Aerovanes are the first ever vane that employs airfoils on an arrow. Unlike traditional vanes, the Aerovane is not flat, and must be fletched straight to function properly.
Instead of using drag, the Aerovane uses an airfoil to create spin. Bernoulli's principle, a fundamental law of fluids in motion, states that when flow speed increases, pressure decreases and vice versa. Just like an airplane wing is designed so that air will flow more rapidly over the upper surface than the lower one, decreasing the pressure on the top surface and increasing the pressure on the bottom surface. This difference in pressure provides the lift that keeps the airplane in flight. In case of Aerovanes, as there are multiple vanes on a shaft, circular lift occurs, causing the arrow to spin.
There are 3 main contributing factors that make Aerovanes quiet:
Very rigid airfoil: by having a rigid airfoil, a lot of wow and flutter (also know as harmonics) are minimized. Aerovanes are not only one of the hardest vanes on the market it also employs the design of an ultra slim pyramid which is one of the most rigid structures based on volume.
Very round leading edge: just like an owl's wing. This round leading edge allows air to flow over it while creating minimum air molecule to air molecule disturbance. This also minimizes the formation of a delta vortex, which robs speed and creates sound. To further reduce sound, all edges of Aerovanes are round.
Micro texturing: in case of Aerovane Ir1 and II, 5 and 3 zones respectively of micro-texturing is applied on different areas of the surfaces of the vane to get the least amount of back end turbulence to minimize the vacuum back pressure (bubble). This micro texturing also helps to generate a different level of micro turbulence to minimize surface to air drag.
If you follow the information presented in the above FAQs concerning installation and tuning, Aerovane I and/or II could tighten your groups and increase your effective range. The use of Aerovane will not turn an average archer into a tournament archer over night, but they will provide more consistent flight. Thus, allowing the average archer the ability to tune their specific set-up for a possible increase in accuracy.
Since Aerovanes are based on airfoil technology, it is essential that it is as rigid as possible to generate as much lift as the material science allows. If safety were not an issue, the Aerovane would be made out of metal to fully utilize the airfoil.
The Aerovane is made of very stiff plastic no doubt. Like all high durometer plastic, low temperatures will make it very brittle. When the temperature reaches around -10F, any in flight contact will the Aerovane will lead to shattering of the vane. As long as it does not make contact in mid air, the Aerovane will not crack or tear even at much lower temperatures.
Most metal straight clamp type jig would be useable to fletch the Aerovane. Please note that although the Arizona Easy Fletch straight clamp claims to be straight, it is actually a 1 degree offset, thus not suitable for fletching Aerovane.
Aerovanes are injection molded, thus it may have some mould oil on it. Although the factury may have cleaned teh vane with soap and water, it is always advised to clean the gluing surface and the feet of the vane with 91% alcohol (denature alcohol is not as ideal as 91% alcohol has 9% water and water is better to disolve the possible soap residual that may be left after the washing process of the vane) to ensure perfect adhesion. For even better results, one can submerge the entire vane in 91% alcohol for about 5 minutes, let it air dry and ALL gluing surface will be prfectly clean for glues.
Aerovanes are based on airfoil design, and the design copies the profile of the frontal portion of an owl's wing. With this design, the vane is no longer flat which makes a standard straight clamp close to impossible to clamp it straight. To overcome this design difficulty, our Patent Pending wind channel solves the problem by utilizing the 1/16" square brass bar as a spacer inside the wind channel. The thickness of the bar will allow the clamp to clamp the fletching straight at its feet on both sides. In other words, if you want to fletch Aerovanes correctly, it is essential to use the Aerovane tool on the clamp as indicated in the manual.
Based on the field reports, Aerovanes seem to work best under 1" (<25mm) from the center of the nock to the end of the vane. Although Aerovanes do not create turbulence by itself, the combination of the vanes in a vertical lift does. Therefore it is best to leave less than an inch from the nock point to the vane for best performance.
Traditional vanes or feathers are usually flat in design. In order for them to spin in the air, helical fletching, angle fletching or adding a flipper (rudder) is a must to create drag which causes the arrow to spin. The Aerovane spins based on Bernoulli's principal, the utilization of airfoil, which creates lift based on a variation of airflow speed on the 2 sides of the vane. By utilizing multiple vanes, the multi directional lift will create spin.
