As an engineer in the field of epoxy composites I must stress, that it is highly advisable to use proper protection gloves, when you handle epoxy. I have seen far too many colleagues with high allergic response to epoxy from earlier skin contact to this substance. Thin nitrile gloves are not removing your excellent handyman skills ;-)
Ditto face mask or vacuum while grinding
@@Jack-ne8vm always, carbon dust is horrifying to the body.
@@index7787 yep
Some time is better to work without gloves but use tool and don't get contact with the epoxid! Epoxid under gloves are so wors! Work clean und Fresh air on the hand/skin is much better. I bought myself a 3M Helmet with extern blower. It's amazing! I've got allergy against different dust. 😑
Hace experienced this on my own skin but still sometimes forget putting them just for the thrill of touching everything 😃😅😅😅
Absolutely amazing! I'm about to build a 1 meter dlg. I wish I had a 3d printer, this video gave me so many ideas 😎
Ok, thank you very much
Very nice! What type of plastic layer do you use in between the carbon and the vacuum bag? Seems like mylar but mylar would have a hard time conforming to the wingtip shape
Hi, mylar 0.25mm
I bet you could mold solar cells on top with this method.
@@CharlesSnyder you can, I've done it. Use thick molds while curing, any shrink or flex can crack panels, but it usually works out.
So this is an instructional video for people who have a full CAD, 3D cut and configured shop?
And absolutely no regard for OH&S
Beautiful fabrication. It appears you have installed the horizontal stabilizer upside down (that is to say, camber curvature on top). Looks like great fun to fly.
Thank you
As someone who builds, flies, and repairs competition F3K gliders, I have a series of questions for you. 1. Why not a bias weave on the wings and tails? The bias would allow for a stiffer part in torsion. 2. Why not kevlar hinges on the tails and wing? 3. Why the 60gsm fabric on the tails? Glass tails are typically fine 4. Why didn't you use 3m77 to adhere the glass LE reinforcements to the core? 5.Why no beds to hold the wings while bagging to prevent warps? 6. Why no shear web in the wings? 7. Why bottom drive for the wing servos? This exposes the linkage unnecessarily.
you have so many questions
@@markoroolaid 😂
@@markoroolaid they're very good questions though, why wouldn't you explain the design choices you made?
And if you later realized you didn't make the best possible design choices, why not admit it and learn from them?
8:30 beautiful moment ❤️ love this aircraft .
A great video, definitely inspired me to give it a try. All the printed bits done in PETG, and will have a go at vacuum bagging when the parts get here.
Quick question: Can you post a picture of the front end? I'm having difficulty working out how the motor mounts to the frame with the m-plate, cone-help ring and spinner.
I really want to know why so many people use chipmunk music on youtube.
😉
What is the weight of your f5k glider ready to fly?
Great build video BUT! No gloves????? Really? YOU can make that choice and risk building a reaction over time but you shouldn't set an example to others for it.
Marko im impressed by your skill level i only just got into 3d printing finding fusion 360 a steep learning curve could you send stl files for fuselarge thx in advance regards Tim from australia
Hi Tim, drawings are here: grabcad.com/library/dlg-style-electric-rc-glider-1
@@markoroolaid which slicer did u take? Cura? Can u give some details on how to print the fuselage? Thickness of the wall? Support. How long it take for u to print all the parts? Thanks
Great build, I'm going to build it. The length of the carbon tube between the fuselage and the stab is missing. Please
This is a bow arrow, 7.6mm
Very impressed. Wish i had skills and tools like that
Would it be possible to purchase one of your F3K DLG electric sailplanes ? It is exactly what i am looking for....
Is that a 3d printed wing joiner? Have you tried that with a DLG launch? I think I would prefer 3d printing a wing alignment jig and using CF/Epoxy to join the wings. Beautiful plane.
yes, 3D printed wing joiner. Printed eSUN CF path filament
Is that 347g including the stand? In my mind that seems heavy for carbon fiber, but I am just getting started and don't know as much.
The plane could always weigh less, but for an electric glider, it is quite ok
What is the opaque plastic? That you put the wax on? You have blue foam, carbon fiber, the coating, and then bag. It keeps the epoxy from sticking to the bag, and leaves a smooth finish.
Hi, this is Mylar sheet
My old neighbor builds and flies these (minus the motor), I've seen him fly one for an hour and a half straight off a single throw once, he competes regularly with them. The craftsmanship of these hand tossed glider planes is on another level, I'm routinely amazed by how perfect and smooth the carbon wings end up. I've always been into flying freestyle drones and would like to get into some wings, though I'll be leaving the gliders alone for a while lol.
Карбон менее гладкий чем скотч
Вы шероховатость материалов посмотрите
did u use carbon Fiber Spread Tow 80 gr for the Wing..? how about carbon fiber 200 gr? is that possible?
in the video, carbon was 60g/m2. It is also heavy, 30g/m2 would be good. 200g/m2 is very heavy for this aircraft
This is such a clean layup, learned a lot from your method/design on the wings.
thanks
@@markoroolaid кстати именно из за этих планеров в f5j перешли на тонкие крылья.
Кстати просто и гениально сделал
Молодец
DLG? “Discuss launch glider” I don’t know how someone would be able to grip that beautiful wing to spin it, and I didn’t see a handle. You did say “style” in the title but at that point just call it a powered glider.
you are completely right
Amazing! Beautiful. I'm curious about building sub-250g models (so I don't have to run the new Remote ID), and it looks like this one is really close! If I didn't need the camera, I could shed about 70g? Maybe scale it down a little?
How may hours did this take? Looks AWESOME!! And how do you keep your work space so clean!
The construction of the aircraft took 1 week, including drawing. Hours about 24h. The desktop must be clean at all times, that's the rule, it's the only way to make beautiful planes :)
The food saver method! Love it, I just started bagging. I use the clothing bags and a shop vac. So far so good 👌🏼
I just made a wing with this method but with balsa sheet for the bottom and for the leading edges and foam in the middle but with normal glue epoxy 🤣I used ptfe boden tube and ran through the foam and put Petg filament through the tube as flexible linkages for seamless single servo ailerons works pretty good I did 3d print spares instead though as it was abit time consuming and im not going through that much effort again what foam are you using seems to cut really good
Hello
Very interesting comment, thank you for that. I used Styrofoam foam to fill the stabilizer and wing filler. It is good to mill.
interbauen.ee/styrofoam-250sl-a-n-80-pakk.html
Great job you are very skilled. You don’t use the throttle stick for flaps? I fly a Vortex and I have the motor on a switch. I have been flying gliders for ever and the flaps are always on the left stick. How many day did it actually take to build it.
The whole project took 1 week
Hello I saw the links for all the electronics but can you also link the receiver? Thanks I loved the build 😄
Hi, I used this receiver futabausa.com/product/r617fs/
It says it has been discontinued
This music is awful but the plane is a work of art I wish I had the tools to make molded carbon fiber wings
thanks
Cool but music choice leaves something to be desired.
Ok 🫣🫣🫣

