- In this video, I'm showing you Part 3 how to make a 1m #F3k DLG . This is a foam wing core final prep video.
I cover everything from cutting of the carbon fiber and fiberglass cloth to the final wing core prep.
If you're looking to build your own #rcglider , then this is the video for you!
In this video series, I'll show you everything you need to know to build a 1m #DLG scratch build.
Thanks for watching!
I've left a link below for you if your interested in all the files for this build.

Awesome work! It looks great!
thank you very much. Appreciate your thoughts my friend :) Hope to see you flying soon!
Good stuff indeed.. If you don't mind me asking, where did you get your mylars as you referred to them. Any help would be greatly appreciated. ** UPDATE **, I see below in the comments you answered this already, Eplastics.. Thank you...
no problem. Just make sure you get one smooth (glossy) side. Directly effects final finish :)
@@amonus-air2160 Thanks and yes, I did.. I had them also cut the sheet into 8" wide strips at 4' long for a total of 9 strips... yeah! BTW, what viewer is to be used for the .DAT files?
Thanks again,
DJ
I use Notepad++ to open the .dat files. So, you go to Airfoiltools.com and :
1) choice my airfoils
2) add a new airfoil
3) paste in .dat file numbers.
4) open in plotter to input chord length (I usually add a .5mm halo for cutting wire waste)
5) print out the .pdf and use to make your templates
:)
@@amonus-air2160 Thanks again for your help on this...
espectaculat trabajo. aprendiendo para poder hacer el mio. saludos
Muchísimas gracias. Le deseo todo lo mejor en su construcción y feliz de que le guste el proyecto.
I love this series I e wanted to DLg since I was little but DLGs cost a small car …even today I can afford one but they are rare so I’m going to take a leaf from my Var-Eze experience and make me one
glad to hear you are doing your own.
I like so much this video series. It's very very clear.
Being french, I didn't catch the name of the glue you use to stick the nylon hinge on the core ? Please !
Merci pour vos gentils mots, et la colle s'appelle adhésif en spray Super77.
@@amonus-air2160 ah ! Ok
It's the same 3m 77 spray 👍
@@freedom2000 yes, and you don't need much
one other thing, if I did this again, I'd put the hinge on the bottom
@@amonus-air2160 is there a reason ?
I saw many gliders with ailerons hinge on top and flaps hinge on bottom.
Mainly due to increase bottom angle of flaps.
But ailerons mostly go to the top when in motion. So hinge on top seems perfect ?
Where do you buy the .75mm Mylar polypropylene? Everything else looks doable! I hot-wired as a teen, but of course it was all pulling the wire over the templates by hand. But man we flew those planes for EVER. Such great memories. Would love to step up my game now that I have kids who I'd love to show this stuff to.
Hi. I searched everywhere for this, and finally found at a company called "ePlastics"
Only thing to address is to make sure one side is smooth, not matte.
Cheers! 😎👍
@@amonus-air2160 OK amazing! I will check that company out thank you very very much. That will be perfect! I hope your day is going wonderfully! Thank you for the wonderful video content and happy flying.
How is that carbon fabric described? I have tried to buy that fabric but I'm not buying the right stuff. I want to be able to harvest those strips from it. I looked up 12k tow on amazon, but all I see is carbon fiber twill weave. Where did you buy it and what was it called?
Thanks so much. David
so the CF fabric is described as 12k 200g UD Carbon Fiber Fabric Unidirectional cloth.
I buy all my CF from Aliexpress as they have the best prices if you don't mind 2-3 weeks shipping.

Thanks for subbing!
Nice job! Are you sure that is Mylar and not polypropilene?
yes, it's polypropylene. Everyone still refers to it as mylars though, old habits :) Thanks for the comment!
@@amonus-air2160 is Mylar still OK? Searching today I found the roll of "Mylar" I have from the 90's. It's ~13.5 thou, .34 mm thick. I bought it back then from a guy who was molding wings but never got around to doing it myself. Would it still be legit? It seems mighty smooth. I'm thinking it could still stand a bit of thinning for the LE profile too. (I also found my light cloth (still not sure of the weight), so getting closer ... need to get the CF)
@@AndrewMoizer Hi my friend. I've sent you an e-mail with some additional info.
Does the pre-preg actually saturate with wet epoxy?
technically, I don't think so, not 100%. But I believe letting it sit in fresh laminating resin improves it's bonding.
Thanks for the question.
Where about in Canada are you?
I'm in Ontario
@@amonus-air2160 oh yea. I'm in Alberta but originally from BC
