18:35 well you might as well club it to death since its inhumane to let something suffer 😂
Lmao, now I know your true intentions. We'll fix it for future missions! Until then, it can suffer in silence.
Oh no, yt doesn't show your comment in the top ones because it's so violent I suppose lol
@@CPSdrone good ol youtube being dumb
@@CPSdrone ZAUWAZYLEM ZE WY W POLSCE
You should try toridal propellers and see how much faster and longer the battery runs
Argh, those poor propellers, mangled by saws. I Was hoping you'd put a cover over the nut, to keep the trailing edge shape, as you'll lose a measurable amount of performance with just the bare nut.
We might try that. It would be interesting to see how much that one factor will improve the speed.
I kind of doubt it. Sharrow propellers are probably the highest performance outboard motor propellers they have the same open trailing edge design
@@Neberheim That's because there is exhaust coming out of them. There is no exhaust coming off the back of these propellers, thus it would help to have a cone. It was the first thing I saw that they could improve.
Love how modular it is. It's great to see how much fun you are having creating and testing it.
Awesome!
Zajebiście się to ogląda !
Congrats guys that video was so entertaining ! Keep it coming and you're gonna succeed a lot :)
Brilliant!
Fantastic video!!
Dopiero po scenie z uniwerku ogarnąłem że jesteście z Polszy xD
Pozdro i gratuluje zajebistego kanału!
No, mnie też zaskoczyło gdy usłyszałem język polski, a później zobaczyłem polskie napisy na basenie.
I really enjoy watching the video
as soon as he played sans theme on the motor I subscribed. Love undertale.
All I ask is make more megalomania references in the future! :3
fajnie sie bawicie chłopaki 🔥
Only watched a few of your videos sofar. But I'm super excited to join the course as fast as I can afford it! :D
Until then I'll continue watching these videos. :)
Print it in 95A TPU maybe with at least 1cm walls (on the areas that will crash)? You can solvent weld and smooth TPU with THF. And you could leave room to slide in some sheets of polycarbonate. Then it would be hella tougher. Nice work!
Love you guys lol
seeing what speeds you reached with what kind of electronics actually makes me respect some old toy rc boat I have more.
it was a old rc boat that was mostly a rc speedboat, but also could go underwater and stay just below the surface.
that old thing had a basic brushed motor, based on how long it could work on a single battery it would use around 30 to 100 W in total for the entire boat.
the motor just had a long axis on it which went trough a insane amount of grease just like vaseline to make it water tight, then at the end there was a small screw around 2 cm to 4 cm diameter or such.
the speed on the water was 12km/h. underwater it would go at around half that speed, this was also largely due to the diving actually working by just flipping a rudder to steer a part of the motors force to force down.
however while it also sends out quite some water it doesn't seem as extreme and powerfull as the motors you used, which is weird since according to that it should be slower instead of faster, but perhaps the streamlining of the boat. or perhaps the rpm might be part of it, or the general efficiency of the propellor and such matched to the speed or other thigns to reduce turbulence in the water since that boat seems to have a lot less turbulence than the motors you use in this video, the amount of water seems less extreme but much more in a straight beam.
it would be interesting to see what happens. that boat is broken now, the motor and propellor still work however.
but in my case I wanna try to figure out some kind of small energy efficient motors to use to strap on braces on the arm or on a surfboard or such, but probably more on something like arm braces so it is kind of like a submarine but then you are the submarine yourself, that would probably feel great, kind of like floating since you are as good as weightless yet still would move through the watter as if you are gliding.
You guys really need to build a wireless or bluetooth remote programming setup, so you can re-program the ESC's externally instead of having to open up the case every time
Its obvious that you two are true games & programmers: changing the ESC startup sound into megalovania 🤣. I'm proud of you guys.
Also what other upgrades/ mods might be in the pipeline? Really looking forward to them 😁
Thanks haha. Right now we're working on a CPS 6 (6DOF) design, which means that it moves in every direction as opposed to CPS 5 which doesn't move side to side. Then, we'll be upgrading that one 😄
@@CPSdrone awsome to hear that. Sound pretty cool. But what would that mean for the course? Will CPS6 be included in the CPS5 course?
@@glenndhooge6787 Yes, the course would be updated. But don't take it for certain just yet, we might for example do a simpler CPS version first. We've just starting working on it :)
mega dobra robota! Właśnie zabieram się za motorówkę i szukam materiałów, ale teraz chodzi mi po głowie łódź podwodna xD
Enjoying the videos👌
great job guys, have you consider the toroidal propelers? and you can print them...
Really cool!! I was wondering how you managed to avoid corrosion of the motors??
Hi @CPSdrone
Love the project! 😻
Cheers
Evel-Knievel ✌
Thank you so much!
really good video
Naprawdę mega bardzo mi się podoba dobrze się ogląda
very cool project, I think if you put a mini speedboat turbine it could be fine faster
We have a model building club here in town.
