The arrow’s fletchings steer the arrow towards the intended target, which is why arrows rotate in flight. Additionally, it is mainly to help in increasing speed and straightening the arrow’s course.
For people who don’t know much about archery, you may be thinking that arrows follow a straight line and launch forward. However, it is not the case in archery. It is more complicated than most people think.
The physics behind archery is more than just finding the right angle to shoot your arrows. Arrows, too, have a phenomenon behind how it moves before it reaches the target, which relates to the “archer’s paradox.”
The correct arrow length, proper fletching, and total weight influence how successfully you can hit your target. However, you must not forget that the archer’s paradox plays a pivotal role in helping you succeed.
The archer’s paradox happens when the moment you shoot the arrow, it follows a different trajectory than what you would expect.
For example, when you release your arrow to the right of a bow, it does not follow the desired course—instead, the arrow wobbles and spins in flight. Therefore, the archer’s paradox is the phenomenon that pertains to your arrow’s behavior while in the air.
If you look closely and observe the several videos showing the arrow’s flight, you may notice that the arrow bends and whips back and forth as it leaves the bow. It all happens the moment you shoot the arrow.
Halfway past the bow, an arrow’s string starts moving back in the opposite direction to where it was heading in the first place. In other words, it slides off the fingers and goes to the left first.
It will then return to its resting position by moving to the right. The arrow wobbles in both directions at this stage, but it hasn’t yet left the bowstring.
The arrow naturally wobbles the moment you shoot and completes its initial wobble as it entirely exits the bow. However, it has no assurance that this means a higher chance for you to hit your target.
If the arrow spine is too thick, it won’t wobble correctly and will likely miss its mark. On the contrary, it may swing too much and will not accurately fly if it is too thin.
Therefore, the fletchings will need the proper thickness of the arrow spine for it to catch the air and tug on the arrow.
The fletching serves its purpose by causing the arrow to spin in the opposite direction. Thus, if the arrow veers to the right, the fletching tugs it to the left and vice versa, resulting in a spinning arrow. It is trying to line the arrow up before reaching the target.
A spinning arrow creates a force that counteracts the power trying to pull it away from its target. As the arrow reaches its target, it spins to accelerate the speed and straighten it.
Thus, arrows spin in flight to help you reach your target correctly.
How fast does an arrow spin in flight?
The arrow’s size, length, and fletchings affect how quickly the arrow will turn and travel in the air. There is no fixed estimation of how fast an arrow spins in flight. Instead, you can use an arrow rotation calculator to accurately measure how fast your arrow turns.
Upon releasing the arrow, it starts wobbling at first before it spins. Knowing the process of how arrows rotate in flight makes you curious about how fast they turn. However, it can be challenging to find out how accurately fast arrows spin.
It is easier to know how fast an arrow can travel than to determine the general estimates of how quickly an arrow spins in flight.
There is no available answer, yet there are factors that will help you determine to get a glimpse of how fast arrows can spin. Below are the several factors to keep in mind that influence how quickly the arrow turns:
- Arrow size
- Arrow length
The arrow size pertains to its weight and diameter. In calculating the arrow rotation, you need to know the arrow size to arrive at an accurate answer.
The problem is that not all arrows have similar sizes. Your arrows may not have the same size as the others and vice versa. Others make their arrows based on how they see fit.
As a result, it isn’t easy to compare them in general.
Another one to keep in mind is the arrow length which comes in two sizes: long and short.
Longer arrows spin more quickly than shorter arrows. It takes longer for longer arrows to straighten out. Since arrows spin to straighten out the arrows, longer arrows will rotate for a more extended period and faster than their counterparts.
Moreover, longer arrows have a higher chance of spinning out of control.
In contrast, shorter arrows straighten quicker and only take a little while to spin due to their lower surface area.
The design of the fletching affects how fast the arrow spins. There are two designs: twist and straight.
A twisted fletching design creates more rotation to keep the arrows straight. On the other hand, a straight fletching design doesn’t add any spin.
Therefore, there is a higher chance that the arrow with a twisted fletching design spins faster since it adds more spin to keep the arrow straightened out.
Nevertheless, besides mere assumptions based on the influential factors, it is better to use an arrow rotation calculator for a more accurate answer on how fast your arrow spin in flight.
Is a spinning arrow more accurate?
A spinning arrow’s primary purpose is to straighten out the arrow and increase the speed to hit the target successfully. Although it helps preserve the accuracy, it does not add more precision to your shoot.
There are a lot of elements that add or lessen accuracy to your shoot. Sadly, a spinning arrow is not one of them.
To understand why they spin, one must know what causes them to turn. The phenomenon serves its purpose of straightening the arrow and increasing its speed.
