i see your being cautious about the fiberglass dust, via the mask, but your still leaving that dust to be kicked up and breathed in later on, id consider having a shop vac running to pick the dust when you cut/sand. or getting tools that have the vacuum hose attachment built in.
Even just a box fan blowing out of an open window/door will cut down on dust immensely. My shop fills with dust when i sweep, sometimes its so thick you can see it blowing out through the fan
The ekranoplan project was top secret. It was called project steamboat. At the time, there was a death penalty for mentioning ekranoplans outside the factory. Nice trick with the Mylar to make the fiberglass smooth.
Oh yeah, the ASA Aero is pretty nice stuff. I think it is more suited for Vase mode models tho, it really strings a lot on normal prints. But nevertheless your Caspian Sea Monster looks amazing, can't wait to see the next episode!
*Building and Testing an RC Model of the Caspian Sea Monster Ekranoplan* * *0:03** Introduction:* The video outlines the ambitious project of building an RC model of a Soviet-era Ekranoplan, similar to the Caspian Sea Monster, using various techniques like 3D printing, hot wire cutting, fiberglassing, and CNC machining. * *0:14** Project Goal:* The initial goal is to create a functional ground-effect vehicle, with potential future development into a test platform for advanced surface drive propulsion methods. * *0:42** 3D Printing:* ASA Arrow filament, known for its foaming properties that result in lightweight yet durable parts, is used with a Bamboo Lab Carbon X1 3D printer for various components. * *1:36** Wing and Tail Construction:* XPS insulation foam is hot-wire cut for the wings and tail, reinforced with carbon fiber tubes and Gorilla Glue. Packaging tape is used for control surface hinges. * *2:20** Tail Reinforcement:* Due to the tail's initial flimsiness, a significant amount of reinforcement is added using fairing compound and carbon fiber, although this is noted as overkill for a tail with tape hinges. * *4:01** Wing Composite Skin:* The wing is covered with a composite skin using 2 oz fiberglass and a Mylar film technique for a smooth finish. A Kevlar strip is used for the aileron hinge. * *7:04** Fuselage Assembly:* Multiple 3D-printed sections are joined using carbon fiber tubes and Gorilla Glue to form the fuselage. A custom latch mechanism is created for the electronics access hatch. * *8:24** Motor Mounts:* Four motor mounts are 3D printed using ASA Arrow material. The mounts incorporate thrust vectoring flaps controlled by servos. * *9:21** Fiberglass Reinforcement:* The 3D-printed fuselage is reinforced with a layer of 2 oz fiberglass for added strength. * *10:35** Tail and Pontoon Installation:* The pre-built tail section is attached, and 3D-printed wingtip pontoons, waterproofed with epoxy, are screwed into place. * *11:05** Electronics:* A Pixhawk flight controller is used for motor and servo mixing, utilizing a significant number of its output channels. * *11:51** First Test:* The model looks impressive but struggles to take off from the water, exhibiting difficulty turning into the wind. Water ingress into the 3D-printed parts is identified as a significant issue. * *14:15** Second Test:* After addressing some water ingress issues, the second test reveals the plane's reliance on par thrust for takeoff. Without it, there's excessive drag, preventing it from lifting off. * *15:32** Further Adjustments:* Additional paint layers are applied to improve waterproofing. The plane's tendency to pitch up and drag its tail during takeoff is identified as a major problem, potentially due to a low wing angle of incidence and lack of flaps. * *17:49** Future Plans:* The next steps involve improving the ground effect performance and incorporating a high-speed paddle-wheel surface drive system, building upon a previous project. * *18:06** Filming Technique:* The smooth video shots are achieved using a Freefly Movi Carbon 5-axis gimbal. I used gemini-1.5-pro-exp-0827 on rocketrecap dot com to summarize the transcript. Cost (if I didn't use the free tier): $0.03 Input tokens: 21910 Output tokens: 723
7:06 those tendrils that keep growing and dropping off to the side. are they because of ASA being difficult to work with, or what were your settings? I don't have experience with anything other than PLA, but they somehow don't look right. on the other hand, it is a big print, with my ender 3 pro, this looks like 48h plus. I understand, if you pushed the limits on that one.
That thing looks so nice. Autonomous caspian sea monster missions would be so sweet but it sounds like the EDFs are too power hungry to do anything long distance like that.
I used to built uncontrolled ekranoplans (to slid along the road) in various forms and sizes. From my experience I would say your wings are way to shallow to create any sufficient air cushion to ride on without going very fast. I would recommend to mount the wings higher or to give it steep flaps and bigger floats, that way you can also start with less drag on takeoff since the fuselage is outside of the water. The aerodynamics for this don't scale well with the 90m original.
Interesting to see the high take off speed with such a light craft. Especially the scale speed will be huge. Does the specific aero work much better at true scale? One thing that comes to mind is that the flight altitude was never high. A tiny fraction of the whole thing, so you need's ultra low chop, basically a gym floor.
I worked on a assembley line one time and when ths things got boxed and taped it went thru this taper that heated the clear packing tape up as it layed it dwn it activates the sticky on it were itll stick a whole lot better
on the topic of using mylar sheet to make wing surface super-smooth... I actually wonder, do wings with ultra-smooth surface give better lift/performance compared to wings with very slightly bumpy/textured surface all over? Asking because fluids can behave a bit weirdly with ultra-smooth surfaces, and at least underwater, most/all aquatic animals (fish etc) do not have hypersmooth skins, but rather textured ones. And iirc olympic swimmers use swimsuits with slightly textured surfaces.
This might be an odd question for you. I'm currently in a prototyping stage for a 3D printed B-1B Lancer and want to have 4 engines on it as well. Any chance you could tell me how you got your 4 EDF setup done? I haven't been able to find any good documentation on the topic. I see you used a 4 in 1 ESC, do you have any brand recommendations that have served you well?
Why packaging tape for hinges? You could get a more sturdy tape with better glue and cover the other side at the actual hinge with another layer of take to make it even stronger and non sticky. But I'm not a builder, so I can be wrong.
You should angel te edf‘s a bit done to get the airautomaticalli under the wing and maybe make it waterproof by using dichtol cps drones made avoiding about it
You’re not achieving very good strength with the Bambu Labs’ max 50C chamber temperature. A Qidi Q1 Pro, with its 60C chamber temperature, will do a better job for a third of the price.
To get the water out...build a vacuum chamber in which the craft can rotate so the water find the holes? Just a cages, a plastic wrap and a vacuum cleaner might do it.
Thumb cut... LOL literally! Love your vids but man you should read through your overdubs a few times. They sound like a 6th grader reading a book report.
What you are doing is very cool man. Also this guy shows how to get good finish on complex geometry without vacuum, th-cam.com/video/4nJflA1HpkA/w-d-xo.html