Aerovane's inception was to make a vane that is quiet and able to spin. After some research it was found that the profile of an owl's wing was what is needed. As a deeper understanding of how an airfoil on the Aerovane works, and the market demand for a lighter and shorter profile vane for high-speed bows, Aerovane II was born. About the first week of July 2009, all Aerovane I were technically sold out and the mould to make it is also mould out. Firenock are now offering Aerovane Ir1 which replace Aerovane I. This vane have all the features of Aerovane II and also have the most aggressive air scoop. The main application approach of Aerovane I and II is that Aerovane II is more suitable for speed over 295FPS while Aerovane Ir1 flys well even as low as 160FPS.
The Aerovane I is designed to be a very forgiving vane and a direct replacement for the common high-speed vane like the Blazer™. Aerovane II is a combined design where the delta wing is part of the airfoil. The Aerovane II also has micro texturing to further improve on air drag efficiency. The Aerovane II is meant to be shot with bows at over 300 FPS while the Aerovane I will work with arrows at much lower speeds while still having most of the benefits of the airfoil design.
The Aerovane Ir1 come in 4 colors: white, red, green and lime.
The Aerovane II is currently available in 10 colors: white, red, orange, green, pink, black, clear, yellow, lime, and blue.

Aerovane Ir1 is currently only available in an 18 pack for $10.95, but we do plan to offer a 100 pack and 1,000 pack in the near future.
Aerovane II is currently available in an 18 pack and 100 pack for $10.95 and $50.00 respectively, we do plan to offer 1,000 pack in the near future
The Aerovane Ir1 is actually a more advance design than Aerovane II. Aerovane II single airfoil is doing the steering and cause rotation at the same time. With more understanding of Airfoil design, it is now understood that at lower air speed, the 2nd air foil of Aerovane I design is what make it able to fly even at speed as low as 160FPS. Like a glider have more wind surface while a jet plane do not need as speed is what it has to offset the limitation of small airfoil's lift.
Aerovane Ir1, and II is not just rough on the surface. There are actually 4 and 6 different textures on the Aerovane Ir1 and II respectively to get the maximum benefit of the airfoil. The front portion of the vane where the airfoil is the roughness if 0.0402 mm, the trailing end of the airfoil is 0.0201mm, the back of the vane is 0.0150mm while the concave surface is polished to 0.000,001mm. To read more about why and how the roughness makes Aerovane II so efficient, read more about it at Technical Aspects of Aerovane Ir1 and Aerovane II.
The Aerovane I is a smooth design, which means it does not have any micro texturing on it. When an arrow passes through an animal with an Aerovane I, the chance that the surface will get scratched is very high. The scratch, which behaves like micro texturing will now form micro turbulence, which actually increase the aerodynamic performance of the vane. This performance gain is also due to a reduction of the vacuum bubble just behind the airfoil which actually increases lift and air speed. Therefore it is not hard to see why the arrow now makes big circles instead of shooting straight!
There are 2 ways to solve this problem. One is to strip the scratched vane and glue on a new one so all three vanes are now smooth. The other method is to use 80 grit sand paper and scratch up the other 2 vanes. Both approach's have the same results, the same aerodynamic characteristics on all three vanes. The funny thin is that the scratched up vane will actually fly flatter as it has more lift and less drag due to the micro turbulence it now generates from the scratched up surfaces.
As of early July 2009, Aerovane I is replace with Aerovane Ir1 which has 6 different zones of micro texturing, this is no longer an issue anymore.
Low speed characteristic of Aerovane Ir1 is different than Aerovane I. Aerovane Ir1 even with the improved air scope did not do well slower speed with straight fletch. More testing led to some extremely interesting findings. Speed is the only thing that matters with Aerovane when fletch straight!
For speed below 295fps even with the most aggressive air scope that I have ever designed, Aerovane Ir1 did not do much below 275fps compare to other vanes in the market. With just 1 degree helical the spin rate jumped from 9 rps to 37 rps. That is close to 400% increase! As my wheel in my brain turn, I say what the heck and used the helical clamp on the Aerovane Ir1 on the straight set up Bitzenburger without the brass tool. What I need to do is to file off about 1.5 mm off the tip of the clamp on the bottom so I can maintain constant contact with the arrow without moving the jig (which is set up for straight with the 1/16 square brass Aerovane Tool installed).
