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
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!
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.
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.
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 :-)
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!
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
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 ! th-cam.com/video/yKpq9FZMPqQ/w-d-xo.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).
Samm will no longer be able to answer bro ... When you turn your plane on yaw, you induce roll. Imagine you yaw on left, right wing will travel faster then left wing, inducing more lift and causing the right wing to go up, if you apply yaw to go left, you will have roll too. Hope you understand, excuse my poor english
nice video, awesome that you fly full scale, also the printed wing looks interesting, no supports for the diagonal spars? assuming you printed cross section up.
When I see prints of "floating" or "unsupported" members like say the petals on a rose, the petals would have vertical supports printed from the bottom up to where the petals are cantilevered. I was curious regarding the internal cross "spars" not sure what to call them. The diagonals with the circles cut out.
+Jacob David C. Cunningham I think the printer would be able to print the ribs if they were printed horizontal like normal with out any supports. However the printer can handle 45° no problem and it works really well structurally.
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.
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.
Excellent video Samm. Learned a lot
Real Engineering I bet he learns a lot from you too
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.

That part where you swing the nose left and right and compared with and without rudder.... That was worth an instant like and subscribe.

Rest easy Samm. Hope God is taking care of your family
I just discovered you and just learned you are in heaven. 😥
Rest in peace Samm. Thank you for the amazing video
I watched about 10 videos explaining this, but your short video did it the best. 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.

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.

I'm a student pilot and this is such a great video! Good job!!
Okay this is one of the best explanations ever! Thank You
Nice! This will help me fly better on a simualtor. Such a fundamental thing to understand!
Great explanation of adverse yaw and friese ailerons, thank you!
RIP in Samm.
Short and sweet. Thanks for teaching me something new!
Now that is some great info and test! Thanks Sam.
Best explination I heared yet. I loved the nose swinging around demonstration: Never seen that before.
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.
ayy, we both own sidekicks
keep making the content Sam, good stuff as always.
So, this guy taught me more in 4 min, than my Flight mechanics teacher did in a one-hour lecture...
You definitely deserve more subscribers
Thanks Samm, awesome demo!
fantastic explanation of adverse yaw. saving link to send to my students
Very clear and practical explanation of adverse yaw, thank you sir!
awesome video i was also taught one hand on yoke one on throttle u don't really need both hands in the yoke
Great flight example. Straight to the point video.
Yes. Only 4 min. This is Question in CAT A Test. Very clear and easy to Understand.
I've been flying so long I don't even think about it. Thanks for that.
The best video about adverse yaw!
Finally understand this, thanks so much! Really liked the animations and the real life flying footage, it helped a lot
Thank it so simple but not easy to understand at first. Make sense now!
An excellent lesson for student pilots

Now that is some great info and test thanks sam
