How I built Peter Sripol's 3D Printed RC Utility Ship (3D printed rc boat) - PART 1 - 

You're an inspiration for many of us! Thanks for giving away your plans so generously it's my biggest project so far and I dreamt of it since you built yours and it occupied my mind since.

yooo its actually him!!! I'm surprised its not the pinned comment lmao edit*** it is the pinned comment, but I wrote this before it was

Thanks for your comment. I like your idea of running the motors seperately. I might have to try this, I have a free channel left on my radio I think. What konf of motors and ESc did you use?

@@bernarddostie8892 its a bit of a weird setup re-purposing radio and some motors from other projects. In essence i have two small but low kv motors from a quad (cheapest Chinese specials £5), the cheapest 2 way 10 amp speed controllers (eBay £10) i could find. Each speed controller has its own battery, with the receiver and servo powered by only one side. I use the 2 sticks on the radio linked to the separate channels (forward/back for each motor) and one of the sticks is set up to steer. I favour the motor not running on the same battery as the radio so i still have steering, radio and some power when the main battery runs out (Lipos just die and you can’t hear the warning beeper). I also 3D printed some props with quite small blades to bring the thrust to a more scale level.

Thanks a lot! I can't wait to pull some things around!

Thanks for the advices. I should have tested the glue before using it on the windows and I will definitely buy some canopy glue nexte time (now that I know that this exists! ;-)

Thanks!

I should've thought about a room heater... I'll try it for the next build. Stringing wasn't a issue, but the loss of material broke my heart. The other problem was that the supports broke at one point and I had to intervene with hot glue (half way trough the 48 Hours print (front hull)). The Prusa Slicer doesn't offer the tree pattern support that you're talking about, but I will try to use the honeycomb support pattern on my next big print and if it doesn't work I'll try Cura! ;-) Thanks for your comment!

Thanks!

Thanks! This ship is amazing and building it is even more fun. 😁

Thanks! That was my reaction when I first saw Peters ship! ;-) Now I have my own!

Thank you very much!

Thanks! It was nice chatting with you earlier! Have fun with your projects!

@@bernarddostie8892 Thank you. Yes, there will be a lot of work to do with it !

Thanks David!

Thanks! ;-)

Nice le cousin! C'est tellement plaisant! Tu me partageras un de tes projets à un moment donné.

Thanks a lot, I appreciate your kind words!

Thanks for your kind words! Your project sounds awesome! Be sure to let RU-vid know about your project! ;-)

did you manage it

Thanks for your kind words. It was my first 3D project. I had some help from my brother to get started, but yes, it could be your first project if you buy a reliable printer. Some RC stuff experience wouldn't be bad, but it's not necessary.

@@bernarddostie8892 awesome- I have lots of model making and RC history. I was just not so sure about 3d print. Peter Sripol is amazing, Ive watched him for years and when I saw this beast I was hooked- My next project!

@@t.h.o.r. I felt the same when I saw Peter building this boat and when my brother and I bought a printer it came real. Don't hesitate if you have any questions.

@@t.h.o.r. I've done a lot of printing for work stuff, for 5 years I just upgraded our printers from ender 3 and ender 6e's to ankermaker m5. Its a lot more expensive vs an ender 6e ($800 vs $400) but if you can afford $800 just go for it. A much better printer, and a heck of a lot faster (up to 5 times as fast).

My first 3D printer - Bambu P1S. First print was a Benchy with dozer blade and moving tracks. Second print was the start of a plane fuselage for an Eclipson Model C plane, using Polylite Lightweight PLA. Partway thru the plane prints, I printed the hull for this boat. First print with ASA, this hull, I had a little warpage. I maxed out at 100°C bed temp and started preheating the printer. No issues after that - very nice ASA boat hull sections with minimal supports. Thus with a nice enclosed printer, the printing is the easy part. I look forward to the better 3D printers coming because of Bambu's AMS and overall ease of use. The other manufacturers have to catch up.

Thanks a lot! Printing took more than 200 hours, but I agree that it's worth it. With my new 0.6 mm nozzle and the organic supports prom Prusa I would have saved 1/4 of the time I think. Thanks again for your kind words!

That's a construtive comment. Thanks. Do you think that this ''rudder-elevator'' could remain in a ''Up position'' even when the boat moves slowly? Or should it be adjustable while driving it?

Now I have an enclosure that keeps the temperature higher. I hope it will be better. 😅

PLA slurry works fine. I would recommend testing it before. I used ASA because it's easy to sand and to obtain soft surfaces. It's at least easier than PLA, in my experience. Good luck with your build. It's worth it!!