The result is little more than spectacular. The arrow seems to fly like a dart even at low speed. I then proceed to use Arizona Easy Fletch on Aerovane Ir1. Remember we are talking about low speed here, 275 fps or lower. Aerovane Ir1 "seems" to fly better with an offset or helical than expected compare to straight. The explanation is quite simple: at low speed, the Bernoulli's Principle do not work very well, thus lift is a lesser effect. Also at lower speed; drag is not a significant factor; but it is a real factor on causing the arrow to rotate.
Therefore, one should treat Aerovane Ir1 like any other vanes and need no special tools and you gain quiet flight and accuracy.
Aerovane Ir1 test result by Jeff Bailey
During the week of 03 May 2010, Dorge Huang (Operating Manager of Firenock, LLC) and I were discussing the effect of a helical on the Aerovane 1 revision 1 (1r1) vanes. After reviewing the data from Gary of Mathews, few ideas surfaced, but decided to put the arrows to the test, just to be sure. The requirement was to shoot arrows fletched with Aerovane 1r1 on a helical at speeds less than 280 feet per second (fps). The equipment I used for this test was the Mathews Z7 set at 68 pounds with a 29 inch draw, Victory HV V1 350 arrows (with weight tubes), Firenock lighted nocks, QAD Pro rest, Sword sight, and a Scott Sabertooth release.
Since my normal set up produces speeds over 300 fps, I know I needed to add weight to slow down the arrow. I chose a 2 grains per inch (gpi) weight tube and a 3 gpi weight tube to add weight without effecting the spine. I also used a Right Wing Bitzenberger clamp on their straight jig to give me a 1 – 1.5 degree helical. The result of the weight tubes are as follows: The 2 gpi tube gave me an average arrow weight of 425 grains with a speed of 278, and a Front of Center at 6.9%. The 3 gpi tube gave me an average arrow weight of 455 with a speed of 268, and a Front of Center at 6.47%. At this point, all arrows were tipped with a 100 grain field point.
The test consisted of shooting two arrows (one set with the 2 gpi tube and one set with the 3 gpi tube) at varying distances between 20 and 60 yards, then measure the distance between the two sets of arrows. The 2 gpi tube arrows flew remarkably well. In fact, no matter which target the arrows were shot at, they always ended up touching each other. The 3 gpi tube arrows were a different story. Up to 30 yards, the two arrows were within 1 inch of each other. After 30 yards, the two arrows started going their separate ways, with the largest distance of 4.5 inches at the 60 yard target.
By using the Firenock lighted nock, I was able to see the arrows as they were going towards the target. It appeared the 3 gpi tube arrows were going in level (especially at longer distances), instead of a tip down entrance. I discussed the results with Dorge and we concluded increasing the Front of Center on the 3 gpi tube arrows could increase the accuracy. Therefore, I changed the 100 grain tip with a 125 grain fieldpoint on the 3 gpi tube arrows; which produced a new Front of Center of 9.05%. I did not want to add too much weight at the tip knowing this will end up weakening the spine of the arrow. The end result was the two 3 gpi tube arrows grouped within one inch of each other all the way out to 50 yards, then the gap only increased to 2 inches at 60 yards. There was now a definite tip down entrance at the 60 yard target.
In summary, placing a 1-1.5 degree helical on the Aerovane 1r1 vane can produce very accurate results. In addition, increasing the Front of Center as arrow speeds decrease can only add to the accuracy.
To correctly set up Aerovanes, a straight jig with the ability to mount the 1/16" square bar is technically a must. Just like any other vanes, basic cleaning and care is all that is needed to successful fletch the Aerovane beside the modified straight clamp as mentioned above!
We have learned how the Aerovane affects the wind around it. A term called "Cross Wind Signature, CWS" is introduced to make it easier to describe what is actually happening. In reference to the Duravane 4" long vane with a 2 degree helical fletch shooting out of a 295 FPS bow, it was observed that no less than 10" of air was disturbed when the arrow passed through the still air. This column of air being disturbed is what is called the "Cross Wind Signature". Many vanes in the market have even bigger CWS, which is not the case with Aerovanes. As the Aerovane use's airfoil technology instead of drag, the vane is disturbing a minimum amount of air when the arrow passes through. As the air column decreases in size, so does the CWS. The smaller the CWS, the smaller the effect of crosswind, thus Aerovanes are less affected by crosswind.
