I tend to visit your channel when I have a doubt studying Aerodynamics for my ATPL, they are so good to get the basic concepts, such a pity that you passed away. Thanks for everything Sam!!! Fly high!
I just found this channel. I just started ground school. I was about to post that this is the best video I've seen on adverse yaw and it helped me understand it the best out of all the videos and books I've read. Thank you Sam and RIP sir.
You wrote, "educational videos take so much effort..." You're the new "best friend" of technical writers everywhere for pointing this out to people. Breaking things down into the absolute minimal and simplest of concepts is an underappreciated art form. If you do it right, it LOOKS easy, but is actually a lot of work. You did it marvelously, by the way.
Nice. Clear and thorough, but also watchable. Peppy pace, good lighting, attractive visuals, clear oral track with no self-indulgent thinking out loud. Well done.
I just started flying lessons (after ground school) and while this seemed to make sense, it didn't really. I watched a few other videos on this topic, but I wasn't quite there. Watching this video it's like a light bulb went on in my head, and I totally get it now. Thanks so much - can't wait to watch more of your videos. You'll make a great CFI, if you are not already.
I honestly don't know anything about airplanes nor aerodynamics but I can confidently say that your videos are very well done and I'm always looking forward to your producing more. Please continue to make videos, they are awesome
I am excited to see how you explain this. Adverse yaw is a fun concept to ask young student pilots. When they can explain it, you know they are understanding aerodynamics.
Nice video. I believe the main purpose of the frize ailerons is to assist the pilot by reducing the effort needed on the yoke and that its effects on adverse yaw aren't that important.
+Samm Sheperd (SNRS) To be more correct on why it is worse for glider, here is a further reply. The due to the wings being longer, while in a turn, the outside wing is traveling faster than the inside wing. (This is true for any airplane, however the long the wing the greater the effect.) The extra speed equivalates to extra drag causing the outside wing to be pushed backwards just by the ram air. Also, gliders cruise at a much slower airspeed than powered planes (well... the J3 Piper cub may be an exception). Just think, how much rudder authority do you have during slow flight? And you have a much bigger rudder than gliders do. So the mix of small vertical stabilizers, plus slower airspeeds call for more dancing with your feet while flying. Hope that kind of helps. I love talking about gliding and the aerodynamics that go into play. I am sure the views here would love to know how a glider can stay in the air with no engine.
K0S0s I love gliders! Most people assume they just take a while to come down and have no idea about all the lift out there. The long endurance, cross country and even high altitude records set by gliders is incredible. And I'm sure the joy of a quiet bubble cockpit is just unbeatable.
Very clear and instructive video, thank you! This was very enlightening. I have noticed that I need to input some rudder to make my RC planes "turn nicely", and now I understand why :-)
Good video.. On an aircraft with power the adverse yaw is not to much of a worry, this is why the pilot can sit back and fly with just his rudder,, Now on gliders with long long wings and no engine to pull the craft around,,, Well this is why glider pilots have to coordinate ruder and ailerons and Elevator all at once.. Cheers Pete
+pepersorte yea using this airplane was a bit cheating haha. Short wings, differential ailerons, high speed. You glider pilots are the real stick and rudder users
cant wait to see more of your custom plane! I am going to build one too! Btw, I extremely admire your prowess in applying physics to your videos. Especially the part where you specificcally picked an airfoil for a certain speed, etc. Good work. I am a huge fan!
What a superb video! Bravo! My father in law would have liked you. He worked for Boeing during Ww Ii and McDonell Douglas. You grasp aerodynamics very well.
Great video. My instructor asked me to lookup what adverse yaw is, at the time I had a faint idea of what it was, now I know for sure and what causes it. Thanks!
Great video, so it seems programming some differential ailerons based on yaw gyro input could fix adverse yaw on the flying wing ? Try putting an array of those 1$ bmp180 sensors on your wing to detect boundary layer separation ! When I was in school we made wing surfaces out of straight fiberglass cloth sandwhiched between two shaped metal plates, it was light and very strong. Once you have the mold it was also very efficient in term of man hours to produce a wing section. Are you going to put a little encoder wheel on your AoA sensor ? These guys made one like this but I think their encoder is too expensive (more than 70$usd, but great accuracy, maybe too great) I think it might be possible to embed an accelerometer in AoA vane and just get differential reading with the airframe accelerometer to determine. That should be cheap, lightweight and accurate. Just need to find a tiny slipring that allows for a I2C or SPI signal, maybe something like that use in those 3 axis gimbal with the hollow shafts. How long did it take to print that wing, it looks huge ! What printer type ? Did you see those CNC foam cutter, seems to be very cheap to make with 8mm rods, SC8UU bearings and 8mm leadscrews ! ruclips.net/video/yKpq9FZMPqQ/видео.html Do you have a source for cheap expanded polypropylene foam in the US or CA ? Did you try to make autonomous gps guided UAVs ? I found a technique called RTK GPS that should delivery 2cm positionning accuracy (RTKLIB + ublox NEO-M8N).
I build planes in video games and was confused why planes need a rudder at all since I can do everything I wanted without it but it makes sense I wouldn't be feeling the plane yaw like this through the game.
Now take this adverse yaw to the runway, and demo how it is used supplement the rudder in maintaining directional conntrol. A simple X wind landing flow thru. X controled. Maintain the aileron PROPORTIONALLY OPPOSITE THE DESIRED RUDDER.
Samm, interesting printed concept. I'm interested to see how well your structure works for you. In my experience, the X cross brace structure like you have shown really doesn't do much for stiffness. If you're fighting top wing plate compressive buckling, either put a simple rib down the center of the wing or make the top thicker. In my experience, that's better use of material and weight in a shell type structure. Thanks for the vid. If I had instragram I'd comment there... but alas I dont.
+James Downing I didn't either but Carlee made me try it. Slowly growing on me. Thanks a lot for your advise on print structure, that makes a lot of sense. I haven't yet conducted structural testing but I think compressive buckling would be the first failure point.