8:28 The front engines on the Caspian Sea Monster were used only for takeoff. Once airborne, it could sustain itself on the 2 tail engines alone.
Proportions of the wings do not really work on such a small scale.
Bigger wing and lidar controlled pitching can be the key. Will see in pt. 2
Love it when you cut off your THUMB!!! 1:53
I stopped and went back to make sure I saw what I saw.
am i tripping???
No worries, it grows back.
You are solving every single problem the Washington state ferry system is facing right now. Game changer. Kudos 👍🏻
🤣🤣🤣 And creating a fresh new batch of them!
The rolling shot at the end was such cool footage!
Bro how the hell you do these so fast??? Its like a new project every 10 days god dayumn, you are so good at it.
No lie, it's amazing how great the projects are and fast they are accomplished!
Looks amazing.
Those tracking shots were incredible.
One of the best doing it.
Thanks.

Only 1 thumb is really necessary for a successful life, might as well melt the other one right off 1:52
Your videos are GOLD!
Love your projects rctestflight always learning and fun at the same time

The car mounted camera flex at the end was nice
Best videos on the internet, especially if they have a shanty, Daniel, it's been a while, shanty when?
Выглядит шикарно 👍
18:00 cool shots
I wonder if some dihedral might help. Might get some lift a bit earlier and balance it from that tip to the right we were seeing
I have done the same project before 2years and nice to see it again 🎉

This is such a cool plane, looks so good, like the original one. 👍💪✌
My favorite video is the one where you tested the milage of different rc cars❤❤
7:06 those tendrils that keep growing and dropping off to the side. are they because of ASA being difficult to work with, or what were your settings?

That thing looks so nice. Autonomous caspian sea monster missions would be so sweet but it sounds like the EDFs are too power hungry to do anything long distance like that.
I think a surface drive would help with that.
Love your content!!
This video starts out just like "The Truman Show."
Those cheap collapsible fishing rods are ideal for RC boat and seaplane retrieval, with a weighted float.
Love your work❤❤

1:54 not the thumb!
I think adding some weight in the front should help since it’s already underpowered, try to remove some weight from the back

One thing that comes to mind is that the flight altitude was never high. A tiny fraction of the whole thing, so you need's ultra low chop, basically a gym floor.
Does its movement match the real thing?
Have you tried making a srn1 do the same thing
Beautiful craft
You just got one Social point stripped off by Zelenski, for glorifying Communism 😂😂😂

hi ckfpv, have you become a flat earther yet? If not I suggest watching _Level with Me (2023)_ by Hibbeler Productions

Amazing job. Hope you learn from this project and print parts with solid walls. I use large nozzles like .8
I was waiting for this video!!!!
6:54 HACKSMITH MINI LIGHTSABER
If you happen across any lift/drag data for the real thing or your model I would be very curious.
The natural next step
i already watched the whole video
Ok
The thumb cut was a nice touch. lol
WHEN ARE WE GETTING ANOTHER GWEN FPV FLIGHT
Flaps? To help 😊
Add a motor to the undersides of the tail? Instead of ruining your front profile at least.
It looks like the plane might benefit by mixing in a little elevator under power to keep the plane level 🤷🏻♂️
ACE!!!!
"just like paper mache - just more carcinogenic" LOL..
Which part is carcinogenic
good man
Draggin ass with style
Oh hellz yes
might want to cover your licence plate
YESSSS, FINALLY
Hi
How many of these Projects do you have lying around your house at this point? 😂👍
When the camera and gimbal cost more than the car.
