How to make it

Stunt kite tips for strong wind:

When you fly stunt kites in strong winds you must modify your stunt kite in some form in order to reduce the pull and slow down the forward motion of the kite. This is very essential in competition flying. To fly compulsory figure exactly, you need a slow kite. For ballet your kite should fly at the same speed, no matter how strong the wind is. This means something must be done to slow down the kite in strong winds.

There are some possibilities to reduce pull and speed of your kite:

 



Brakes:

Brakes are two triangles of mesh being fixed between kite sail and spreader. You can fix them between middle cross and standoffs (1) or between standoffs and wing tips (2), depending on kite model. Sometimes they are fixed at the back of the kite (3).

 


A very new method to fix brakes is to put them between standoffs and tail of the kite. I did not test this method now, I saw it at various teams in the last competition at Weston super Mare. More about this method I will write in near future.

Nappies:

A nappies is a stripe of mesh that is attached between bridle and flying line. In most cases (depending of the sort of kite you fly with the nappies) this type of brake is very good. The kite is slower and the pull is reduced. The disadvantage is a smaller wind window (which most of the brakes will do). If you fly tricks the nappies can be tangled with the kite.

 


Vents:

Vents are pieces of mesh in the kite sail. This reduces the sail area which in- turn reduces speed and pull. This is relative to position and size of the mesh.

See examples to position the vents at

 

 

 

How to make them:

Brakes:

Cut two triangle shaped pieces of mesh that will fit into the place where the brakes should be fixed.

If you want to attach them between cross and standoffs, side A has the length of the standoffs, B is the length from cross to the standoffs at attachment at the spreader.

If you fix the brakes between standoff and tail, B is the length from standoffs to the split cap on the tail.

 

1. Cut 2 cm stripes of Dacron ( or 62 g ripstop), as long as the all sides of the triangles

2. Fold the stripes in middle for the whole length.

3. Put the screen between the fold of the 2 cm stripes.

4. Sew the stripes and screen using zigzag stitches.

5. At side A. cut a 3 cm Dacron stripe for use as a tunnel for the stand-offs.

6. Attach a bungie loop at the cross side of the triangle. This will be wrapped around the cross to fix the brakes to the kite.

 

Nappies:

The dimensions of the nappies depend on the kite and the wind strength. For medium effect make one about 15 cm height. For strong winds a height up to 25 cm can be used.

The width of the nappies should more then the distance between the two bridle points. You must experiment with the widths of nappies to find the best results.

 

1. Cut 2 cm stripes of Dacron ( or 62 g ripstop), as long as the all sides of the nappies

2. Fold the stripes in middle for the whole length.

3. Put the screen between the fold of the 2 cm stripes.

4. Sew the stripes and screen using zigzag stitches.

5. Make a loop on one side of the line, a knot at the other one.

6. Fix the loop at the bridle point and the flying line at the knot of the nappies

Now you are ready to fly in strong winds!

 

Vents:

First, you must decide where to put in the vents. In general vents near the leading edge reduce pull and speed. Vents near deepest sail point reduce more the speed then the pull. In addition, different sail shapes will have different effects. So you must experiment to get get the best result.

Here are some examples of good location of vents:

 

There are different methods to sew in the mesh:

1. Method:

Put the screen over the ripstop (approx. 5mm overlapping, right side up) and sew it with zigzag stiches. Then sew a 5mm ripstop stripe over the overlapping screen to get a nice hem.

 

2. Method:

1. Put ripstop and screen right to right and sew it together.

2. Unfold the two layers, put a 5mm stripe of ripstop over the screen and sew it with zigzag stitches.

 

Methode 2

3. Method:

1. Sew screen and ripstop right to rigth, then cut the mesh 5mm along the seam.

2. Open the layers. Put the ripstop in a doubble fold over the screen.

3. Sew it all together with zigzag stitches.