Aerovane I is 11.3 grains in weight +/- 0.2 grains
Aerovane I is 0.557" (14.14mm) high and 3.69" (93.77mm) long
Aerovane 1r1 is 9.0 grains in weight +/- 0.05 grains
Aerovane 1r1 is 0.512" (13mm) high and 3.54" (90mm) long
Aerovane II is 6.48 grains in weight +/- 0.02 grains
Aerovane II is 0.55"(14mm) high and 1.967" (50mm) long
The Aerovane I is a very forgiving vane. One does not need to change the spine or arrow length to use the vane.
The Aerovane II is a very high performance vane. In some cases due to the inability for the bow to be tuned, one can use the arrow length and spine to fine-tune the bow. Very much like the traditional finger shooter with a longbow. It is advised that one can use an arrow with a full spine size lower in an Aerovane II application and up to 3 inches longer to make fine tuning possible.
The Aerovane I will work with nearly any arrow rest, as it is a very forgiving vane. Any drop away rest, or containment rest will work. That being said, in reference to a Whisker Biscuit, it is proven that when a brand new WB rest is used, the performance of the arrow suffers due to the thickness of the airfoil. This is not the case of a close to worn out Whisker Biscuit as there are "shot out" groves on it which actually make it ideal for Aerovanes.
With the Aerovane II, nearly all arrow rests, besides a brand new Whisker Biscuit will work. In the case of some binary cam bows, people had much better luck with an arrow rest like the Hostage and QuickTune if they are not great bow tuners. If a bow is micro tuned properly, any rest besides the WB will work very well with the Aerovane II.
The Aerovane I will work with any bow in the market as it is a very forgiving vane. Since it is a rigid vane with no give, a bow that does not allow for a clear arrow path will not work. e.g. traditional archery like long bow that shot out of the shelf will not function well with Aerovanes.
The Aerovane II, is as a high performance vane that will create some serious spin. Any deviation on the launch cycle (nock travel) will show. That is why the Aerovane II is easier to shoot out of bow that can be micro tuned by means of a cable guard from center shot distance and yolk cable adjustment. In the case of a binary cam bow with fixed cable guards or rollers, it is a lot more involved to get the bow tuned with the Aerovane II. That being said, we do find by utilizing a full containment rest like the Hostage™ and Quicktune™ 360, the Aerovane II can be shot out of binary cam bows with an easier set up process.
The 09 Dream Season is a great bow that can be shot with either a full capture or drop away rest. Since the nock travel on this bow is not level, the full capture rest is the easiest and quickest way to tune the bow. If you choose to go with a full capture type rest, either the NAP Quicktune 360 or Octane Pro Hostage will work fine. Set up the rest based on the centerline markings of your bow and you will be very close to shooting a bullet hole through paper. Some minor adjustments will probably be necessary.
If you choose to go with a drop away rest; which is my preference, you will have to make several adjustments to get your bow in tune. These adjustments are as follows:
D-Loop/Nock location: In order to counter the nock travel, you will need to have a high nocking point of at least 3/8". To give you an idea of the distance I am talking about, the distance from the center of the string suppressor to the center of my D-Loop is 6 3/8".
Cable Guard: You will need to move your cable guard as close to your rest as possible without causing any interference, this will help to line up your string, arrow and rest when the bow is in the drawn position. You do not have to move the cable guard very much, I only moved mine approximately 1/8". Keep in mind, when you look at the bow from the back with an arrow on the string, it will look like the arrow will strike the cables; however, due to the nock travel it will actually miss them. You will be able to adjust this through further paper tuning.
Left Yoke: In order to bring your arrow back towards center line, you will need to put twists into the left yoke tightening the string. Start out with six twists, you can always add more if needed. I ended up putting nine twists on my bow. To give you an idea of what to look for once you twist the left yoke, when you are looking at the top cam from the back of the bow, follow the string down from the top of the cam to the bottom. At the bottom of the cam, it will appear as if the right edge of the cam and half of the string (on the cam itself) are to the right of your main string. Keep in mind, after you twist the left yoke, you will have to adjust the cams to get them back into timing the best you can. I was able to get my bottom cam timing mark to lay perfectly center on the cable; however, the upper cam timing mark lays on the front part of the cable. This did not seem to effect the performance of the bow.
