Fascinating. Love you're work.

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

Tacs have a stable quiet platform and instant recovery.

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

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!

Very interesting…Is there a part 2?

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

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.

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

Be cool to see 3 vs 4 fletch as well

You ever try light weight spin wing 4 in vanes in your tests.? Tom Lund

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.

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

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

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

You son are definitely a force to our knowledge.

This video is remarkable value to our archery community.

Quality content

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?

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

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?

When we can expect android version?

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.

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

Oh boy I want see this video great idea

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.

Wow I love this.

Excited for more!

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).

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.

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.

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

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.

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".

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

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

Dude, we need you. Dont stop doing this kind of videos. I have suggested your videos on penetration more than anything else on the internet. Im so grateful man. Great job.

Keep it up!!

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

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

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

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

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

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

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

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)

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

Question is fan blowing from bottom up or top down?

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