Great video and great build! I don't get the main wing build though... You cnc'd the foam core top side and put it in a milled bottom part? Can you explain how you got the bottom shape of the profile?
The profile is made in such a way that it should only be milled on top. The leading edge is later modified with a pad of sandpaper from below
Thanks a basic easy building flat bottom airfoil….
Much impressed, great work! FYI, the music detracts from the video.
Hello, can you tell me what sheet of plastic you use at 2.50 minutes to get such a glossy surface? Thank you.
Hi, mylar 0.25mm plastic film
@@markoroolaid Thank you so much!)
hi,Congrats for your job and for shairing your design / built.
May I have the settings for 3d print the parts ? For example : how many perimeters for fuselage 1-2-3 ? and infill density for fuselagerame ...etc
What kind off carbon fiber you use ?
Hi, 60g/m2
I am always impressed with your projects. I love building planes so you encourage me to be more professional in this field and update myself with modern tools like yours. I hope your channel grows more and more and rewards all the good work you enjoy and kindly share with us.

@@markoroolaid lol.... nice glider..
How's the durability of the 3D printed pod? Is the weight comparible with a moulded pod?
If you use nylon CF filament, the strength is super good. It is certainly not as light as making it with carbon and a mold, but at the same time it is very easy to 3D print it.
Would you consider making one in kit form I could buy and give to my.father to finish building as a gift?
Hello. Thanks for asking, but I don't make kits or sell planes. It's just a hobby for me
How much vacuum do you pull with that machine for your wings?
About -0.5bar
Thank you.@@markoroolaid
It's all running at too fast a speed for me to keep up with it.. maybe next time a bit slower instead of whatever speed you are running it at to make the video. I make R/C model boats from scratch but this is all just happening too fast for me to understand what you are doing each step of it.
Thank you for your comment. I'll take that into account in the next video.
What material do you use between the carbon layers, to sand and be able to bend control surfaces?
hi, this is nylon peel ply www.junksupply.com/product/peel-ply/
@@markoroolaid I use peelply as a release material... not as a layer between de CF.. I'll try here. Tks.
Is rutabaga or spectrum better for flying rc planes
How are the control surfaces attached to the wings? is there a flexible layer on the foam that you don't cut?
It's a strip of 45° cevlar
I downloaded the stl files, but when I checked the dimensions in Autodesk Inventor, I found that the parts are huge. Example: the diameter of the motor-mount plate is D770,93 mm. What could be the problem??? Thank you.
I can't tell you what's wrong
The folding propeller does not have a link, what model of propeller is it to be able to buy it, or an alternative.
Thanks
Unfortunately, there is no link. I found it myself in a local model shop and there was only 1 of them there. Sorry, can't help more
@@markoroolaid And what step of propeller and size to buy a similar one?
@@frandalzotto7244 6x4 should fit
Great build! I'm currently building it myself from the CAD files you generously included. However - I can tell that the boom (arrow shaft) is 7.6mm but - how long is it?
cheers
hi, about 760mm
Wait a minute, did I just watch you cut the carbon cloth with a CO2 laser? I thought this was not possible, please explain more If you would!
Hello. I myself also think about whether it will succeed or not. 60g/m2 was not a problem for cutting. I put wet cardboard under the cloth to prevent a flame. i have a 130w co2 laser. parameters were: speed 50mm/s and power 60%. I haven't tried cutting thicker fabric, there might be problems there, but I don't know
@@markoroolaid The 130W is surely helping your cause, Still I am ipressed that it worked. I have tried to cut some 2x2 3k twill with a 60w, no luck. Just a mess.
why'd he censor the word resin?
There was just a typo. Nothing special
Whats the Weight of the wings ?
Hi, about 120g
I have not flown since my college days in the 80s. Your video makes me want to get back into it. I still have my old gear and Aquila glider but a drunk driver put an end to any further flying trips. The area sure looks like the sod farms south of Huffman Texas.
Hi Mongo
I'm glad I can inspire people to build and fly RC planes. That's my main idea, why am I making these videos.
Great build looks awesome😀