Thanks for your kind words! I spent a lot of time researching information on how to do things and what material to use. My intention, with this video, was to make it easier for people who would like to build it to achieve it.

Then it's only a question of time! ;-) It was the same for me when Peter's video came out. I waited for a couple of years and now it has become reality! Thanks for your kind words!

@@bernarddostie8892 Exactly :-) Also, I have been "Experimenting" with building boats, mostly from wood. First ever "Real boat" (the ones before were mostly hulls from toy boats in which i slapped some electronics) i build was a Cargo ship designed very loosely around the looks of a real Tanker. That Boat was constantly upgraded over time and rising knowledge and is, what i would call a interesting Design now. I just added lights on it today :-) Quite interesting if you take into consideration that my main interest with RC lays with RC flying. But i always liked to experiment and try new things with RC. For example a sorta like swamp boat from old Plane Floats is in the making Currently. Anyway, i can get lost in writing, and especially talking very fast, so I'll end it here. You have yourself a very nice day :-)

Thanks for your comment and kind words!

I'm sure that there's a way! A lot of patience is surely required!

The composition is acetone and ASA filament. I use support material to create my ASA slurry.

Hi, the bow thruster motor I used is the BR 1811 Racestar 2000kv 2s. I haven't used it in salt water and treated it twice with an anti rust product in 2 years. It runs like on the first day and I played a lot with it. Probably around 30 hours.

Thanks! You should build it, it's a very nice boat having around and building it was pure pleasure. I used ASA because it has the same properties than ABS and is even more resistant to temperatures. I had one bad experience with a PLA printed boat before (it melted in my car when it was 35 Celsius outside). I wanted something resistant this time. I'll look out your channel for your builds if you show some.

Hi, I used this ESC (20A) for the Bow Thruster and I would use the 50A one for the main motors. I Purchased some expensive ESC for the main motors. They are equipped with reverse, but I would rather have installes Bi-directionnal ESC like this one in the link : tinyurl.com/3u73pbfe For the propeller of the Bow Thruster, I downloaded a '' RC boat propeller'' on thingsiverse. I can't remember wich one it was. I upscaled it until the shaft of the spinner of my motor could fit and then I cut the blades so they could fit in the hole of the Bow. I hope this helps. Have fun builduing and don't hesitate to ask other questions.😉

Thank you very much for the reply. I will keep you updated as my progress goes along!@@bernarddostie8892

Take a look in the description of the video. You'll find the different stl files I used

Thansks for your comment and nice words. Just the paint should do the job. I suggest you use some primer before applying your paint to get a smoother surface and to make sure that every little remaining imperfection in the hull is corrected. Happy building!

Wow, thanks for the reply. I am considering adding something to strengthen the keel but will take your advice on mostly just painting. Will keep you updated :)@@bernarddostie8892

Write me an email, I'll send them to you. Dostie.bernard@gmail.com

Thanks a lot!

They was no UNSINKABLE I. ;-) It's a joke! :D

Thanks!

I downloaded the accessories from Thingsiverse and adjusted the size to the model, measuring them piece by piece (I didn't use any scale, just feeling). The accessories that were made by Peter Sripol didn't need any adjustments.

I'm still taking footage for the part 2. It will be simple update with all the options I added and the last modifications I did.

Send me an e-mail and I will send you the different parts you asked for. My email is : dostie.bernard@gmail.com

I would have to search for them on thingsiverse. I'll be able to do so in a couple of days. I didn't succeed to print the top mast Part and had to modify the piece by hand. Three railings came out perfect. I'll let you know when I find them.

I found them on my pc, but not in Thingsiverse. Let me know if you still want them. I could send them to you.

@@bernarddostie8892 yes that’d be great if you could :)

@@Igstormchaser Write to me : dostie.bernard@gmail.com

I searched for ''licence free music for RU-vid'' on Google.

@@bernarddostie8892 sweet because I keep getting copyrighted also how do you add the little section to say what songs are in the video or does it do it for you

@@ThatRCGuy1 It did it for me!

Big thanks

I don't rellay know... It's about 80cm long. I would say its close to 1/35.

I think it's 76 cm. It can take up some nice waves.

Hallo, ich bin nicht 100% sicher deine Frage zu verstehen. Meinst du den Plan den ich um 10:10 im video Zeige? Wenn du die 3D-Druckdateien gerne hättest musst du mir ein E-Mail schreiben : dostie.bernard@gmail.com Ich habe euxh ein Dokument mit allen teilen die ich mir für den Bau besorgt habe.

