Raaseri story

Raaseri is a high performance dual line stunt kite designed for individual precision and ballet flying. As Raaseri flies rather slow, it has been used for pair and team flying, too. Raaseri will axel and do some other "radical tricks" but it is not a genuine trick kite.

To build a Raaseri, start reading about the copyright in the construction plan.

Raaseri was born in 1993 when I suggested to n@r.k to build a Tracer like kite as a winter project for Fanø '94 meeting. All five members of n@r.k built this dual line delta stunter, showing national colors of Finland, Sweden, Denmark, Norway and Germany.

Raaseri prototype was flown by many rec.kiters indoors on Fanø '94. Photo of Andrew Beattie flying Raaseri prototype in tennis hall on Fanø (Image size 50 KB) (Photo: Michael Schneider)

Raaseri prototype had Icarex P31 sail and RCF-6 frame, weighting more than 250 g, not a real indoor kite - fortunately the kite didn't know it was too heavy, but flew!

After Fanø '94 I built a set of three Raaseris to cover the whole wind range:

In September 1994 World Cup took place in Le Touquet, France. (I was just a tourist there.) Winds were extremely strong, all top class teams had difficulties to handle them. First time I had opportunity to fly vented Raaseri-H in 25+ m/s winds. Together with Pierre Marzin we had fun to play with Raaseri-H in those grazy winds.

Next week in Dieppe, some asshole realized how good kite Raaseri-H was, and stole it from my kite bag, when I was flying my ballet demo with Raaseri-M on the main arena.

I flew Raaseri-L in European Cup '94, St. Moriz, both in individual precision and in ballet. I didn't score very well, but it's not the fault of the kite! Raaseri tracks and turns very precicely, even in slow speeds and on the edge of wind window. It's also radical enough to be used in freestyle and ballet.

Raaseri - what does it mean?

Rouben Ter Minassian made one page plan of Tracer like kite in 1992. He gave it a French name: T'a Soeur, which sounds close to 'tracer'. I continued the joke and named my version to Raaseri, which is a Finnish slang word for 'racer'. When I gave the name in 1993, I didn't guess Raaseri will be my primary competition kite on the following season(s).

For Fanø '95 n@r.k had a small batch of Raaseri pins made. They had the same colors as the kites in the n@r.k family portrait.

Raaseri vs. Tracer

I suppose Raaseri has somewhat same main dimensions as Tracer. (I have never took any "reverse engineering" measurements from a Tracer), but differs in:

Happy new year and always Smooth Winds from behind!

It's really time to report my experiences with the Raaseri. 
Up to now I have built 3 raaseris. For the first one I used 
a different panel design and made an error with the leading 
edge:-( I enlarged the kite 2cm along the LE. I used a cheap 
6mm cfk frame and got a not a very good kite, but had also 
fun with it. 

I built the second one exactly as you described and it flies
really great. The best stunt kite I ever had on my lines.

Hi Simo!

My name is Nino Gualdoni and I am an italian kitebuilder and 
kiteflyer. I have seen in your home page the description of 
the raaseri and downloaded the plan in postscript format. Of 
course i have built the kite and... it flies great, great 
and great. Gratulations! 

Maybe, raaseri will be the new light wind kite for my team 
(The Rin Tin Team) instead of the Phantom. Really, you made 
a great job.

Hi Simo

I'm Paris suburbs kite flier with tramontana, trix, skylite, 
rev1.5 clone, aerial pseudo clone, home made roller, home 
made 3/4 stunt delta (for my son), ultra mini mono delta 
(for my daughter), eddy (for my wife), and strong dependence 
to kite flying and making... 

I'm pleased to announce you a new version of your original 
raaseri. With your permission i'll name it "raaseri baby" : 

   * 1.3 m wing span (0.6 reducing ratio)
   * P31 sail
   * CX1 leading edge
   * 2 mm rods
   * Topline 25 kg bridling
   * 12 kg spectra lines
   * around 45 gr weight
   * and a nice shape

My objective was to made an indoor/light wind small kite and 
my first flight reveals a very good potential.(and maybe 
somes tuning) 

I exactly follow your bridling instructions but i'm not sure 
that cross bridling fit to a so small kite like that. I'm 
inexperienced with indoor/small kite flying but it's over 
react to my actions. 

