Building the ‘Black Mamba’ RC Electric Glider from Scratch: Carbon Fiber, 3D Printing, and Flight!

[@dougturner2036]

Not only do I envy your building skills... your ability to see a project all the way to finish while keeping your workspace so clean is mind-blowing.

[@fierceflyer5]

Not only having all the machines but having the skills to make all the CAD designs is highly impressive. As are your building skills and attention to details.

[@wayneewing4072]

Your ability and craftsmanship never cease to amaze me!

HI ! Marko ! at first I'm crazy about glider ! but this one it's a master piece ! black mamba it's the right name for this beauty ! well done my friend ! 💙

[@k.o.0]

Next level fabrication! Beautiful build! Always impressed with your design creativity and build finish. Keep it up!

[@OffGridOverLander]

I never thought of using my laser cutter to carbon, love it!

[@tonyhallen1062]

It is amazing how rigid the airframe is. By its appearance one would think it would be frail but the shot of it landing shows how strong the build is.

[@ianreed4636]

Pretty amazing!! You definitely have a wide variety of equipment an knowledge.

[@SebastienChedalBornu]

It's funny how you configured it like a plane. Usually motors are option on gliders so we put motors on a two or three position switch because you generally want to climb not to have little throttle. and the throttle is used for airbrakes/crowbars this way we have full control of the speed. But really nice réalisation thanks for sharing and for the build/tips

[@coriscotupi]

It's a matter of personal preference. I like to have the motor on the throttle channel, and airbrakes on two or three position switches. But I get it that not everyone enjoys this configuration.

[@markfisher8943]

Great video. I’d like to pick your brains on how you’d put curved dihedral into that wing? I’m amazed the Mylar sheet conforms to the compound curves so well. Beautiful work.

[@MarkoRoolaid]

Hi, You can curved dihedral into that wing, only if there are genuine molds. This is not possible with similar technology. Mylar does not stretch or bend like that

[@AcroFpv02]

terima kasih atas ilmunya ❤ im from Indonesian

[@EMTAx]

[@MarkoRoolaid]

[@marcelpieterse1]

Marko, In the video you connect the main wing, one site is on the table and you meassure de height from other wing tip to the table. How far from table to wingtip in cm…..Greetings.

[@MarkoRoolaid]

hi. 22cm

[@GWAIHIRKV]

A beautiful build. Just a thought, might need to be careful on a hot, sunny day? There is a reason the full-size are always white. . .

[@paulomr445]

What kind of laser cutting machine are you using at 1:32? I was under the impression you couldn't cut carbon fibre with a laser, and if you did it'd make a lot of fumes. If it's CO2 what are the settings?

[@MarkoRoolaid]

Yess it is a CO2 laser. In general, you can't cut carbon, but since it's very thin, you still manage somehow. I put cardboard moistened with water under the carbon cloth to prevent flames. Speed ​​20mm/s, power 100% 130w

[@DerEumel-oz3jw]

How do you manage to keep your workbench looking like new in every video? - For me, after working with resin 2-3 times, it always looks like after the war

[@MarkoRoolaid]

😂😂😂😊😊😊

[@SebastienChedalBornu]

On grabcad you provided x_t files for the foams. Can you provide step files too so we can ipen in several tools? Thanks a lot.

[@marcelpieterse1]

Marko, can you share the G-code file from wing and vtail for cutting the foam….😃

[@mikemolto3447]

Excellent design skills and valuable craftmanship! Why did you place the 25gr glass layer on the foam surface instead of facing the mylar?

[@MarkoRoolaid]

Hello. Thanks a lot. Why did I put the fiberglass like that, I thought it was better that way :)

[@LUKAS-BERKA]

Hi how big it is ? 100" ?

[@MarkoRoolaid]

hi, 80''

[@mlentsch]

p.s. Nice radio, but it needs a RadioMaster Ranger module on the back. They've got glider receivers with vario, too.

[@MarkoRoolaid]

The hinges was made of peel ply material. link too www.grs.ie/product/peel-ply/

[@filipporossifavilli68]

beautiful construction congratulations....I wanted to know how much power does it take to cut the carbon fabric??...