They participate in boat racing competitions and they are using way smaller screws.
Actually, what you should have done is meassure the voltage and current to figure out if your power is restricted by the battery or if your esc is at the limit.
Then use a number of differen screws to optimize the setup.
A static setup in a bathtub will only tell you so much.
Covered soft skin is a good idia for protecting drone. Also waterproof camera for rescue mission.
Yeah, some bumpers would help!
Мне кажется в воде нужен формирователь, как у вас в предыдущей моделе, в воде вес мене важен. А вот энергия когда сформирована в тоннель мне кажется будет эффективнее. Ребята успехов, жаль у нас так интересно не было)
Such amazing efforts guys, but i would love to see more solution on the cooling for ESC
If I've understood correctly, it is not in direct contact with water but inside that electronic tunnel.
Make it waterproof by pouring epoxy on it, then take it out of that tunnel and take profit from that free best watercooling you will ever get.
One easy fixe would be a bigger esc, as there are others able to handle 80A without overheating.
It would be lovely to see the drone fitted with toroidal propellers to get a feel for performance differences.
how have i not found this channel before?
Super panowie !👌
Dzięki!
@@CPSdrone Studiujecie w Gdańsku czy gdzie? Czy sami z pasji?
I really enjoy your video, I think it might be better to programe different speed level might be fun
do you plan to switch to wireless communication in the future? I
Can't wait for your next video !
excellent! I hope to sponsor the motor and ESC for you.
I know all modern propeller designs mitigate cavitation, but Id like to see a propeller design that incorporates the effects of super cavitation to help drive the propeller and form a caveatting bubble around the propeller.
Maybe multiple small very very small propellers is the answer.
i love using hooktheory!
Ha, I use the same 50a ESC on my planes, they're tough but noisy. GG
Super job guys, and fun video. That's a pretty small ESC for such a motor, I would have expected a 50-60amp with a thick heatsink. I think you should test this again in a larger pool and you'll probably get over 4m/s. I can't help but feel that you need to make a proper fan duct to get that speed. As for the leatherback turtle, I think there's probably more to that speed. Like it needs to be in a current.
The heat actually dissipates really fast without a heatsink. I think for anything more powerful I'd be just easier to somehow put ESCs outside the electronics pipe, in the water.
A motor hub/duct would definitely improve the speed, but also the props weren't centered perfectly.
You're right, leatherback turtles are suspicious, we need to race one. It needs some turtle-proofing though, so that neither the turtle or the drone gets hurt.
@@CPSdrone I wonder if it is worth considering a prop with a built in duct housing. Like the ring around the prop. That does add weight, but not as much for marine props. It would hopefully reduce turbulence and cavitation.
I hope you make a more protected cover for the motors (like before)?
I find it awesome that this guy uses OpenVPN :D
I have such an idea for a safety system against losing the drone due to entanglement of the cable. Hardware - Cable cutter, standard co2 cartridge connected to an inflatable balloon, e.g. made of latex, something like a condom. Soft is a simple instruction. If the drone has tangled the cable under water and it is impossible to get it out, the cable is cut and the balloon filled with co2 floats to the surface. Cutting the cable and opening the co2 tank requires strength, maybe a mechanism based on the action of a screw.
Not only are you two brilliant but you’re so handsome, it’s unfair 😩 love the videos!
It's the tether! Making it difficult to to control when below the surface
Green sea turtles are actually very fast swimmers, recorded up to 15 m/s but only in bursts as they need to breath air.
the intro with the turtle comparison with michael phelps🤣 🤣
Very cool project. But what are the material costs (ballpark) for building cps or cps s? I couldn't find that on the website.
Panowie pełen szacun, sub i łapka up
Theres someone on TH-cam that makes a fully 3d printed "jet boat" using a motor like a jetski, sucking in water and shooting it out the back even better achieving 13ftlbs of thrust! Once you find it and see how small it is just 13 will be understood why its so fast.
Hello. Fine job. You are probe a discoidal submarine drone?
Try a vertical stabilizer on the top and bottom so it doesn’t slam the wall and if you make them actuate it’ll be more maneuverable
Smoothing the body of the drone would improvebits performance significantly more, also giving it a spear head tip alike to break the water
Ale że Polacy takie coś robią... Gratulacje
I’ve always been curious about how one would go about waterproofing stuff for underwater projects. I was also surprised to see that the motors work submerged. Can someone explain how or what parts need to be waterproof?
saludos desde Colombia me encanta su proyecto ,,ya pedí todo los materiales por aliexpres ...pregunta en su curso ,,,hay la posibilidad de que programen mi computador portátil a distancia ya que no se programar ...
