- 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. - Věda a technologie
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.
Its ok, you're not the only one.
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.
Absolutelly impressive, Mr. RC! I am also an aviation teacher here in Brazil and you Sir will be my inspiration! Great class!
I love this theory and praxis explanations! It´s like going again to school or university :D
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!
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!
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.
You did a fantastic job. Explained two reasons for lift, and drag component of flaps. Score of 100 out 100. Need teachers like you.
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?
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!
You did a great job explaining everything. Thank you soo much for simplifying aerodynamics
I know this is not a new video, but I found it very helpful to confirm what I had already suspected. Thank you Bruce!
Your real good teacher thanks.
Dave Flysitall he needs better teachers

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.
Thanks Bruce! You are just an amazing asset to this hobby.
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.
Another great video. Clear explanation. I won't need to look anywhere else, I think I've got it. Thanks for taking the time.
Easily best teacher I've ever seen.. been in school for a long time.
Loud & very clear explanation. Thank you for sharing..
You teach like you invented aeroplane. I will like to make you my mentor. Great job done.
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.
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!
Disregard my last comment. It wasn't your video but my computer. I tried again and it worked really good and was able to watch your video. Thanks for taking your time to share your knowledge with your subscribers.
I'm a beginner and this video helped me a lot. It's perfect for people like me.
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.
Great video. You make it all seem very easy to understand. Thank you
Just started working at an aerospace company. First day was deburring clutch plates for these flaps. So awesome.
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.
Great instruction and illustration Bruce.Thanks!
simple yet concise. much better understanding now thanks
Another great video! Making a complex topic easy to understand.
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
Excellent explanation! I was also a Grade 1 instructor and now I'm a B767 captain. A point of interest, the advanced flaps such as Fowlers, and leading edge slats, also increase the surface area of the wing and so increase the lift
Am excited to hear that you are a captain
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
Thanks for the video. I always learn something new watching them.
Fantastic video!!!! Well done! Greetings from a student pilot from Germany!
Great job Bruce! Thanks for all you do for the hobby
Amazingly helpful. Thank you!
Excellent explanation! Very clear and informative! Great teacher!
great video. finally understand them now
Perfect teaching for me. Is simple to understand! Thanks young man!
Mate...loved your presentation and it was so very helpful. Have always wondered the importance of flaps and you have explained it simply and easy to understand. Hat off to you and will be watching many more of your vids.. GREAT WORK...
Super helpful, as an aspiring aviation simulator and someone going for my PPL license I greatly appreciated this.
This video is more than adequate to help people understand flap use.
Both are awesome. Thank goodness for variety!
i now understand flaps ,thanks to you , keep up the very good work you do sir , all the very best .
Enjoyed the lesson. Can't wait to see what is next. Thanks!
Sir! this is an amazing explanation! Thank you for your work!
now i am learning more then i thought, which was nothing. great videos. love them
I've been confused by how flaps work on planes,finally got an answer after 2 years of looking
what a great lesson, it really cleared up my understanding about the flaps for different plane model
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.
Really clear explanation of flaps - I have a much better understanding now, thank you!!
Enjoyed this very much! Looking forward to the next one!
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.
I thought I had a pretty good understanding of flaps before but this did widen my understanding, thank you! :)
Thanks Bruce, excellent tuition!
Fantastic new segment. Great explanation.
You sir are a fine instructor! I like both of your channels.
Great video. I learned that I had the wrong idea about flap deployment, but now I got the idea. Thanks!
Great info for a Noob in RC. Thanks for putting the time in to share your exeprance and knolage
You're the best my friend! We are learning so much from you!
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
Man!
Awesome video on flaps.
I have watched you since I've started RC
Great video Bruce. I love it. I still learn every day about this amazing hobby. Was just exploring today how slats work becouse I was doing maiden with Storch that have slats on. Pretty interesting how they work. Thanks for posting and big salute from Slovenia, Pilot Robert
Very nice Bruce; Looking foreward to many more of these.
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.
Good on you Sir. Very clear, concise and informative explanations. Thanks
Looking forward to the next lesson Bruce. Excellent video!
Excellent examples, especially on the above wing as compared to the lower wing craft types., Thank you.
Awesome video. Very well explained. Cleared up all of my doubts. Thank you, sir
Excellent presentation. Thank you
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.
Thank you for this vídeo and explanation. Very well demonstrated! Nice job!
Great video, has been much needed!
great job, bruce. obviously, there is more to it, but that was the best overall explanation i've heard in a long time. would love more on coanda, though. thanks for all you do!
Hi Bruce,
Wasn't sure I'd learn anything, but I like your vids and decided to watch the new 'teaching' segment. I never thought about position of the wing and center of gravity and resulting pitch when flaps are deployed. So I did learn something. Thank you.
Aaron,
The change in airflow over the horizontal stabilizer (HS) with flaps deployment is the largest determinant of how the airplane will react. An airplane with a HS that is lower than the wing will generally have a nose up tendency, where an airplane with a HS that is higher than the wing will generally have a nose down pitching tendency.
Great job of explaining this in simple terms...thank you sir
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.
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.
Excellent explanation does the same in my piper cub....Cheers to the white board....
Thank you!! It is going to help me use my flaps on my Challenger, your explanation is very easy to understand.
14:57 excellent just what I was looking for to understand flaps thank you
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.
Bruce, this is excellent work thank you very much. Keep these kind of videos coming!
Bruce, Very well done. I really appreciate your knowledge of the science of flying rc planes. I am very interested in what makes our planes fly and why. You have done a really good job in explaining and breaking it down for us simple minded people to understand. I would like to see a video on the differences of pusher and puller motor ? props and there benefits and down sides. Thanks again and keep up the good work!!!
Scott
Thank you so much, I will slowly increase my flap. Very good advice!
Wow! I just came across your brilliant video. Very informative. Thank you Sir!! I love your explanation. I'll check in a moment but if you or someone else hasn't answered before, could you please make a video on what the difference is between an aileron and a flap. Many thanks!
Well explained, Bruce. Looking forward for more similar videos
Excellent job!
Nice explanation. Keep up the great work!
Don
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!
great vid Bruce.Looking fwd to some more.
This is the best video for the given topic. Thank you for explaining the theory. :D
Thank teacher I love watching your flight lessons time and again bravo !!!
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
Very nice and quite educative. Thanks for sharing.
Thanks. Your video was a good explanation of both lift & drag.