You will have to play around with #2 and #3 above to get the right combination of adjustments for your bow. It may sound like a lot to do, but it is well worth the time and effort in the end. Just to give you an idea of how well the above steps will tune your bow, after I completed these steps, I was able to shoot a field point and a fixed blade broadhead into the same spot out to 50 yards.(written by Jeffery Bailey)
With a 65lb bow, the 400 spine arrows react as if they are slightly weak in spine (hit to the right); 350 spine arrows react as if they are slightly stiff (hit to the left); and 300 spine arrows react as if they are stiff with a field point and weak with a broadhead. The simple solution to correct the 350 spine arrows would be to move the arrow rest closer to the bow (ie: more in line with the center of the bow). For the 300 spine arrows, the field report suggested the solution would be to increase draw weight from 65 lbs to 67 lbs or even 68 lbs; which would help to even out the results.
Both, Aerovanes are great for both target and broadhead flight. The inherited high spin design of Aerovanes would easily stabilize a broadhead tipped arrow faster than traditional vanes & feathers.
No turkey broadhead that is NOT mechanical will work with Aerovanes. Aerovane make such a high speed spin it will make a BIG turkey broadhead like the Gobbler Guillotine™ and the Magnus Bull-head behave more like a helicopter when shot. If one decides to use Aerovane equipped arrows for turkeys, the American Turkey Terror, Rage (with Gator rubber-band), and the Trophy Ridge Turkey Tom-O-Hawk are the few that will work well with the Aerovane.
With the turkey broadhead, both Aerovanes spins way too much for the big turkey broadhead to fly true.
With theAerovane I: It is really a personal preference as it is a very forgiving vane. One can choose from the big Magnum fixed blade broadheads to an expandable broadhead. As long as the bow is tuned well, the arrow will fly the broadhead well with the Aerovane I.
With theAerovane Ir1: It is the most aggressive aerodynamic profile of all Aerovanes today. Its ultra high circular lift capability requires broad heads that can handle high spin rates. The following spreadsheet showing the broadhead testing results from a slower bow. The bow set up is as follows:
Bow: old PSE compound set at 54 lbs
Arrow: Easton Axis 400, cut to 29.5"
Rest: Trophy Taker
Release: Pro Diamond
Target: Block set at 30 yards
The few shots using the Aerovane 1r1 were with field points to ensure the sights were accurate for the set up. Needless to say, every shot with a field tip went straight into the bullseye. After using a chronograph, it was found the average speed was 213 fps; along with an average arrow weight of 415 grains, thus equating to a Kinetic Energy of 41.8. After reviewing the test results, it is easy to notice a speed of 213 along with a heavy arrow would easily drop the arrow at longer ranges. The rotational force on the arrow produced by Aerovane 1r1 is not enough to overcome the heavy weight of the arrow itself. Overall, this was a very good test to show the effects of the vane on a heavy slow moving arrow.
With theAerovane II: We recommend fixed blade broadheads in most cases. As big as 1 1/2 inch cut fixed blades. One must however take into consideration the ultra spin rate of the Aerovane II, and look at the cross section of the broadhead. The more it pushes air, the worst it will fly. Some of the expandable broadheads may not work well with the Aerovane II, because the vane spins the arrow so much it can deploy the blades in flight. All truly secure expandable blade broadheads are good with Aerovane II.
Below is a list of the broadheads that we have tried with Aerovane out of bows at 320+ FPS and their respective flight accuracy. During this test, we shot two arrows with the specific broadhead at a 30 yard target for accuracy and grouping. Poor results are defined if both arrows hit at least 4 inches away from the bullseye at 30 yards. Good results are defined by at least one of the two arrows hitting the bullseye at the 30 yard target; while the second arrow will hit within a 4 inch circle from the bullseye. Best results are defined by both arrows hitting the bullseye at the 30 yard target. The tests were carried one step further and shot the Best results arrows at a 40 yard and 50 yard target. Both arrows with the Rocky Mountain Blitz hit the bullseye at 40 yards; whereas one arrow hit the bullseye at 50 yards and the second arrow was just outside of the bullseye (archer error). It is very obvious to us that speed and rotation plays a huge factor when shooting broadheads. Poor Results

More detail testing were done to see which broadhead was best in longer distance with Aerovane II which has much higher rotation rate than Aerovane Ir1.
