How to Build an Easy and Inexpensive Model Airplane that Flies

[@larzhillbot1443]

Great lessons and nice simple designs been building rc foam planes for years but free flight gliders are a Great Learning tool and teaches trimming High five to ya

[@iandaly8786]

Excellent video. Great that you are using less expensive materials. Hope we all end up making radio control airplane that doesn't cost the earth and is easy & cheap to repair!!!

[@janvh90]

This video is exactly wat I was searching for! Thanks for this awesome content

[@malcolmking752]

Love this video! Keep making content! I love the straight to the point style, and love the simple free flight designs. You’ve inspired me to build something like this.

[@eleazarguzmanrn6945]

You explained the instructions really well, thank you.

[@abdulmueed4013]

Loved the details that you have provided here and pleased to see quite a practical approach. Very Well Done....

[@falcopilot7519]

Your Talking style is very nice 😊, and great work

Design question: At 4:25 what made you decide that 30" x 5" Area and the dimension for the other components was the most optimal? What is the design philosophy/mathematical reasoning behind this decision? Or was it simply something you have to brute force with testing to get to this conclusion?

[@DesignYourOwnAirplanes-xd6lz]

I chose a wing area of 150 square inches because I wanted the plane to have a wing cube loading between 3 and 4 (I talk about wing cube loading in the next video). I also chose an aspect ratio of 6 so that the wing would be long and skinny enough to provide decent efficiency, but also wouldn’t be too flimsy. I’ll talk more about aspect ratio, efficiency, and aircraft structures in some later videos.

Things like this should be part of our schools math curriculum

[@boywithadolphin]

This is a great video! Like how it is easy to build. Be interesting to make it into a powered aircraft.

[@notssimoo]

nice glider!! i have a question. what thickness is the foam sheet?

[@DesignYourOwnAirplanes-xd6lz]

0.2 inches, 5 mm

[@wlbraun2024]

Very interresting, very stright forward.

[@sharadsingh25]

Amazing Work !! Loved It ❤

This was a good level for beginners, though a couple paragraphs equivalent explaining some of the terms (wing chord, leading and trailing edges, for instance) wouldn't have come amiss. You might also have mentioned that adjustments by moving the nose weight, adding or subtracting weight, or adjusting the tail incidence should always be *small* -- big moves like the ones you showed will result in overcorrection and "chasing the CG" -- in fact, it might be sensible to point out that the airplane should balance at or close to the high point of the wing with your default of 3-4 pieces of scrap wood (i.e. 3/16 to 1/4 inch of tail incidence).

Congratulations on your work as a teacher in this video tutorial. 😁👍😉 My father and I love easy-to-build free-flying models. 😛 I suscribe at your channel . Greetings from Denmark and from Argentina. 🙋‍♂️ JH 🇩🇰 JOSS 🇦🇷

Thank you, found all the materials at Walmart!

[@robohippy]

If your plane wants to fly to the right or the left, this is seldom a weight issue. It can be the tail being out of line. Most of the time you need the wings to be 'fine' tuned so they match each other. If one wing has a bit more wing warp than the other, it will turn to the more warped side. Always vide the wings both from front and back to make sure they are the same.

[@redskyz483]

But it could be a weight issue couldn't it .

[@robohippy]

@@redskyz483 It 'could' be a weight issue. I balance mine before I put them on the plane. With the ones I have built, if they are balanced, then it is a fine tuning issue.

[@redskyz483]

@@robohippy Therefore he is correct in his video.

[@DesignYourOwnAirplanes-xd6lz]

I decided to go with the weight method because I found it easier and more reliable than fine tuning the wings.

[@redskyz483]

@@DesignYourOwnAirplanes-xd6lz your video was very good .

[@gebackenebananee5743]

I love this video you just earned sub number 24! 👍

[@weseehowcommiegoogleis3770]

The FAA will target these soon enough.

[@billkraemer4710]

Yup. They don’t like not being in control.

[@VimalKumar-z7d]

great job

[@RobFeldkamp]

But that's enough talk, let go build! * cut to: * Before we begin 😂

[@mesvideostube]

I love it, thanks

[@Mutawakil-n5e]

Keep it up I really appreciate it Just one thing Next time name or number the episodes because some people use to downlaod these videos

[@joeldobbs7396]

Thanks for the modular design idea! It didn't occur to me to use wood for the body either. I get lots of scrap foam insulation off cuts from work so I have been making everything with that. Soooooooo much sanding, soooo much dust. I like using it anyway because if you dissolve the insulation dust in naphtha you get some nasty home made napalm. Hmmm, at 53 maybe I should not do things like that, maybe I should go and fish at the local pond and complain about politics with the other adults. Maybe I should stick two forks in the toaster and sit on it, more fun than fishing by far.

[@ictconsultant7509]

Keep up your good work Sir. Can you assist mentoring my 8 year old boy who is very gifted in Aircraft design?

[@jeffkeith637]

Subbed. Nice easy design. Cheers.

the glider on your left , i had as a kid.

[@angularfpv6572]

Love it. Keep going!

[@band0804]

Nice man!

[@redskyz483]

Very good video

[@boywithadolphin]

How do I contact you? You are the best designer I have found on KZbin. Well done!

[@DesignYourOwnAirplanes-xd6lz]

Thank you! The comment section would probably work best for now. I might set up an email account for the channel soon.

[@kaffeetasse2461]

boring without rc. i used the good software 'winschwer' to calculate the center of gravity for any form of plane you like. how do you calculate the centerofgravity? and the angle of attack? i did it like you, i bought all my material in the hardware store. wood sticks for stiffing the wing, and foam plates for the whole plane and wings. keep it simple and cheap and easy to get as possible.

[@DesignYourOwnAirplanes-xd6lz]

I often use XFLR5 or online CG calculators to find the NP and CG locations.

[@billkraemer4710]

I always started at 25% back from the leading edge of the main wing and worked it out from there. KISS.

Only three countries in the world don't use the metric system: the United States, Liberia, and Myanmar. Every other country around the world uses the metric system.
