Testing the worlds fastest 90 pound traditional bow

This video shows a Turkish glass-laminated bow being shot for distance while the arrow speed is measured as well. How far will the arrows fly at a certain launch speed? The best shot pf the day went 544 meters, having been ahot at 338 feet per second.
Ps. regarding the spine testing of short flight arrows like these, the supports of the spine tester should be 22 inches apart, not 26 as I mentioned in the video. Standard spinetesters operate with 26 inches, but this is naturally not possible with arrows shorter than 26.

Great test. about 65-68j or ke with ultra-light arrows. Very efficient bow with low gpp :) The variation of distance could be a lot of factors including the release. Arrows that kick off the bow (go sideways) will take longer to stabilize losing initial speed faster than cleaner releases, as they create more drag in the first moments of flight. But brilliant video and great demo. Loved it.

Hello Ivar, I love the video! Also, you did pretty well shooting from your knees to place the arrow right over the chronograph.

@@alancase1745 once I managed to shoot a chronograph...using the shooting machine 😆 I always felt it was difficult shooting over the chronograph by hand, but I think it helped a lot that there was no specific landing zone/target I had to align against as well.

I did some flight testing with a crossbow and though I initially thought the best angle to shoot would have been 45 degrees, in fact the best angle turned out to be 39-40 degrees and from 41 degrees onwards the distance started dropping. I also gathered that a change in angle by 1 or 2 degrees under or over, can make a sizeable difference in distance. Plus I found it to be very arrow specific using numbered arrows and with near identical weight arrows performing slightly different. Some arrows worked better for unspecified reasons..which told me that testing will often provide a 'favourite arrow'. I used a home made device to give me pretty accurate angular measurements, to help with consistent shooting.

@@vincentsmith8328 That's pretty awesome! Thanks for sharing that. I have wanted to test the same as well, but never got around to it.

@@kviljo Modern artillery find max reach at 43/43,5 degrees. Guess theres more drag with the arrows, esp with the flexion after launch.

@kviljo Ай бұрын

@@peresteinpris-rhjell693 interesting! Something must make up for the difference here, somehow, I think. According to Adam Karpowicz (who quoted someone who had done simulations), the arrows should go farthest if shot at 39 degrees, and towards this lower end especially for the higher speeds. I wish aerodynamics was more intuitive 😅

I mentioned it in another one of your videos, but the "FX Archery Chronograph" is a really nice, compact doppler radar chronograph that I've used to measure the speed of arrows and even stones. Highly recommended! It could be useful.

@kviljo Ай бұрын

Thanks for the tip! I will definitely consider it when my current one is shot or dies in other ways... 😄

The radar chronographs are really nice and convenient for getting data out in the field like this. I got a good deal on the new Garmin Xero C1 Pro chronograph and it is pretty awesome. Is the FX Archery Chronograph the one that has an audio output? I really like that feature! It can be really difficult to read the output on a display screen under the blinding sun light at the high desert dry lakes where we shoot.

greetings to you sir and everyone.i am enjoying your videos as well as very curious about your bows to.they are very well build to shoot at that far distances.thank you and all the best for you in the future🙂👍

Great video! I wonder if the longbow shooter would get more speed if he shot off the far side of the bow. You can see in the slow-mo he is executing khatra (unavoidable with good draw form, which he is using). Since he has the arrow on the near side, the khatra is causing a lot of arrow slap/deflection against the handle. I wonder if it might pass the handle cleanly on the far side and get a smoother flight with more range.

@@suunraze This is something I have wanted to try too! It may well give a noticable advantage

@mrln247 Ай бұрын

Suspect there's a lot of optimization to be had with technique and the arrows themselves. Don't know what spruce you are using but Stika spruce is considerably stronger than the normal European (Norway spruce) species. Wonder if hardwoods like Hickory might be worth investigating, being springy and having thinner for the same weight.

As i consider you one of the best to ask this: I shot cloud in the past, back home in the Netherlands. Never been able to shoot flight anywhere.. Normally shot at about 42 angle, long parabolic flight. Some however, fast bow, shooting 5/16th arrow, worked better shooting extreme angle around 52-55 degrees, giving it height and then a long slow descend.. I guess only way is by trial and error or any advice for arrows for this trajectory?

@kviljo Ай бұрын

Were you shooting with a lot of wind from behind? That will give you some advantage of aiming higher. I'm not sure what angles are optimal in what weather, but generally it is said that low angle is good for shooting against the wind, while higher is better when shooting with the wind.

Nice video! i wondering why not you full drawn your siper?

@kviljo 6 күн бұрын

@@TheAltair32 The point of the arrows should most likely be drawn to about the middle of the siper. However, these bows stack a lot, so generally we are able to draw an inch or so into it. That is, unless shooting lower weight bows, of course 😄