Really beautiful video keep going! if you want to increase speed you need to improve hydrodynamics. Any protrusion (especially if of a small surface area) creates a large viscous drag (it is related to the Reynol number).Try to reduce the small surfaces and improve the hydrodynamics of the engines by adding cones.
Thank a lot for the tips! That's exactly what we want to do if we ever make it even faster - start with a smooth teardrop shape outer shell. But that will require way more changes in the design.
Viktor Schauberger’s impeller design the ultimate.
Along with his plow and countless other inspired by Nature designs that all are best of the best.
Always look to nature in design
very good and interesting to see some people on youtube video's who make their own electronic things but then that it actually works properly instead of being mostly waste, and where high power expensive parts are actually the high power expensive pars a semi-average person would be capable of getting instead of that other half where of youtubers where for example only the esc already costs close to €1000 and the motors something like €800.
there are some great optimizations still however, but will talk about that in my other comment.
I advise you for Loop propellers 3d can faster of that old propellers. Or you can test your own customized propellers can faster or not. 👍
polska górą!
fajne to macie chłopaki i ta megalovania xD
16:49 подождите, мне послышалось, или он сказал "так-так-так"? Это даже подходит по смыслу к "that's right".
18:24
И здесь))
So we have this Autonomous Underwater Club at our College (MTS AUV ZHCET) , and we are struggling to build this kind of stuff. How you waterproofed the motors?
Hey, I might be able to help. Do you know the Kv of the motors you used? This situation definitely calls for the lowest KV motor you can find and at least a 4S battery. It will be far more efficient because you will be drawing far less amperage as well so everything will run cooler. You will sacrifice some runtime potentially by having to use a larger battery but due to the overall efficiency of the low KV and higher s rating it might actually run for a longer period of time. Anyway I'm about to buy your course and build one myself! Awesome work
Usłyszałem ze chłopaki z Polski i az wykupie projekt :D samemu tez sie zabieram za taka zabawke :D Pozdrawiam.
What software did you use?
Twoje filmy są świetne. Zastanawiałem się, czy mógłbyś zbudować ogromny statek towarowy RC
i have the same powerbank that you can see at 12:34 lmao
Amazing project guys ! It is really well engineered! Can't wait for your next video :-)
Thanks, us too!
could you tell me pls which esc did u use?
5:21 I hear Poland!
A question... How can this engines work under water without watertight protection... No short circuit?
You guys are freaking awesome!!! My grandson and I love this stuff. He’s 11 and I’m 65. We might build one for his next science project. We have a question- why. are you guys calling it a drone when it is an ROV? Thank you
Thanks a lot! You can also call it an "underwater drone", so we call it a "drone" sometimes
Gdzie kupiliście te silniki? @CPSdrone
Hi
Wich motor do U use for forward drive (Them in/under water?
Thanks
Torben 🇩🇰
👍👍
Класс !
Своего добились ! Вопрос , новые электро моторы как нибудь защищали от воды ?
i didn't know fred has a new channel
You should cover the motor
13:53 Gotta love Oscar Liang's website.
what 3d printer brand is it?
Jaki silnik używacie ?
Can y'all explain how you're water proofing these quad copter motors
Motor case exposed to waster causing drag
Those motor are water proof?
when you make mark 3 and it goes even faster, Those motors better sing E1M1
Fajne
In my personal experience sea turtles can haul ass when they choose! Not at all surprised to see those burst speeds. Some species of sharks (e.g. tiger sharks) prey on sea turtles, so you can imagine how fast some sea turtle species need to swim to avoid being eaten.
Batteries next?
If you put some air out in front of the submarine's hull, it might go even faster due to cavitation effects...
Scientific approach - 0 %
Excitement - 10%
Idiocy - 90%
Glad you liked it!
@@CPSdrone Idiocy is the most popular and favorite genre on TH-cam. How can you miss this? :)
I wonder if this could retrieve the top that flew off my rc boat it’s a 48inch hydro plane from proboat so I can’t find them anymore and it sunk in a second
you could've added the new motors instead of just replacing the old ones since your moving them anyway. use all 4... the smaller ones to get up to speed for a sharper pitch blades on the bigger ones, like a 2 speed transmission.
If you meed too you could add heat cynics to help the water cool the drone off
What happens if you keep the old motors and ADD the new ones? :P
Pod racer?
I wonder how this would do in the mine.
And odd rule.of hydrodynamics is the AFT end of a object in the water is almost more important for Speed then the entry and. If you look at submarine they all have tapered hubs over the afternoon to the propellers, and the most streamline parts of the boats are the Afghans of the control plane
a super sonic submarine is possible, good luck w/ that one.
So the solution for speed was a better propeller and a whole lot of brute force, i kinda feel like the original design could be even faster than this purely because of the smaller profile if you just added this propeller in place of the original and turned the power to eleven. This one definitely turns better tho because of that extra leverage
Correct, they didn’t fix the issue and make a better design, they just added more power…
