Thank you for your time great info. I was hoping this video was showing you building washout in the wing.

Nice video, the only thing I’ve intensional have put washout in is on sailplanes. That gets twisted in when cover the wing. But I’ll give it a try on my next build of an powered fixed wing aircraft and try building it in!

thank you so much for doing this video because it did clear up a lot of things for me and you help me understand the difference between Wing Incidence and Wing Washout , because I definitely were getting those two confused I thought they were the same , but I really enjoy learning new things even though I'm 66 years old but you cleared up more things for me than what I could find on the Internet , as I said before both my builds that I am going to be doing on the B-29 and eventually the B-17 both of these aircraft are not going to fly I'm just going to use these were static display at airshows so people can enjoy seeing models built on the scale and hopefully it gets them interested into this hobby on building their own aircraft instead of buying prebuilt , but also both of these aircraft I am going to build them as if they were going to fly in the reason that is I want to challenge my skills and my knowledge on building something this size and complex , I hope that makes sense ? But my hat is deftly off to you for building that beautiful B-36 pacemaker bomber which is absolutely a work of art and not telling you what to do or not to do , after all that hard work that you put into that I think you should also just keep that to show people what can be done and display that at your local airshows and events I know personally I would love to see that B-36 bomber because that would be amazing , but once again I greatly appreciate everything that you do by creating these videos to help people like myself to understand better and to learn new things

Nice video! 3° is what I have on tu -95. with its 35°/30° sweep wing and 3 wing fences

Thanks for this video! the RC world needs to share more about this type of thing. I've tried to do my fair share on my channel, talking about adverse yaw, and different configurations. The rudder mix trick is a very useful one. especially on high aspect ratio planes. I fly some very high aspect ratios, and often use 100 percent mix. and sometimes limit aileron throw to push it further. it really works. Would also be nice to talk sometime about provers yaw, as it relates to washout. and span wise lift distribution, elliptical vs bell shaped. Prandtal had some interesting findings on that. a bit of washout can actually increase efficiency. because the airflow already has some span wise flow and there is already a vortex near the tip, so allowing some wing twist can reduce drag a little. And lets' not forget to mention progressive airfoils in wings, (they can do a similar thing as washout, and are sometime used together, such as on the dc-3 ) as well as a changing Reynolds number due to wing taper. Planform, and how it affects stall characteristics. turbulent vs laminar flow, intentional boundary layer separation, etc. and how they affect stall characteristics, as well as efficiency. also blown wings, and how power can affect aggravated power on stalls on multi engine aircraft, especially twins. lots to talk about on this topic. Great video!!!

is there a degree maximum of washout to build in. I've drawn 4° into the tip of my project model. F111 it's got a lot of tapper to the shape,. 16° leading edge with 1° trailing edge. was thinking the high wash out would help remove tip stall that I'm expecting this shape wing to have with the tip having such a short cord compared to the root. root section NACA 2412. tip section NACA 2416

@@russcole5685 I am not sure at what point would be to much. I have seen 2.5 degrees a few times, and 3 degrees as the max. But, I would guess more would work, but you root incendnce may need to be higher, for the wing to produce the right amount of lift in relationship to the fuse angle. :) Rock ON!

16:32 You got over 105 emails about a video you uploaded a few weeks ago that has 700 views and 5 people making comments, and your email address is not even in the description?? That doesn't sound right at all. I've had maybe 50 emails over 12 years across the entirety of my channel from 664 videos and 15 million views, and people always want something. I never had a single email just to say a video was good. Maybe I need more, or better, friends :)

I should have clarified. The same video is uploaded to my Facebook. To date I have PMs and e-mails. 75 e-mails and 35 PMs. Not sure what to say, my e-mail is in many of my videos at the end. I get about 25-40 PMs and e-mails a week on average. Rock On!! I also do one on one classes with zoom about design. I get a lot of e-mails from those also.

So wash out was originally used with young inexperienced less than optimally skilled Pilots? According to the information you have. Wouldn't you have to fly the airplane first to determine if wash out was required rather than just eyeballing it. Isn't it true that the plane even with washout will still stall? If flown beyond the max angle of attack? Experimenting with a plane after flying it given your weight and CG is correct, couldn't the same things be said for Wing incidences engine thrust modifications? I've heard guys when building from plans say that the plans required a certain amount of washout I always wondered why? I'm not convinced that omitting washout, is really going to make the plane fly poorly or compensate for bad piloting skills. Had your friend spent some of those 3 years in developing good flying skills rather than putting thousands of rivets on an airplane he might just have saved it. This is why I take exception with the guys who say they like building as much as flying. First and foremost this is a flying Hobby. Building is all well and good, knock yourself out do whatever you want, but I am trying to change everyones definition of the hobby, heaven for bid. Recognize that most of the guys that don't commit to developing required skills is because they're afraid to, or they have no one to guide them and that's why many leave the hobby, they plateau, in many cases. Your friends' crash made him confront the fact that he didn't have the skills he need as a flying/builder, and he wouldn't face this and overcome it. Interesting video, but I believe it gives people an insignificant detail to focus on rather than spending time flying or on a simulator, developing the skills needed to fly their lead sled.

Something to think about. I have taught 101 people to fly RC in the last 30 years. When a person is first learning to fly they need a plane that is forgiving. A wing with zero washout can stall abruptly. But an aircraft with washout will stall at the inboard. This gives you a bit of aileron control. On a trainer, this is great. Washout has been built into many full-scale planes for years. There's a reason why. My quest in life is to make successful RC pilots. I have a good record of that. It's interesting as I have never had a negative post about washout on an RC plane until you. I will take that for what it is worth. I help people make bad planes fly better and good planes fly great. I never said anywhere that should supersede learning to fly or having more stick time over building. Thanks for the post and have a fantastic day! Rock ON!
