- 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.
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.
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.
Dave Flysitall he needs better teachers

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 great job explaining everything. Thank you soo much for simplifying aerodynamics
I love this theory and praxis explanations! It´s like going again to school or university :D
Grade 6 student here. I was extremely confused by this topic, thank goodness I came across your channel!
great video. finally understand them now
Amazingly helpful. Thank you!
Thanks Bruce! You are just an amazing asset to this hobby.
You did a fantastic job. Explained two reasons for lift, and drag component of flaps. Score of 100 out 100. Need teachers like you.
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.
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.

I've been confused by how flaps work on planes,finally got an answer after 2 years of looking
I know this is not a new video, but I found it very helpful to confirm what I had already suspected. Thank you Bruce!
Another great video. Clear explanation. I won't need to look anywhere else, I think I've got it. Thanks for taking the time.
Just started working at an aerospace company. First day was deburring clutch plates for these flaps. So awesome.
Thank you so much, I will slowly increase my flap. Very good advice!
Excellent presentation. Thank you
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!
Thank you for this vídeo and explanation. Very well demonstrated! Nice job!
Loud & very clear explanation. Thank you for sharing..
Enjoyed this very much! Looking forward to the next one!
Great video, has been much needed!
simple yet concise. much better understanding now thanks
Great video. You make it all seem very easy to understand. Thank you
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.
Easily best teacher I've ever seen.. been in school for a long time.
Another great video! Making a complex topic easy to understand.
Both are awesome. Thank goodness for variety!
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.
You're the best my friend! We are learning so much from you!
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.
Great job Bruce! Thanks for all you do for the hobby
Thanks Bruce, excellent tuition!
Perfect teaching for me. Is simple to understand! Thanks young man!
Great instruction and illustration Bruce.Thanks!
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

I thought I had a pretty good understanding of flaps before but this did widen my understanding, thank you! :)
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.
Bruce, this is excellent work thank you very much. Keep these kind of videos coming!
awesome explanation! Thank you teacher!
It's defiantly subscribe! Thanks for you awesome explanation!
Excellent explanation! Very clear and informative! Great teacher!
now i am learning more then i thought, which was nothing. great videos. love them
Enjoyed the lesson. Can't wait to see what is next. Thanks!
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.
Man!
Awesome video on flaps.
I have watched you since I've started RC
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.
You teach like you invented aeroplane. I will like to make you my mentor. Great job done.
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.
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.
Excellent job!
Nice explanation. Keep up the great work!
Don
Thanks man.
The video was soooooo great.
I leaned alot.
i now understand flaps ,thanks to you , keep up the very good work you do sir , all the very best .
Really clear explanation of flaps - I have a much better understanding now, thank you!!
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.
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.
Super helpful, as an aspiring aviation simulator and someone going for my PPL license I greatly appreciated this.
Awesome video. Very well explained. Cleared up all of my doubts. Thank you, sir
Fantastic video!!!! Well done! Greetings from a student pilot from Germany!
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!
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
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
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
Briliant. I was struggling with the concept of centre of gravity and that added it all up.
Well done, Good teacher. Thank you.
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...
Fantastic new segment. Great explanation.
Thanks for this, i really enjoyed it.
Good on you Sir. Very clear, concise and informative explanations. Thanks
Killer as always!!! Your a born teacher.
This is the best video for the given topic. Thank you for explaining the theory. :D
what a great lesson, it really cleared up my understanding about the flaps for different plane model
Sir! this is an amazing explanation! Thank you for your work!
You sir are a fine instructor! I like both of your channels.
Thank you for the explanation!
Great video. I learned that I had the wrong idea about flap deployment, but now I got the idea. Thanks!
I'm a beginner and this video helped me a lot. It's perfect for people like me.
Nice - exactly what I needed to hear.
great video! I'll be watching all in the series, get busy! :)
Great video very informative.Thanks.
Thank you!! It is going to help me use my flaps on my Challenger, your explanation is very easy to understand.
Thank you so much ! The explanation was awesome :)
It ties in nicely with my aerodynamics course, thank you
Looking forward to the next lesson Bruce. Excellent video!
Very nice Bruce; Looking foreward to many more of these.
Wonderful Teacher!!! Very nicely explained!!! Thanks a lot!!!
Thanks Gramps. You are great.
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.
Excellent explanation does the same in my piper cub....Cheers to the white board....
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!
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.
Great Video man! Very well explained. Thank you
Thanks a lot!!!! GREAT VIDEO. I love you man, RC is not just the hobby of the younger ones :-) I love it. Great explanations…