These broadheads included Smoke Ramcat, NAP Nightmare, Rocky Mountain Blitz (Right Offset) and Rocky Mountain Blitz (Left Offset). The basis of the testing was to shoot two of the above listed broadheads to a Block Target 30 yards away. If both arrows hit the center bullseye, the broadhead is classified as "Best"; if one arrow hits the bullseye and the second hits within 4 inches of the center, the broadhead is classified as "Good"; if both arrows hit greater than 4 inches from the center, the broadhead is classified as "Poor." For all arrow / broadhead combinations that are classified as "Best". The tests were repeated as above shooting at a 40 yard and 50 yard target. Prior to shooting the broadheads, the bow was ensured proper set up by shooting through paper at 3 feet, 9 feet and 15 feet with a complete bullet hole. The bow that was used for this test is the Darton Pro 3500S set at 65 pounds at 29" draw with 29 inch Victory Archery VForce HV V1 350 arrows fletched with Aerovane II and Firenock practice nocks.
30 Yard Target Results
Smoke Ramcat - Best
NAP Nightmare - Best
RM Blitz (Right Offset) - Best
RM Blitz (Left Offset) - Best
40 Yard Target Results
Smoke Ramcat - Both arrows hit the bullseye
NAP Nightmare - Both arrows hit the bullseye
RM Blitz (Right Offset) - 1 arrow hit low 1"; 1 arrow hit left of the bullseye 1"
RM Blitz (Left Offset) - Both arrows hit the bullseye
50 Yard Target Results
Smoke Ramcat - 1 arrow hit the bullseye; 1 arrow hit left of the bullseye 1.5 "
NAP Nightmare - Both arrows hit left of the bullseye 2"
RM Blitz (Right Offset) - 1 arrow hit below the bullseye 1"; 1 arrow hit left of the bullseye 4"
RM Blitz (Left Offset) - Both arrows hit left of the bullseye by 2.5"
In summary, the Smoke Ramcat appears to match the spinning effect (or rotational force) placed on the arrow by Aerovane II becoming a very accurate arrow / broadhead combination especially at longer ranges.
The Aerovane I being a very forgiving vane really does not have a best speed. However, we do believe that at below 200 FPS it is no different in performance than any 4-inch vane. Form the limited field data, the Aerovane Ir1 seems to fly well even the speed as low as 160 FPS.
The Aerovane II being a high performance vane needs speed to show its potential. We believe, to achieve optimum performance 295 FPS is where it really shines. However both Aerovanes will work well with lower launching speed arrows. Even at slower speeds one should still be able to enjoy tighter groups and silent arrow flight, as they are the original design goals.
Just like the Aerovane II which was shortly released after we introduced the Aerovane I in September 2008. The more we understand, the better the design can get. The field data is pouring in daily and this leads to a deeper understanding. The Aerovane is a continuous learning project both in design and theory. You can be most assured that newer designs are being worked on at this time. Firenocks has released Aerovane Ir1 on July 10th 2009, and we shall release more information when it is closer to a release date on the latest and even more higher performance Aerovane(s).
Both the Aerovane I and II are designed to take the most advantage of aerodynamics as the arrow passes through air. There is no gain in speed when launched from a bow. Aerovanes are about how long and flat one can shoot an arrow via the advancement in hang time provided by the means of airfoil and lower air drag. One however will notice a significant gain in speed as the shooting distance increases comparing with other vanes due to a reduction in drag compare to the common vane on the market.
If your bow shoots 330 FPS, you can typically expect the following:
Aerovane I : 0 to 30 yards out of your 1st pin
Aerovane Ir1 : 0 to 36 yards out of your 1st pin
Aerovane II : 0 to 40 yards out of your 1st pin
For Aerovane I, it really does not have an ideal speed, as it is a very forgiving vane. Aerovane II, on the other hand being a high performance does enjoy the benefit more with today's faster bow. Base on the current field test data, 295 to 305 FPS seems to be a good launching speed for Aerovane II to achieve the maximum potential.
[01] What makes the Aerovane so unique?