Hallo, ich meine Elektrik, elektrischen Schaltplan

@@ronaldi40 Ich habe den Schaltplan für dich gezeichnet. Schreibe mir eine E-Mail, damit ich sie dir schicken kann. dostie.bernard@gmail.com

Yes, it's really fragile. I want to build a metal one to replace the plastic one.

@@bernarddostie8892 Nice👍 Btw, How did you position the ballast so it wouldn't get in the way of the electronics and what did you use to hold them down?

I'll show you how I did it in the next video. If you want to see it before, I could send you pictures.

Send me an e-mail and I'll send them to you. I have those files one my Pc, but I can't find them on Thingsiverse anymore. dostie.bernard@gmail.com

Oh! Que oui! Même si la vidéo est en anglais, je voulais spécifier que ça se passait icitte! ;-)

ABS and ASA are almost the same, but ASA seems to have better wheather resistsance and I wanted something resistant (high Temperatures in summer and cold temperatures when winter approaches. I could've used ABS and it would've been the same after all. Thats my feeling.

I wish! 😁 I'm still happy with my Prusa. Maybe the next one will be a Bambu.

It's the i3 MKS

@@bernarddostie8892 I am going to buy a ender 3 and print/make this boat

@@ThatRCGuy1 Go for it!!! I heard good things about the Ender 3, I think it would be perfect for your project. Don't hesitate to ask questions here, it's a lot of work to get everything done and I searched a lot of answers while building. 😉

@@bernarddostie8892 going to get one for my birthday

@@bernarddostie8892 legit just bought an ender 3 s1 pro haha been a while but worth the wait. Finally printing

It has definetely a lot of thrust, but those motors aren't designed to tow anything heavy (they are made to turn fast). I successfully towed someone in a kayak, but I'm afraid that it may fry a motor someday... But I have to try again.

@@bernarddostie8892 It all depends on propellers. The motors can run fast. If the propellers are not high-speed, then the ship will not accelerate. But the propellers thrust will grow. You will get a lot of static thrust, with a zero speed. You can take a dynamometer and "tow the pier" to measurethe thrust. If the motors will not overheat after this measureing, everything is all rigth.

@@GeneralBlackbird I will have to try to change propellers if I want to make this boat tow anything, because those who are installed are a bit overkill. But I have to wait for the snow and ice to melt first! ;-)

The name was an Idea (joke) of a friend!!! 😆 I don't know if another boat named unsinkable exists or existed.

I did noticed that the boat was a bit low in the water and that it wasn't as fast as I predicted (moves a loooot of water), but I still think that it's an awesome design even if the performance isn't perfect the look is nice. This kind of ship ain't designed to be fast either ways. With the adjusted ballast my boat is very stable even in rough waters. I watched your videos and you also talked about 6 lbs of ballast. That's about the weight I put in mine I think. Your FPV set is awesome. I especially like the underwater camera! Good job!

I take this as a compliment, thanks! ☺️ But no, it ain't for sale. So much time spent building it (200 hours and more) that I want to play with it and admire it for many years first. 😁

Bei 10min und 10 Sekunden im Video solltest du ein Diagramm des elektrischen Schaltkreises der Lichter sehen. Es ist unvollständig, da ich einige Dinge nachträglich geändert habe. Ich verwende ESCs, die einen BEC-Ausgang haben. Einer der beiden gibt mir 7,2 V und der andere 5,2 V. Das ESC mit 7,2 V ist mit dem ESC für das Bugstrahlruder, dem Schalter für die Hupe, dem Schalter für den Feuerwehrschlauch und dem Schalter für die Bilgenpumpe verbunden. An die 5,2 V habe ich die Lichter angeschlossen, die immer eingeschaltet sind, sowie den Schalter, mit dem die Such- und Deckslichter aktiviert werden. Ich werde in den nächsten Monaten ein weiteres Video mit mehr Details online stellen.

Wich Asian guy? Peter, the American guy, commented! 😉

@@bernarddostie8892 I'm pretty sure he meant peter, I've seen stuff in peter's video's that gives away the fact that he's Asian (visiting his mom in the Philippines' during the water powered cargoship video)

I understood that he was talking about Peter. I'm not sure that he's born in the Philippines, but it could be. I thought that it was not the best way to talk about Peter by calling him the Asian guy, it's a bit offensive in my opinion, but I can be wrong.

@@bernarddostie8892 I see, Well for me its not really. I am chinese and Idrc when someone refers to me as the asian guy. but... Good point