Instead of adding more accuracy to your shots, it preserves the accuracy. The angle, skill, and proper materials you used directly affect it. Hence, you can add more accuracy before shooting your arrow rather than influencing it midway.
Keep in mind that once you let go of your arrow, you can not stop or influence its direction. You won’t even be able to notice how fast or which way it spins since arrows can travel as quickly as 225 feet per second or more.
Therefore, it all depends on the preparations made beforehand, so there is a need for you to do an arrow spin test.
When your arrow spins well, then there is a chance that it may preserve the accuracy of your shoot.
What should I look for when spinning arrows?
Make sure your arrow is straight and balanced before shooting them by doing a spin test. You can do a spin test with or without using an arrow spinner.
One of the most overlooked procedures in shooting and tuning is taking a spin test of the arrows. Others fail to see the importance of using a balanced and straight arrow. This failure leads to the arrow not spinning well, and when this happens, the probability of hitting the mark decreases.
Some archers do not realize that once they send the arrow flying, they can no longer do anything, and all that’s left is to leave it to fate as you watch it travel in the air. Therefore, the need for spin testing the arrows comes into place.
Spin testing the arrows before shooting them aids in giving certainty that the arrows will spin well and the accuracy put will be preserved.
You don’t necessarily need to spend bucks purchasing an arrow spinner to do spin testing. If you have one available with you, then better.
You can do a spin test on a hard flat surface for those who do not own an arrow spinner. A glass table is an excellent example of a hard flat surface for an arrow spin test.
You can watch for wobbling as you roll the arrow across the surface in this method.
Meanwhile, you can do a spin test for those who opt for arrow spinners by putting the arrow on the spinner and then rolling it with your palm.
If you notice any wobbling, the following are the procedures you can try to correct it:
- Remove the broadhead, head the insert, and thread on the broadhead again if the arrow appears to wobble where the broadhead meets the shaft.
- Sometimes, the imperfection lies in the insert and not in the arrow. An improperly glued insert makes the arrow wobble. The shaft may be bent or an incorrectly glued insert if it continues to rock.
You can solve this by making sure that the tip of your arrow is square before you glue the insert once again.
- If the arrow wobbles on the nock side, realign the nock and check if there is no excess glue around the fletching that causes the arrow to be out of balance.
After trying the procedures above, try spinning the arrow again to double-check for errors. Once the arrow is straight and balanced, you can now use it for shooting.
Do you need an arrow spinner?
You don’t necessarily need an arrow spinner to spin test the arrows. However, using an arrow spinner helps you to precisely check for errors on your arrow that could potentially ruin your shot.
As you try to look for errors on your arrow before shooting, you may wonder if there is a need to purchase an arrow spinner or opt for the manual method.
Every person has their own opinion on what works well for them. Some archers recommend using an arrow spinner for the arrow spin test. Meanwhile, some recommend using the manual method instead, so you don’t need to waste your money on a tool.
To help you decide, below are the advantages of purchasing an arrow spinner:
- Made for testing arrows
- Gluing outserts, inserts, and nocks
Compared to other archery tools, arrow spinners are relatively inexpensive. Checking your arrow does not have to cost you anything.
An arrow spinner helps you thoroughly check your arrow’s straightness, nock alignment, broadhead balance, vane, and feather balance. Using an arrow spinner, you can comfortably fit your arrow with more precision than the manual method.
It can also aid you in detecting even the slightest bend in the arrows.
The arrow spinner’s precision aids in ensuring a preserved accurate and smooth arrow flight.
The Arrow spinner is a device designed to test arrows. You can rest assured that the tool serves its purpose.
The arrow spinner is essential when gluing outserts, inserts, and nocks if you have carbon fiber arrows. Remember that an improperly glued arrow destroys its balance and flight accuracy.
Although it has numerous advantages, it also has some disadvantages that led some archers to use the manual method for spin testing:
- Waste of money
- Your palm or a hard flat surface will do
Although an arrow spinner is inexpensive, it may still cost you a few bucks. Instead of wasting your money on something that you can do manually, the arrow spinner tool is not necessarily a need.
Some archers can quickly tell the errors on the arrow by simply spinning it in their palm or on a hard flat surface. If you can easily spot the mistakes without needing an arrow spinner, the manual method will work well.
Therefore, an arrow spinner is not a necessity. However, if you want a more precise spin test on the arrows, purchasing an arrow spinner is worth it and helpful.
Arrows spin in flight when there is a need to straighten the arrow up as it nears the target and preserves the accuracy of your shoot. Moreover, spin testing the arrows prevents further errors that may hinder you from hitting the mark bullseye.
