Absolutelly impressive, Mr. RC! I am also an aviation teacher here in Brazil and you Sir will be my inspiration! Great class!

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!

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.

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.

Well said, your center of gravity comparison was very enlightening, thank you.

I hope my teacher in aviation when I grow up will be like you, you're really good and I got the lesson fast!

Your real good teacher thanks.

I love this theory and praxis explanations! It´s like going again to school or university :D

You did a fantastic job. Explained two reasons for lift, and drag component of flaps. Score of 100 out 100. Need teachers like you.

Grade 6 student here. I was extremely confused by this topic, thank goodness I came across your channel!

Just started working at an aerospace company. First day was deburring clutch plates for these flaps. So awesome.

I've been confused by how flaps work on planes,finally got an answer after 2 years of looking

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.

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 know this is not a new video, but I found it very helpful to confirm what I had already suspected. Thank you Bruce!

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.

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.

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.

Thanks Bruce! You are just an amazing asset to this hobby.

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

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.

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.

You did a great job explaining everything. Thank you soo much for simplifying aerodynamics

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.

Both are awesome. Thank goodness for variety!

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

Great video, has been much needed!

now i am learning more then i thought, which was nothing. great videos. love 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.

Easily best teacher I've ever seen.. been in school for a long time.

great video. finally understand them now

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!

Amazingly helpful. Thank you!

Another great video. Clear explanation. I won't need to look anywhere else, I think I've got it. Thanks for taking the time.

Briliant. I was struggling with the concept of centre of gravity and that added it all up.

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.

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

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.

Enjoyed this very much! Looking forward to the next one!

Great instruction and illustration Bruce.Thanks!

Fantastic video!!!! Well done! Greetings from a student pilot from Germany!

Super helpful, as an aspiring aviation simulator and someone going for my PPL license I greatly appreciated this.

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!

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

I thought I had a pretty good understanding of flaps before but this did widen my understanding, thank you! :)

Thanks for the video. I always learn something new watching them.

You teach like you invented aeroplane. I will like to make you my mentor. Great job done.

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 job Bruce! Thanks for all you do for the hobby

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.

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 info for a Noob in RC. Thanks for putting the time in to share your exeprance and knolage

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.

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

i now understand flaps ,thanks to you , keep up the very good work you do sir , all the very best .

Loud & very clear explanation. Thank you for sharing..

Great explanation Bruce, particularly since you spoke about the Newtonian part of it. The explanations I used to read as a kid really confused me as they made out that lift is only created by a wing with an airfoil shape, but I had model aircraft with no airfoil's or symmetrical airfoil's (control liners). When I studied engineering I learned that the Bernoulli effect is basically a statement of the law of conservation of energy.

Thanks Bruce, excellent tuition!

Enjoyed the lesson. Can't wait to see what is next. Thanks!

Very nice Bruce; Looking foreward to many more of these.

Thank you so much, I will slowly increase my flap. Very good advice!

Nice - exactly what I needed to hear.

Looking forward to the next lesson Bruce. Excellent video!

Great video as always, maybe an explanation of difference between 20 degree flap for more lift to help take off and 20 + degrees to give more drag for landings, As stated flaps have 2 main effects they create extra lift and also extra drag, up to 20 degrees (approx) the extra lift component is greater therefor assisting with take off, at more than 20 degrees the drag component becomes greater there for helping to slow the aircraft down and help with landings , This is why many aircraft have multiple or variable flap settings for different stages of the flight

Thanks Bruce, keep them coming.

Late to the party, but still an excellent video. I would like to add a warning to people who choose to go with "flaperons" on their model, (where ailerons and flaps share the same control surface). Especially when the model incorporates full length ailerons, (ie: aerobatic planes/flying wings etc.). You must be very careful of your speed and your directional corrections under these conditions. Any directional correction should be as minimal as possible. If you're flying your model with the flaperons deployed fully and the model is flying just above it's new lower stall speed, then you suddenly make a large correction with aileron input, the rising aileron will drastically reduce the lift thus taking away the extra lift the flap was giving and very likely stall that wing, causing a spin, if it has time to spin before it hits the ground. Just something to keep in mind.

Bruce, this is excellent work thank you very much. Keep these kind of videos coming!

Great video. I learned that I had the wrong idea about flap deployment, but now I got the idea. Thanks!

Well explained, Bruce. Looking forward for more similar videos

Excellent introduction to lift and flaps Bruce. Well done. yes, I know that there are assumptions and a few people are pointing those bits out. BUT you are doing a basic introduction. And that is the point. Clear, concise and fun. Congratulations and all the best, Lincolnshire Rose.

Great video. You make it all seem very easy to understand. Thank you

Excellent presentation. Thank you

I'm a beginner and this video helped me a lot. It's perfect for people like me.

You're the best my friend! We are learning so much from you!

Bravo,Well done! I've noticed a greater torque roll effect when accelerating with flaps down.

simple yet concise. much better understanding now thanks

Another great video! Making a complex topic easy to understand.

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.

I see forward to the next one, have a good one Bruce

great vid Bruce.Looking fwd to some more.

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.

Man! Awesome video on flaps. I have watched you since I've started RC

Fantastic new segment. Great explanation.

great video! I'll be watching all in the series, get busy! :)

Perfect teaching for me. Is simple to understand! Thanks young man!

Outstanding as usual! I'm grateful for your efforts - thanks so much. BTW, is there a way one can set up an AoA system for FPV using air speed sensors or something? Cheers!

Thank you for the explanation!

Excellent examples, especially on the above wing as compared to the lower wing craft types., Thank you.

Really clear explanation of flaps - I have a much better understanding now, thank you!!

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.

Thank you!! It is going to help me use my flaps on my Challenger, your explanation is very easy to understand.

I'm voting for "white board Wednesday". Love your videos by the way.

This video is more than adequate to help people understand flap use.

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.

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 Bruce. I'm 56 and new to this that was great.

Sir, pls more of such theories videos !!! This was really helpful !! we want more of "THEORY TUESDAYS"

14:57 excellent just what I was looking for to understand flaps thank you

Excellent explanation! Very clear and informative! Great teacher!
