Be cool to see 3 vs 4 fletch as well

This is great. So much different than all the other “fletching test” videos out there. I really like how this isn’t a “which one wins” test as all the vanes were similar. Very unbiased and technical way of doing this! Thank you!

My take away is that offset/helical has much more effect than the specific vane shape/design/material/brand.

This video is remarkable value to our archery community.

I think it would be interesting to see how 4 arrows fletched up with the same vanes at 4 different offsets preform. Might get an optimal stabilization at a specific offset angle. Thanks for taking your time and efforts to post your experiments and results.

This pretty much confirms a lot of what we already knew. I’m really interested to see surface area vs surface area, like a long low profile vs a short high profile with similar surface areas. Keep up the good work! I might build one of these wind tunnel for my own arrow builds.

Exceptional video, thank you for taking the time to do this.

The effort you have put into this is awesome. You’re obviously a smart fellow…. 😉👍

Filling the tube with a bunch of straws will dramatically reduce turbulence. It’s how we made wind tunnels in my mechanical engineering program. Interesting way to test vanes keep it up

Appreciate the time and effort you're putting into these videos.

Crazy cool and interesting. Can't wait to see more tests and results

Fascinating. Love you're work.

You son are definitely a force to our knowledge.

Science is awesome! Keep up the great work! Vanes are super cool!

Awesome video very cool test!!

Great video! Looking forward for more test! I very much appreciate your afford you put into this.

Interested to see some smaller vanes like the X3...very cool, appreciate the time you put into this!

Thanks for a proper test! It would be interesting to know how much it differs if you have a fourth vane and alter the degrees as well.

Hey Lucas, As someone working in the aerospace industry with experience in wind tunnel systems, I wanted to share some insights regarding your data on vane damping times. While your data shows that most vanes have similar "damping out times" in the 10-second range, this might not fully capture the differences between vanes due to the nature of exponential decay in damping. Exponential decay typically involves a steep initial decline followed by a gradual leveling off, never truly reaching zero. While many vanes may reach a steady state within the same 10-11 second window, focusing on the initial 0.5-1 second could reveal more significant differences. The steepness of the initial decline in the curve might better indicate the vane's efficiency in stabilizing the arrow quickly, which is crucial for optimal performance. By analyzing the first 0.5-1 second, you can better understand the immediate damping/restoring forces each vane exerts, offering a clearer picture of their performance. This approach can provide more granular data on how effectively each vane stabilizes the arrow, highlighting differences that the overall damping time might obscure.

Excited for more!

I absolutely love this video and info. But my only critique is, please speed up the video when looking at the longer timers

As always awesome video! Thank you. Can’t wait for the next one. You should test Aerovane as well. I’d also like to see different size shafts. Not enough time in the day I know. Thanks again, I really like what you are doing and appreciate it!

Great job 👏 very interesting and informative as usual.👍😊 keep up your great work!💪😁 God Bless you and your family 🙏😇❤️🇺🇸

This is awesome, very interesting! Thanks for doing this. I’d love to see how each of these vanes would stabilize with a max helical using the Arizona ez fletch

Quality content

You should try this test with Zinger Fletchings and see how they compare to vanes.

Thanks for sharing

Fill the wind tunnel full of straws, that should create laminar flow. Keep up the awesome content!

Keep it up!!

Other than testing different fletchings at different offsets, are you able to attach different broadheads to the front as well and test how different vanes stabilize different broadheads? Great video and has become one of my favorite series. Appreciate the time and effort!

Very interesting. Thank you for doing this. What I find most interesting is the similarity between vanes with similar offset / helical. What I'd be interested to see is same vanes with different offsets / helical. Perform this like a design of experiments (DOE).

Great work Lucas. Have you considered a terminal velocity wind tunnel blowing from underneath. You would need to be able to vary the tunnel airflow velocity. Should give an estimate of vane drag.

I’d be very interested to see if there is a difference at all from placing of the fletching. As far as stabilization time goes. For instance, I run all my vanes about an inch and a quarter from my nock to keep the pressure away from my face, and I’ve had a lot of guys tell me that my stability is gonna be a lot worse 🤷🏻‍♂️🤷🏻‍♂️ them arrows be shooting good

I don't know if you have a way of measuring, but it would be interesting to see the drag force applied. Especially when you get to testing different offsets, the related force during stabilization and after stabilization would be really cool to see!

Would be cool to see how fast all those vanes stabilize with the Arizona ez fletch full helical. Also what’s the wind speed?

Amazing video, you should also do one testing degrees of helical and see if the parachute effect really affects arrow flight

Great stuff! Feathers? ps: love hearing the kids!

That lil wobble after stabilizing could be due to some dyes are heavier than others so even the same vanes from manufacturers can vary in weight slightly color to color

Tacs have a stable quiet platform and instant recovery.