I notice that the depth of the sail at wiskers was around 16 
cm. Isn't it a little too much for 1.3m span ? 

Tanks you very much to help me and for your plan on the net.

ps Forgot to say that I got the mini-Raaseri finished and it 
flies very well indeed.  It is remarkably stable for such a 
small kite (about X4i size), and will axle, float and still 
tracks very straight.   I was surprised but pleased with the 
results.  I sparred it in 3mm in the end, and it seemed to 
be a good all round compromise.   Thanks for your help with 
the plans.

Hi Simo

We finally got our Raaseri to a stage were My wife and I 
could try it out for the first time.  The wind conditions 
were very light 2-3 kph max.

The kite soared up into the sky first time, and flew very 
well, at least as well as my Pro Comp Tramontana.  We are 
very pleased.  My wife (who did all the sewing) was jumping 
for joy.  This is a really great kite.

Thanks for all the help you give, and for a truely 
fantastic kite design. This was the very first kite 
we have made, we are very pleased with the results.

Thanks again for making it easy to make a really 
great kite.

I there is one problem, it is next to impossible to make that kite so
it works very well.  I am one of about 15 people i know who have made
this kite and our suscess rate is horrible.  So good lucky, ask Simo

Check the bridles again. I haven't seen the plans, but maybe they are incorrect
with the bridle you are trying to use.

In any case, what you describe is often an indication that the bridle is set too
low. Try shortening the top bridle line (the one that goes to the top spreader)
or lengthening the bottom two bridle lines. The outhaul (the line that goes from
the point where you attach your lines to the lower spreader) might be too short
as well. It's hard to know just by your description.

If you are using fabric for your kite, then you really don't need to use adhesive.
There are problems with some adhesives. When you are using films and film
laminates, like Prism does with most of their kites, you have to use adhesives,
otherwise the films will tear.

What you really need is just to practice sewing. After a while you will be able
to sew most things without help from adhesives.

It's a fine kite once you get everything worked out.

Newsgroups:   rec.kites

Hi Everyone,

Just a short note to say a heartfelt thankyou to all who 
responded to my "Raaseri wont play" post.

After reviewing the information offered I changed the 
x bridle and created a dynamic item and added two more 
stand-offs. Went out this afternoon to evaluate what, 
if any, improvements had been made. Straight out of 
the bag and into the air. Much lighter crisp performance, 
still moderately slow but thats how Simo designed it to be.

This is a brilliant novice kite. Thanks to Simo for 
putting the designs on the net. If anyone who responded 
that they too had terrible trouble with this kite would 
like more info and measurements of the changes made, give me
a shout. I must note that the original designs are by 
Simo Salanne and as such acknowledge him as the owner 
of these designs and hope that he doesn't mind me altering 
a couple of minor items. Changes were forced probably 
due to my crap construction techniques, but they are 
getting better.

Again many thanks everyone.

Phil H.

Well I was all worried last week when all the comments were flying
about the Raaseri kite design by Simo Salanne.  I had just started
laying out the patterns for this kite when the discussion on this
group started. Needless to say I followed the threads fairly closely.
Well it all came out fine in the end, and my kite was finished
Wednesday October 15th, so I bravely took it to my favorite flying
area (the local community college socker fields), hooked up a set of
lines, took a deep breath and give it a pull. It jumped into the air
and flew great!!!!!!!! I was grinning from ear to ear, this was my
second attempt at building and first attempt at a dual line stunt
kite.  So if you are thinking of the Raaseri design GO FOR IT!!.
Its a very good kite. Mine is built as vented model and you can see it
at http://www.netsync.net/users/alee/kites.html.

Sorry, I have to disagree with this.  The Raaseri is one of the
most forgiving kite designs you could find to build, particularly
as it has a low-aspect ratio which seems to provide a lot of stability.