[@MarkoRoolaid]

I have a 130w laser and used 100% during the cut. Speed 40mm/s

[@qfudgedoggy]

Beautiful work! Been out of the hobby for many many years but I was doing this same construction method, minus all the CNC stuff, 30 years ago. Never could get the finish on my wings to look as pretty right out of the bag though. I found over time I had problems with the carbon fiber delaminating from the foam after several years in storage. Is this a known issue and what is done now to keep that from happening?

[@MarkoRoolaid]

Hello. Quite an interesting problem. At the moment, I have not had this happen with any aircraft, so have not tried to find a solution to this problem either

[@stewartkeeble2371]

Beautifully made great job. Can I ask do you sale these in kit form or ARTF so to speak..just wondering 👍👍

[@CanCui-en3hd]

wher to buy the vacuum pump and the plug on the vacumm bag?

[@MarkoRoolaid]

Everything is done by myself.

[@VIJAYzk]

will the foam comptress in the vacuum baging process?

[@MarkoRoolaid]

surely a little bit of foam will be compressed, but luckily nothing significant

[@윤태경-u4l]

Your skills are truly impressive. I am also planning to build a glider using carbon fiber. I used the 3K carbon fiber I have for a stiffness test. Like in your video, I made a single layer, but it was not strong and bent very easily. How strong and flexible are your wings? If I had made it, the wings would have broken during flight. There is no place to learn carbon fiber work where I live. Do you plan to make a detailed video on carbon fiber work?

[@MarkoRoolaid]

Hello I myself try and experiment. In terms of power, the Black Mamba is certainly not a Hotliner, but still a thermal glider, which means that maneuvers must be done with feeling and not overload the plane. Since I see that there is a lot of interest in the carbon of airplanes, I will definitely make more detailed composite videos in the future

[@SebastienChedalBornu]

I'm curious, what is your laser cutter ? CO2 or fiber?and what power ? I thought we couldn't cut carbon fiber with laser as for example you can burn carbon rod but only epoxy will burn leaving the carbon fibers

[@prestonengebretson5043]

It is likely a Fiber Laser, as we have a 100w CO2 and it will not cut CF cloth. Let's hope he answers.

[@MarkoRoolaid]

Yes, I use CO2 laser 130w. max cutting power and speed 40mm/s. only thin carbon fabric can be cut, up to 80g/m2. 200g/m2 fabric definitely won't cut it anymore.

[@SebastienChedalBornu]

@@MarkoRoolaid thanks for the information. I'll try with my 80 watts CO2 cutter

[@spiroskatsikas]

Great job but I would hope u learn to put aileron control inside using a carbon fibre rod with horns inside the fuselage ❤good work always watching and learning, I don't have the machine you have, I do everything without printing or laser cutting 😢,

[@Bagnistefano]

Great ! I am following another maker and video maker. For each step he add an explanation in writing on the video. It'd be useful because I lost a number of procedures. As an example how do you get the flap hinges already made in the cast ? Or what is the foil that you put over the carbon ? Till now I just saw the carbon and the resin bagged with no other laminating aid. I subscribed to the channel,I am tryng to keep moving since I was born with balsa and paper foil,not even the Oracover.

[@jorgarciahern]

Hi Marko, great job again, you make it seems easy. Some questions? Any wax on the mylars? You always build flat bottom profiles, does it influence the flight performane?

[@MarkoRoolaid]

Hello. I also used mould wax, but it may not be necessary. Why do I make a lot of wings right from the bottom? The main reason is that it's easier.

[@jteddy11]

Please wear a mask when cutting carbon fiber if you do not already use one. I am sure you do wear one, but I could not watch this and with a clear conscience not state how harmful carbon fiber is to the lungs. Beautiful build.

[@RCjunkie]

Love to have your CAD skills. I can draw in 2d all but not 3d

[@grumpyoldnerd8727]

the craftsmanship is astonishing. But I cannot understand why you didn't completely hide the control hardware for the ailerons. It is possible, even with low profile wings like that

Tere, Marko ! väga hea töö .. mulle väga meeldib just wanna ask, would it still fly if I rescale the wings and tail ? I would like to reduce the wings size from 1m to 0.5m .. is there anything to consider ?

I'm afraid it may not be that simple. The wings may remain too thin, and the fuselage too narrow for the electronics.
