The Turkish flight arrows from Kviljo Buemakeri are among the very best in the world. The arrows are based on a set of original arrows from the 1700s, and are copied down to the smallest details. It was with these arrows that I set four world records in flight archery in 2019.
 
The arrows are made from pine or spruce, with so-called "Bakkam" nocks, wrapped with sinew, and with a point made out of bone. The nock has a strong original-type "snap-on"-function, with an inner width of approximately 2,75mm. You can choose between feather fletchings in the color you'd like, or with paper vanes like most of the original arrows. Specify also the desired arrow length - from the shoulder of the point to the bottom of the nock (the point is approximately 7mm long). The original length is about 24 inches, but the arrows are made from 21 to 28 inches. Suggested length is between 23 and 25 inches. The arrow weight varies between 140 and 280 grains.
 
The pull-down menu "deflection in millimetres" refers to the spine of the arrow, which needs to be chosen according to the draw weight of the bow as well as the bow type and efficiency. The spine of Turkish flight arrows is measured with a two-pound weight, with the shaft resting on supports 22 inches apart. The deflection is then measured in millimetres. The smaller the number, the stiffer the arrow. Choosing the right value is part of the game here, and since there isn't an established standard for this, it is a bit of a guessing game. A heavy and fast bow needs a stiff arrow, while a lighter and perhaps less efficient bow can be shot with an arrow that is less stiff. If the bow has a brace height of less than 6,5 inches, it is wise to choose a slightly stiffer arrow, while a higher brace height will allow a less stiff arrow to be safely shot. If you are buying more than one, choose different specifications for each arrow, to give yourself a better chance of hitting what's optimal for your bow and your technique.
 
You can choose between "Light", "Medium" and "Heavy" in the pull-down menu "Weight category". This refers to the total weight of the arrow, and are relative values only. It is not possible to order arrows with specific weights. If you've got a very fast and efficient bow, you will get the best results with the arrows from the "Light" category, while a regular target-bow will need arrows from the "Heavy" category to function well. These categories are to a large extent also deciding the price of the arrow, as there is very limited access to material that will make it into the "Light" category. Most of the arrows that I make will either fall into the "Medium" or "Heavy" category, and the price is set accordingly. 
 
It is the arrows from the "light" category that will give the longest distances - if you have got a dedicated flight bow that is made to handle lightweight arrows. If you don't have a dedicated flight bow and just want a nice set of flight arrows, I'd suggest to choose arrows from the "Heavy" category, as these are priced lower. All the arrows are made to the same exact standards and with the same high finish - and look identical, apart from the weight/thickness and stiffness.
 
Some examples:
A very efficient Turkish horn/sinew composite flight bow of 80 pounds at 27 inches, can be shot with 24 inch arrows if it is used together with a traditional overdraw (siper). Arrows from the "light" category needs to have a deflection of at most 18mm to be shot safely. With arrows from the "heavy" category the deflection needs to be no more than perhaps 16-17mm. If the bow is to be shot with full-length arrows and no overdraw, the deflection may need to be 15mm at most. A similar bow of 45 pounds can be shot with arrows that deflect up to 25mm, while a very heavy bow of 130 pounds likely will need the stiffest arrows of 12 or 13mm deflection. If you want a little extra safety margin on the arrows, choose a lower number.
 
Note:
1. Make sure to widen the nocks adequately if you are going to use a string that is thicker than about 2,6mm. The nocks are about 2,75mm at the widest, but have an opening of 1,5mm, like the originals. This gives a very solid "snap-on"-effect, but the nocks can break if they are put onto a thicker string. There is no warranty against this.
2. The arrows are best suited for bows with a brace height of 6,5 inches or more.
3. Paper-vanes should not be shot directly over the hand. Use a leather glove, or a traditional siper to protect the hand.
4. Generally these arrows have a low safety margin. The arrows are extremely lightweight and thin, and they can break during the shot. It is strongly recommended to use adequate protection. The arrows are shot on your own responsibility. It is wise to practise a clean release with regular arrows. A bad release can lead to an otherwise optimal arrow breaking during the shot.
5. Not all bows can shoot these lightweight arrows safely. Even the arrows from the category "heavy" are very light weight, and shooting them can lead to damage on your bow. Ask the maker of your bow if it can shoot arrows of about 200 grains weight.
