Thats interesting as I noticed you put the paper on using UNDILUTED PVA glue!!... All the other videos I have seen use 50/50 water/PVA dilution....Perhaps your way stops the paper shrinking by the water??....Thanks....Laurie NZ
Exactly, low water content means less stress on paper when drying. But less water means thick glue so possibility to use too much glue so more weight. It is compromise, but I will rather have slightly heavier build than wrapped wing.
We need to prepare rib template for the cut, and add something to ensure smooth rolling of the wire cutter, glue the sheeting together and ensure balsa grain run parallel to both TE and LE and sand them to same thicknes, cut the slot for aleiron caps, TE and false rib for the tube to attach to, more sanding too. All of that needs properly cut foam core, a build of wire cutter, and a flat surface(flat surface is hard to get)... I am building one, and I could have if it were balsa wing :)
Nice video. I have a balsa Guppy 1 and it flyes like a dream .There are 2 videos here. I want to try your foam core wing. Can you sent the templates for cutting ?
it was regular 80gsm white packing paper and glue was PU foam glue, that will foam during cure, therefore create pressure against negative mold resulting nice finish.
At about 2:37, what kind of paper did you use? Looks like normal white printing paper or was it a fabric? At 3:32you had a translucent film over the wing while it was set to dry. Also what looks like a thin film of plastic. Why? Nice video. I enjoyed watching it.
Very nice! What did you use for covering...That sheet on which you applied glue before placing between the mylar on foam bed? Doesn't look like glass...thanks!
Zárezy do krídla pre nosník je lepšie vybrúsiť malou vysokootáčkovou brúskou ? Prečo nie vypáliť napr. pájkovačkou v tvare prierezu nosníka, či kvôli presnosti nie ? Budem mať zrejme polotovary na L-33 Solo z extrudovaného polystyrénu (rozpätie 2 metre) a rozmýšľam ako tam robiť nosný systém. A poťah je z čoho a ako - prilakovaný ? Ja rozmýšlam nad Vliesom a prilakovať ho PAMLAK-om, čo je lak na detské hračky vodou riediteľný.
I couldn't figure out how to message u but how did u make the foam cutter cause I'm trying to make a wing for a rc shweizer 2-33 that's for my air cadet squadron just message me ur response

I disagree with that. Compared to laser cut balsa, foam core wings takes more time to do, it needs plenty of templates, but with proper foam core building, you can built one straight wing, or incorporate twist equally for both wing. But if you are building more than one wing, foam core is faster than balsa built up, because of the reuseable templates.
Making foam core wings in building process saves a lot of time. A great video demonstrating such building technology.
Suuuper Video 👍 very, very good
I am quite surprised by the answer. I must admit that you have a very professional attitude to the demonstrated bulding technology.
Die Kerne sind super geworden👍🏻
I hope your plane still can fly till today...very beautiful...nice work
+Rodzi Osman She has been sold, but as far as I know, she is still flying.
woow very good job

Beautiflu build , I liked it very much would love to make one like this , is it possible to share all details like plan, electronics used ?
Based on your video I will be using these techniques on my next glider build. Well done.

Nice build sir, love it 👍
Nice video
as cover what material you used and with which glue
thank you
good job and nice result!
Beautiful! Congratulations!
what kind of resin/glue in the bottle? Excellent work!. šikovný chlapec ...:).
Nice ! Very ! Very! Nice! What a freakin nice work! 💙
Beautiful job.
Nice Finish...
Quickly and simply.Nice
Exactly what I want to do. Cheers.
Great job on your video!
that's mean your DIY plane is tough and strong built...I will build one based on your technic shown in the video...well done..
In therms of weight, how does this compare to balsa?
I don't really have acces to balsa wood, and i will try to make full foam glider.
Could you send me material list about covering. I just try produce UAV and being hesitant.
Hello ! gwhich is the material you use, the transparent.
you have a great idea about the construction of the wings. very well.
Great job dude !!

excellent work
great video if you made the fuselage yourself cany you share a video about it.
what was the paper and glue ? please.
it was regular 80gsm white packing paper and glue was PU foam glue, that will foam during cure, therefore create pressure against negative mold resulting nice finish.
How does compare to the original wing ?

That is awesome! subbed
Wow.
Thanks. This video help full 😊👍🏻

Which airfoil do you use? Tq
What paper you use?
Why didn't you just use the wire to cut the spar?
Hello. What density is that foam?
Hi, just normal EPS or XPS will do the trick. EPS is lighter but XPS is stronger.
Which type glue used
What type of paper are you using ?
这是怎么做到的，感觉好厉害
paper saturated with wood glue? Thanks
What kind of music is played in the movie?
you have the bluprints?
well done
I want to know how to make it
At 5:00 what is that thing you put on your drill to make the hole for the servo?
+Felipe Forlin Hi, it is high speed grinding dremel
šikovný chlapec ...:)
Alguien podria decirme que material y pegamento usa para forrar las alas en el minuto -3:56
@ Scale Soaring
End weight?

what is that foam and where can i get it?
It is normal EPS foam.
+Frank R. Pilot It's styrofoam. You can buy sheets of it at many hobby shops or online.
I disagree with that. Compared to laser cut balsa, foam core wings takes more time to do, it needs plenty of templates, but with proper foam core building, you can built one straight wing, or incorporate twist equally for both wing.

Y los planos?
Dirty work....
