How aircraft flaps work
Ғылым және технология
A whiteboard explanation of the theory behind lift and flaps in what is the first of a series that attempts to explain the science behind the technology we use in our RC planes.
I've tentatively called this series "Theory Thursday" but it might also be Technical Tuesday or Whiteboard Wednesday -- you tell me :-)
And if you've got ideas for new theory videos, mention them in the comments below.
Also, if you have any questions about this video, ask-away and I'll do my best to answer them.

Absolutelly impressive, Mr. RC! I am also an aviation teacher here in Brazil and you Sir will be my inspiration! Great class!
How did I miss the Newtonian component all these years? It was right in front of me but I never had someone explain it so well.

SYMMETRIC AIRFOILS & FLAT PLATE AIRFOILS work on ONLY NEWTONIAN LIFT PRINCIPLE ..NO FANCY BERNOULLI LIFT

Having only taken up flying on retirement at age 75 I have a lot to learn .your videos put things simply so that my senile brain can understand .

If you think about it, a propeller is nothing more than a rotating wing. It produces lift to create thrust. Bernoulli says that the low pressure area ahead of the prop sucks the plane forward to produce thrust. Newton says the the air is accelerated backward to produce thrust in the same way a jet engine does. Which is true? Both.
I don't hobbie in RC aircraft but this is obviously applicable to full sized aircraft. Very clear and concise video with a great host. Thanks very much!
Your real good teacher thanks.

As a licensed flight instructor (and rc modler) I must say, great video. You clearly have a good understanding of flight characteristics and can demonstrate/explain it very well. More of these kinds of videos would kick ass. Ok bye.
I hope my teacher in aviation when I grow up will be like you, you're really good and I got the lesson fast!
Well said, your center of gravity comparison was very enlightening, thank you.

yes! Then why didn't he said about planes with a wings AT the center of mass? Do they exist?
You did a fantastic job. Explained two reasons for lift, and drag component of flaps. Score of 100 out 100. Need teachers like you.
Just started working at an aerospace company. First day was deburring clutch plates for these flaps. So awesome.
Thanks Bruce! You are just an amazing asset to this hobby.
Grade 6 student here. I was extremely confused by this topic, thank goodness I came across your channel!
Bruce you gave a great presentation today on flaps. I had read an article last weekend about flaps and your pictorial explanation helped my understanding even more. Great job!
A BIG BIG BIG THUMB UP !!! - I really enjoy your videos, as a X-Plane Sim Pilot, and real life Skydiver with over 200Jumps, this is total perfectly brought to the point. Will be watching your videos in future! Keep things going on, like this! Cheers from Germany.
Fantastic Explanation! I am a multiengine and instrument rated private pilot and I have never heard such an in depth explanation about flaps before even though I have gone through years of study. Great job! Keep the videos coming. Jake from the USA.
I've been confused by how flaps work on planes,finally got an answer after 2 years of looking
Easily best teacher I've ever seen.. been in school for a long time.
I love this theory and praxis explanations! It´s like going again to school or university :D
You did a great job explaining everything. Thank you soo much for simplifying aerodynamics
great video. finally understand them now
Great instruction and illustration Bruce.Thanks!
Both are awesome. Thank goodness for variety!
Amazingly helpful. Thank you!
Great video, has been much needed!
Another great video. Clear explanation. I won't need to look anywhere else, I think I've got it. Thanks for taking the time.
Super helpful, as an aspiring aviation simulator and someone going for my PPL license I greatly appreciated this.
now i am learning more then i thought, which was nothing. great videos. love them
I knew very little about how flaps and how other items on an airplane worked but this presentation was very very good and understandable to me.
I appreciate that you at least mention that the Bernulli effect as a explanation of why air-planes fly is at least disputed. The Newtonian explanation makes so much more sense and I'm convinced it is responsible for the majority of the lift created.
Enjoyed this very much! Looking forward to the next one!
Loud & very clear explanation. Thank you for sharing..
Thank you so much, I will slowly increase my flap. Very good advice!
I know this is not a new video, but I found it very helpful to confirm what I had already suspected. Thank you Bruce!
amazing... its been a while but you had been teaching and explaining RC plane to us. Good job and thank you for the hard effort.
Thanks Bruce, excellent tuition!
more please Bruce as a newbie found it interesting and informative and for a man of more advanced years and into this hobby for the first time
Thanks for the video. I always learn something new watching them.
Thank you. I learned new things today. I've always know how wing works with Bernoulli principle but for the Newton principles, it's the first time for. Very precise and clear explanation. Thank you again for this great video.
As a fixed wing private pilot I knew there were 2 kinds of lift but only the name of the Bernouli lift. I always called the other one "deflection lift" when the flaps were down. The best way to demonstrate both is to take a narrow strip of paper and hold it in front of your mouth. Blowing across the top of the paper gives you Bernouli Lift and blowing below the paper gives you Newtonian Lift. A clean wing is all Bernouli Lift and as you add flap you get less of that and more Newtonian Lift with more drag and therefore slower speed / lower stall speed for landing.
Great video. You make it all seem very easy to understand. Thank you
This video is more than adequate to help people understand flap use.
Excellent explanation on what flaps are good for. Don't own an R/C aircraft, but practicing w. the E-flite EC-1500 (which has a 3-position flap setting). Applying what you taught me, is leading to much smoother landings.
I thought I had a pretty good understanding of flaps before but this did widen my understanding, thank you! :)
Excellent presentation. Thank you
Thanks so much for your video. I was having a discussion with my three sons about the effect of flaps on aircraft and your video explains it very nicely in plain English that even my 9 year old should be able to follow. Cheers Kev
simple yet concise. much better understanding now thanks
Enjoyed the lesson. Can't wait to see what is next. Thanks!
You teach like you invented aeroplane. I will like to make you my mentor. Great job done.
You're the best my friend! We are learning so much from you!
Great job Bruce! Thanks for all you do for the hobby
Thank you for the nice explanation on flaps. Now I understand why they recommand to put a bit of elevator down to a high wing.
Thank you a lot, please keep making videos of HOW IT WORKS. Cant wait till you will start explaining the electronics, please do not miss anything.
Great video, I am just getting back into model airplanes and my Dynam Hawksky 4 CH motor glider needs flaperons, it glides so well, I need an acre and a half just to land ! Your whiteboard and ability to hold 4 colored markers while talking and drawing is remarkable. I know I needed flaps, I can now explain why to someone else, that is the lesson learned today.
Excellent explanation! Very clear and informative! Great teacher!
Totally spot on ... For advanced learners l'd like to add ... Flaps change wing camber & above all wing chord. Meaning increasing angle of attack (AOA) by some 5 degrees despite plane staying in same orientation. Plus control surfaces lose authority at slow speeds &n controls feel mushy

