome, I have two but In Australia I only get about 10 days a year to fly in perfect conditions for this kite.

 The days you get to fly in perfect conditions are great but in saying that I have to many kites, It's a highly addictive sport.  Just ask Mr Chilese the godfather of sport kite flying in the US, he is a great mentor for the sport and is appreciated world wide for his insightful wisdom to a unique sport that very people understand.

Cheers
Keith

Im more of a do it myself kinda person and would love the learning experience with this. ..I figured out that if I adjust it about 3 inches above the light wind knot it sits at about the same angle of attack as my 4d and hypnotist in their normal wind setting,  does anyone have the measurements or specs for the zephyr bridal, maybe the limit knots are tied in the wrong place

If you are on Facebook, go to the Prism page and post your question there. They usually monitor that site.

 Maybe the bridle is on upside down, where the upper and lower outhauls are reversed.  Here's a few useful measurements quoted from the prism forum that will test this theory:


"I have a 'Z' on loan at the moment so I just ran the tape measure over it for you.

OK length from Upper APA to first knot (upper outhaul) 475mm (50mm from high to low knots) lower outhaul to HW knot 515mm. I have inhaul at 530mm. Hope that helps 

Now don't be a stranger now 

And if my info doesn't match, pop back tomorrow, I'm sure someone will check to see if I'm right 

Regards,

WD"

In general, the kite spine should be a little bit nose up if you hold the kite by the bridle lines.

If it isn't at least close to this, something is likely wrong.

I had a Z some years ago - it's a decent kite, certainly able to fly and trick easily enough.

Hey thanks for the measurements I'll check them out tonight and let you know what I find.....and thanks again for the help

Here is the best photo I could find showing the bridle on a Zephyr.

It's from 2007. Hope it helps. I agree that when you hold the kite by the

tow points and let it hang, the nose should be a little higher than the rest of the kite.

Well i definitely have a problem then because when I hold it by the tow points and let it hang it looks like it is in a back flip.....lol

Unfortuantely Prism doesn't seem to like making it's bridle measurements readily available unlike some other makers.  Could I suggest you measure and post the bridle dimensions of your bridle here on the forum so that someone compare them with their Zephyr and we can figure out the problem? I suggest measuring from the knot to the frame on each 'leg' would avoid any confusion.

My Prism QPro SUL came with the bridle attached upside-down. So, it's not the first time for that...
The Zephyr is a great kite once you get it adjusted correctly... best of luck.
And no, never fixed the QPro SUL, it has yet to see flight.

Ok so took some measurements But didn't have anything at home to measure in metric hope these will still help.    (It's in inches)
Upper leading edge to low wind knot.....17 15/16
Lower leading edge to high wind knot. ....18 1/2
Low wind knot to high wind knot. ....1 3/4
Spine to larks head on the leader. ....20 1/8

I can see that my lines are shorter all the way around.... is it possible that they put the wrong bridal on or maybe changed the design.

The kite will fly if I adjust it way past the low wind knot

My Zephyr bridle dimensions are approximately the same as yours, and mine flies........ I adjusted to the light wind knot, suspended the kite, and the nose and tail are nearly the same distance from the floor. When I adjust the bridle between the high and low wind knots, the nose is closer to the floor (below the tail). Again, my kite flies, I am surprised you are having problems.

Also, my tail weight is installed.

Is your lower leading edge line longer or shorter than the upper leading edge line?


Title: Re: prism zephyr bridal issue
Post by: missionview on March 26, 2014, 10:23 PM
It is the same as yours, so it is longer.

What wind speed are you trying to fly in?


Title: Re: prism zephyr bridal issue
Post by: nkurilo on March 26, 2014, 10:57 PM
5-8 mph but it was in my backyard so that wasn't the best place to try it...... I may have had wind coming from behind the kite as well as the wind on my back
 Oh and I was using 18' 50# line set

Sorry to be so late with this. My stock Zephyr's bridal is:
 upper out haul, leading edge to low wind knot = 18 inches
 low wind knot to high wind knot = 1 3/4 inches
 lower out haul, high wind  knot to leading edge = 18 1/2 inches
 in haul, spine to tow point pig tail = 20 1/2 inches

I mostly fly with the adjustment half way between the high wind knot and the low wind knot.

Oh, btw the in haul on the Zephyr does not attach to the spine at the T fitting.  It attaches a little lower down through a small hole in the spine reinforcement.

Try flying the kite in an open space using longer lines. I have used 50', 65', 85', and 100' lines, and the kite flies fine.

Thanks for all the help guys I appreciate your willingness to share your knowledge with me..

Hoping for some good weather to come soon it's driving me crazy having a new kite and only being able to look at it. ...... All i can think about is the next time I get to fly a kite