What 3D printer do you use?

can anyone explain how he gets the elevator and rudder to work when the wire push rod is so thin, shouldn't it not work because of too much slack? if he uses a spring to keep it tense where and how?
good explanation ruclips.net/video/dH6k7R49tZc/видео.html
Hi Marko, congratulations for your channel and the clean work that you do in all your planes. Would it be possible to upload the fusselage part in other format than stl. I would like to make some adjustment but not possible as I am using Fusion360 and the imported STL as mesh creates too much poligons. It would be fantastic and I would apreciate it. Thanks.

What is the wing area?
Awasome work (and the black mamba is also terrific :-)) !
I've never made a carbon-formed polyester core model, but the quality of your video and the tip about using a vacuum packing machine really makes me want to give it a go. A few questions:
1°) on the leading edge of the stab, do you use fiberglass or peel ply (the material seems to be adhesive) ?
2°) The stab core seems to be made of styrifoam and the wing cores of polyester. Is there any particular reason for changing materials?
Thank you in advance for the time you will pass to reply, and thank to share all your 3D model !
I used fiberglass on the front edge. I tried to fix it with a thin 2-sided tape, but it is not necessary. With the resin stays very well.
Styrofoam is very suitable for both wings and stabilizers. I myself used another material on the wings, because I had it at home ;)
thanks !
Hello Marko, to check :
- for the vertical stab you provide two files, but i don’t see any difference between them ?
- stab is 330 x 81 with 3 mm thickness.
- vertical stab is 233 x 115 with 3 mm thickness.
- wings are 750 x 165 with 10 mm thickness at the emplanture.
thank you in advance for your kindly help.

Never seen carbon fiber like that, nor have I ever seen it laid up the way you did. Are you sure this is carbon fiber and not just something you think is because it kind of looks like it?
It's called "spread tow" carbon fiber. pretty common in the RC plane world.
Spread toe cloth, he's using a really refined method, but it's pretty common in RC.
It's just spread tow textreme carbon, but he didn't lay it up correctly, the bias should be at 45° to the span of the wing for increased torsion strength.
what is the airfoil of the wing ??
Hi. NACA 3414
I would love a slow version and explanation during wing covering process
It looks so impressive something I’d like to try 😊
Definitely give it a try. A very interesting process
@@markoroolaid I’ve got that carbon fibre on my watch list looks awesome now I’ve seen it applied
WOW the wings seem so simple to make???!!
Hello. Exactly, it seems to be easy to do. Actually, nothing very complicated, just difficult the first time
Good effort, but your cutting many corners to make it easy/quick to build. By having a motor it is an F5K class ship, not DLG or F3K. Title is misleading. The build doed look more fun than the tedioue core prep and handwork i do with my models. It takes me weeks/months to finish a model, but i surely get the weight down a lot and stiffness up. Best reference is the Tom Siller build vids, on the alternative video platform.
You are completely right. I just wanted to try this technology. This is definitely not a competition plane. But it's a lot of fun to fly.
Nice build video, shame about the noise in the background.

hi Andy. Vacuum machine for vacuum bag with channels 30cm wide
www.pakendikeskus.ee/en/packaging-machines/vacuum-machines/vacuum-machine-for-vacuum-bag-with-channels-30cm-wide
Downside: You can't heat-cure it. If you e.g. cover the whole setup in a heat blanket the remaining air expands and you vacuum is gone.
Also they aren't that much cheaper than a vacuum pump.

Superb !!!
Thank you very much
Wow! Nice! :)

This really should have been a 45/45 fiber orientation on the wing, not 0/90, since the wing structure is torsion-limited, not bending-limited, and torsional principal stresses will be roughly 45/45. A waste of good carbon, the chordwise fibers here are essentially only contributing weight :/
ok i like your comment, i will use your ideas next time
Great work!