You've enlightened me! RE
whoaaa whaaaa. So wonderful seeing a legend praising small channels like this
Good to see you here 🤗
Very cool. Nice to see the real life examples on real planes.

Rest easy Samm. Hope God is taking care of your family
I've never understood this until now. You're a great teacher.
That part where you swing the nose left and right and compared with and without rudder.... That was worth an instant like and subscribe.
I just discovered you and just learned you are in heaven. 😥

I watched about 10 videos explaining this, but your short video did it the best. Thanks!
Great explanation, simple and on point. It is just what you need to do a quick refresher on adverse yaw.
Excellent visuals here, thank you so much! 👏🏻 your teachings live on
I just reviewed this in my training. Your video provided all the visuals I needed to complete my understanding. Thanks!
Well done, Samm. You hit all the points and demo'ed beautifully. I will gratefully share with my students.
Great video as always, love the fast paced no-fuss delivery of information. You packed a lot of great stuff into 4 minutes and I wasn't bored.
Great video. *ACTUALLY* educative.
Excellent explanation and demonstration. I always wondered why rudders were needed. Thank you
Excellent demonstration, very easy to see it in this one. Good information that I hadn't heard before about ways engineers reduce the issue too.
Thanks Samm. Great explanation
I've always been a visual learner, as simply reading doesn't really do it for me. This video helped me tremendously, thanks!
Nice! This will help me fly better on a simualtor. Such a fundamental thing to understand!
Short and sweet. Thanks for teaching me something new!
Yes. Only 4 min. This is Question in CAT A Test. Very clear and easy to Understand.

finally I understand what the adverse Yaw is . Thanks for this video
Nice video. I believe the main purpose of the frize ailerons is to assist the pilot by reducing the effort needed on the yoke and that its effects on adverse yaw aren't that important.
Also nice coordination. Try doing that in a glider.
Is it worse in gliders because the wings are so long?
ABSOFREAKINGLUTLY
Also, look at most glider. The vertical stabilizer is much smaller than most powered aircraft.
+Samm Sheperd (SNRS) It's bad, even though I've only flown a glider, but from what I've seen, it's worse than the Piper.

Great explanation of adverse yaw and friese ailerons, thank you!
I'm a student pilot and this is such a great video! Good job!!
Nice video, Samm. I have always been a big believer in learning from both directions: practical and theoretical. One can always learn from the other.
Very clear and instructive video, thank you! This was very enlightening. I have noticed that I need to input some rudder to make my RC planes "turn nicely", and now I understand why :-)
Thank it so simple but not easy to understand at first. Make sense now!
fantastic explanation of adverse yaw. saving link to send to my students
awesome video i was also taught one hand on yoke one on throttle u don't really need both hands in the yoke
It's very helpful for understanding part of CPL POF. Thanks Samm!
thanks for your real flying example which made me understand the concept easily!

Thanks, by the way, printing a wing like that will make it very weak as the layer lamination will be the weakest point.