I have made three versions, each time I have changed the plan quite
randomly (remodelled trailing edge, different bridle) but still
ended up with a kite that flies beautifully from day one.

The design will tolerate a lot of error before it becomes

Perhaps you folks are struggling with the cross-shunt bridle

I think I'd prefer the Raaseri.... Easier to build and 
same but probably better performance..

The Raaseri is a derivative of a very successful kite called
the Tracer, by Mike Simmons.  Raaseri is more refined, and has 
a better bridle.  The Tracer was a very popular competition kite,
particularly in precision, as it tracks superbly (deep sail).

The Raaseri is certainly comparable to current many commercial designs
both in terms of performance and features.

It does trick fly, but it would not be considered a trick kite,
as it performs most tricks quite slowly (flat spins are a doddle
with the Raaseri).

The Tracer was about 150 UKp in it's day, more modern comparative kites
might be the Airmaster AM-1, which is closer to 200UKp.

It's a good all round kite, excellent for precision, but loses
out to more recent specialist trick or team kites.


Subject: Raaseri bridle types
From: michael.emery@stack.inet.fi (Mike Emery)
Date: 1999/01/05
Newsgroups: rec.kites

This is a description of three types of bridle that I have used on my
Raaseri. Each measurement is point-to-point and makes no allowance
for knots (esp. for the ACTIVE BRIDLE) or loops for attaching to the
frame. These tend to vary with material used and preferred knot
anyway. In each case the standard bridle attachment points as per the
plan are used.

I would stress that these are *MY* bridle settings and you may find
them not to your tastes, a fact that may be backed up by a
conversation I had the last time I was in the UK with a well known
(if nameless here) flyer trying out a Jester 2 with my dynamic

Mike:  What do you think then ?
Flyer: 'Snice.
Flyer: When will it stop spinning ?
Mike:  Soon. Soon.
    [another pause. Quite a long one actually]
Flyer: It hasn't stopped yet.
Mike:  Well....it's slowed down a bit.

Consider this fair warning. Personal taste is just that.

The references and acknowledgments are to those who I believe to be
responsible for the concept of the bridling system in question.

The original cross-shunt bridle for the Raaseri is by Simo Salanne,
designer of the kite.

CROSS STATIC BRIDLE (after Don Tabor, Mike Simmons et al)
Basically as per the plan but I make no use of the shunt leg which is
normally loose anyway and I also make the outhaul one continuous
length rather than making each leg adjustable for ease of
adjustability and symmetry.

Inhaul x 2
Note: Inhaul runs from lower spreader, across the spine and joins to
the outhaul at the tracer. This is the fixed line.

    |                             |
    | <--------- 81cm ----------> |

Outhaul x 2
Note: Outhaul runs between the upper and lower spreader attachment
points on the leading edge. This is the adjustable line.

    | <------------------------ 117cm -------------------------> |

Tracers x 2
Note: Tracers are used to attach the flying lines to the bridle and
are loops of bridle line tied into an overhand knot.



DYNAMIC BRIDLE (after Ray Bordelon)
For a low aspect ratio kite like the Raaseri with so much pitch
stability some "fore and aft" moves like Fades, Flic-Flacs, etc. do
not come easily. The dynamic bridle allows a little instability to be
added. Too much dynamism in the bridle leads to a loss of that nice
Raaseri precision.

    | <------------------------ 116cm -------------------------> |

Tracers x 2

ACTIVE BRIDLE (after Andy Wardley)
Not especially easy to tune and if I had the time and smooth winds
for the task I would work more on this but I am quite happy with it.
By making the lower legs on each side from one continuous piece and
making the upper leg adjustable in length you can tweak this bridle
quite fully (ie; more oversteer move Stabiliser point outwards along
lower leg, lengthen upper leg to increase pitch). However, this
bridle type is a manifestation of the fundamental interconnectedness
of all things and changing just one length to improve one flight
characteristic tends to mean more changes to gain back lost ground in
other areas that you didn't want changing...which means more changes
to other bits.....which....You get the picture.
