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

@lambertodgr8 Год назад

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 .

@LLH7202 Год назад

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!

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!

@manaoharsam4211 2 года назад

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

@kenbarnett8189 9 лет назад

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

@Ritefita 2 года назад

yes! Then why didn't he said about planes with a wings AT the center of mass? Do they exist?

@cliftondalezirkleii8670 10 лет назад

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!

@konturger 10 лет назад

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.

@nocare8529 10 лет назад

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

@steelydanfan100 6 лет назад

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.

@nielskistrup8231 3 года назад

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.

@luke_atthat 4 года назад

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.

@cayrick 7 лет назад

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.

@shoestring405 10 лет назад

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

@PetrincicBrosRC 2 года назад

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

@spot2be 10 лет назад

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.

@MrNuggin 6 лет назад

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!