Would love to see some of the more unique and quick fletch options like FOB, zinger and easy vanes(Australian based company, I think NAP also has something out they call easy vane). Also interested in which vanes are less effected by crosswinds.

I bet if you fletch the blazers like the others it will perform the same. I’ve been shooting different size fletch through radar and all slow down around 30-31 fps at 80 yards. All arrows have been fletched with the same jig.

Nice test. It would be interesting to see how a 4 fletch compares to the 3 fletch in stabilization. I don't know if you would be able to test this, but stabilizing with a fixed blade broadhead would be very good data for hunters.

Awesome content Lucas! Love the engineering and analytical mindset that you bring to this testing! I would recommend for your imperfections you might be able to 3D print a hexagonal flow straightener on the forward side of the wind tunnel and have the air flow suck through that. The other takeaway that I would love to see is whether or not the same vein with different offsets or helicals make a difference in your stabilization time. Thanks for all the great content. Looking forward to the Android app

Nice to see 4 fletch test

I think your onto something here but none of it matters unless the arrows are spinning.

Great test. Are you going to do a same one with spin wings or similar?

Food for thought - The shorter the vane the total distance that a helical goes around the shaft is shorter. Logically, it makes sense to me that to get the same spin out of a 2" vane you need more helical than a 2.8". I like 1.5-2 degrees on a Max Stealth and more like 2.5-3d on a 2".

Can you please do a test of the Blazers fletched at the same 2.5 degree offset as the others?

Not that I know anything but if you made a tip where the arrow could spin with airflow it would be more realistic I would think

Absolutely love all your content firstly.... but wanted to ask if the test with the Balzer vanes is accurate if the offset is not the same as the other vanes? I would assume that the helical plays a big role in the performance of the shaft as a whole... a rotation shaft definitely stabilises faster

This is awesome. My only concern is that the airflow is going in the wrong direction across the arrow and vanes.

Please test Firenock Aerovane 2 & 3, and TAC.

center of pressure - center of gravity = rate of stabilization, so as you said if the surface area is the same, they will correct the same, altho there might be miniscule effects on airflow with different type of vane design, some introduce more drag due vortexies

I think there's two main flaws in the testing. 1) the arrows are not able to spin freely. 2) the wind force is pushing from the back of the fletchings as opposed to the front. I believe there's a reason for fletching taper and that is to increase surface area as wind passes from the front of the arrow (short end of the taper)

Nice! What’s the brand and model of the arrow scale you got there? The orange one. Keep up the good content 👍 thank you.

Hi Trevor's just want to share a thought with you about a stable air flow and how u can achieve that,I saw this done on a tube video,they got a lot of plastic drinking straws together and placed them in front of there fans,when the air was pushed through them with the fan then the flow was stabilised hope this may give u something to try.also it's cheep to do if it works for u.cheers Rene from Aus

Can you do severe 3 fletch helical vs 4 fletch with offset

is the wind coming from the bottom? if so i wonder if changing the direction the vanes are facing would change outcome.

Cool video - thank you. Any value in the spin rate speed vs time to stabilize or is it all about surface area?

Awesome stuff! I guess the short arrows make the arm roughly same as in an actual arrow, but does the fact that the test arrows are rotating radialy about the point and not about the C of G or C of L, whichever it is, have any effect?

I've always wondered if arrows from a traditional bow are slow (~150 fps) enough to experience linear drag, whereas I assume arrows from a compound are fast enough (~300 fps) to experience quadratic drag.

What are you using for a fan? Would a leaf blower give you more speed?

Test should have included FOBS

I wonder if suction from behind the arrow would be better than a blower from the front? Just thinking about the fan itself creating imperfect turbulence in the tunnel but suction from behind the arrow might create a more uniform airflow across the vanes?

Can I just ask, is your wind tunnel blowing air from the top or bottom? I can't tell from the video. The way the vanes are designed the wind should be blowing in from the top to play to their strengths, but I don't know if that's what's happening or not. Interesting video anyway.

I wonder how the Blazers would done had they had a decent offset?

Wind direction coming from behind the arrow or is the fan pulling air?

Great vid. It it tells me that my arrow would travel @ 200yds before complete stabilization😅

But typical arrow flight is under a second, maybe well under a second.

Question is fan blowing from bottom up or top down?

These are bolts for a crossbow not a standard bow, so it wasn't be accurate study for a arrow for a Bow

I own every vane you tested and in real life the DCA vanes stabilize arrows faster than any other vane. Sorry but this test proves nothing

Why are you so rude to your co-host?! Maybe I want to hear what she thinks... LOL I'm just playing.

Bout fell asleep.

test is relatively useless without the shaft flex induced by a bow