since the presentation begin with a FLAWED visual aid, 'spot on' is not what i would Call it.
Bruce, this is excellent work thank you very much. Keep these kind of videos coming!
I'm trying to build a plane in ksp, and this really helped. I had no clue what flaps were for, or even what direction to angle them before watching this video.
Nice - exactly what I needed to hear.
Simply excellent Bruce! I enjoyed this very much. I just don't see how anyone could give this a thumbs down. Free and accurate information presented well. Probably five of the "Old Sore Heads" just pouting.
I'm a beginner and this video helped me a lot. It's perfect for people like me.
what a great lesson, it really cleared up my understanding about the flaps for different plane model
Great info for a Noob in RC. Thanks for putting the time in to share your exeprance and knolage
Another great video! Making a complex topic easy to understand.
Looking forward to the next lesson Bruce. Excellent video!
Perfect teaching for me. Is simple to understand! Thanks young man!
Wings are amazing machines. When ever I fly I am always fascinated by the complex flap mechanism at takeoff and landing
Great video. I learned that I had the wrong idea about flap deployment, but now I got the idea. Thanks!
great video! I'll be watching all in the series, get busy! :)
Well done Bruce. I enjoyed this presentation. I am looking forward to technical Tuesday or theory Thursday I think the new studio will be a great asset to what you're doing. I have been following your videos for quite some time. I find them both educational and entertaining. Donation to help with the studio (and my future education) on its way. Keep up the good work Bruce
Sir, perfect explanation. I am starting my training in half a year from now and I am glad i found Your content. Hope you are doing well!
i now understand flaps ,thanks to you , keep up the very good work you do sir , all the very best .
Thank you!! It is going to help me use my flaps on my Challenger, your explanation is very easy to understand.
Really clear explanation of flaps - I have a much better understanding now, thank you!!
We are not asking for a physics dissertation here but an understanding that works. Your explanation gets the point across very well. Let the egg heads prepare a complex video with angle of attack and other variables that will put viewers to sleep. This certainly helped me to understand the concepts he was trying to convey and I thank him for it.

Man! Awesome video on flaps. I have watched you since I've started RC
Well explained, Bruce. Looking forward for more similar videos
Wish you'd been my teacher at school. Complicated theory explain easy terms. THANK YOU
Wonderful Teacher!!! Very nicely explained!!! Thanks a lot!!!
Very nice Bruce; Looking foreward to many more of these.
It ties in nicely with my aerodynamics course, thank you
Fantastic new segment. Great explanation.
Thank you for this vídeo and explanation. Very well demonstrated! Nice job!
lastly im glad you are making these videos. I am also glad they are simple as most people wont care about the higher complexity stuff. Just try and do a little refresher research to make sure the simplification is not misleading
Thank teacher I love watching your flight lessons time and again bravo !!!
Killer as always!!! Your a born teacher.
Thanks man. The video was soooooo great. I leaned alot.
Thanks Bruce. I'm 56 and new to this that was great.
awesome explanation! Thank you teacher!
I see forward to the next one, have a good one Bruce
Awesome video. Very well explained. Cleared up all of my doubts. Thank you, sir
Thanks mate, I've been scared to fly my brand new first plane incase I F up and suck at the landing and the info you've shared in here is brilliant for newbie me.
Thanks Bruce, keep them coming.
Brilliant informative video on lift theory and flaps, particularly pitch difference between low wing and high wing configurations, should be compulsory viewing for all new rc pilots.
Hi! It would be nice to see here Lilienthal's Polar Diagram, but anyway comprehensive presentation. Probably worth mentioning (or with more emphasis) - flaps are mainly drag generating devices (lift is not the main part here :). One equation to remember is quite easy in that case: Cdi (induced drag coefficient) = Cl^2 (lift coefficient squared) / Pi * AR (wing aspect ratio) Cheers!
Excellent examples, especially on the above wing as compared to the lower wing craft types., Thank you.
Great Video man! Very well explained. Thank you
I learned a lot from Mr Bernoulli when I started messing with carburettors 40 years ago, and more when I began making and flying kites from about 25 years ago. So I'm only too happy to recognize him as one of the family along with my best friend Albert E. They both solve the airplane on the conveyor belt question.
Well done, Good teacher. Thank you.
Thank you for the explanation!
Excellent explanation does the same in my piper cub....Cheers to the white board....
Amazing video for beginners !!
