RC boat build tutorial.
This 50cm or 20" Mono hull is easy to build, even for entry level hobbyists.
But it will be a performer! The first speed goal is 50km/h or 30mph, but we will upgrade it lateron and try to beat 80km/h or 50mph.
In this part 1, we start with cutting the bulkheads. We setup the bulkheads on the build board, and we skin the boat.
The drawing will be available for free, end of June.

Hi Cozy RC!I found yout today!Ialso model airplane and ship models!I don't have any projects for the winter so I found this video just in time!I will finish it in the winter,and it will be swimming in the spring!Hello béla!

[@CozyRC]

Hi Belas, that sounds good! This is a very nice hull to build and run. Enjoy!

[@jamesatkinson7517]

Yes trial and error for the weight versus rise is worth wasting some product and an area for it to expand out of a big opening is important. If you can do it with the deck on it is stronger because the foam sticks to both the hull and deck but even if it’s done to the deck and sanded then the hull and sanded and the 2 pieces have a gap between them when joined it’s still way strong, doing it this way allows the foam to completely go all the way around the deck including the sides. It can be carved once dry as well.

[@CozyRC]

Thanks, good info!

[@OTWRC]

Another Cozy build! Looks very cool 😃👍

[@CozyRC]

Thanks Woods! Great to see some of your boats on the water again, too 😎

[@TimCully]

beautiful.

[@CozyRC]

@@TimCully Thank you, Tim!

[@NoMatterDesign]

Love it. Can't wait for the speed tests.

[@CozyRC]

Thanks, me neither! We will start with a mild setup, for my sons. I'm considering to put a crazy setup in this one lateron, to beat the Recoil 18 performance 😄

[@NoMatterDesign]

​@@CozyRC Speaking of speed tests. I got myself a speed tracker like your. Neet thing (tested it with my RC buggy). On the T-800 front... I just got a freelance contract. It have been 16h days 7 days a week. Damn freelance jobs getting in the way of my boat builds! 😡Well I've been "unemployed for 4 months"... so better not complain too much. 😩 But I have the studio all ready. I send you some photos soon. Cheers

nice laser cut pieces ;-)

Laser cut by jig saw 😅👍

Great job😊 Nice project 👌 ❤

[@sakibian01]

Yaay, build going good! Looking for the speed run already. Sorry, i know it's too soon 😬

[@CozyRC]

Thanks! Yes, looking forward to see this little boat scream across the water!

[@jamesatkinson7517]

If you fill all the left over unused space in it with 2 part polyurethane expanding foam it will be virtually indestructible.

[@CozyRC]

Hi James, Thanks for the tip. I heard some good results, especially regarding hull strength. But I also heard from a Dutch RC boaters, who destroyed his hull with it. He already pit the deck on, so that might be the cause. I will consider it for sure!

[@peteroosterhoff8850]

I personally would be careful with foam. Maybe get some extra info about it. Especially if it is totally water resistant and or doesn't suck up moisture. It is off course strengthening and floatation at same time. If you use it, maybe consider to ducttape (or something else) the hull during the expansion off the foam because its very strong...

[@alschillaci2435]

Some very nice building techniques there. I learned alot. Thank you. I am considering building this design with my son.

[@CozyRC]

I can highly recommend this boat as a father and son project! It's one of my most fun and best running boats to date! My sons enjoy it as well 😎👍

[@brentonbaxter8593]

Awesome 🙌

[@CozyRC]

Thanks Brenton, good luck with your build! We will be in contact ✌️

[@brentonbaxter8593]

What adhesive did you use to attach the bottom and sides to the frame ?

[@CozyRC]

I used wood glue, because it allows you to slide- and tape the pieces in place, before it cures. Then, I sealed it with epoxy resin, to make the hull water tight.

[@AWBuilder]

This is great! I am almost finished making a boat hull with a similar profile to this and look forward to see how you complete the rest of the build since I am a beginner at it making it up as I go and can learn from you.

[@CozyRC]

Thanks! I hope you got some tips from the video. Part 2 will be uploaded next week!

[@AWBuilder]

@@CozyRC Yeah, I built my hull in a similar way to you with ply sheets, but I started with a deck to define the shape and then cut access holes in the deck. I didn't use CAD software. And I was painting the internal wood to waterproof it. Maybe I will add polystyrene into the cavities to add buoyancy in case of accidents? Anyway, look forward to your updates.

[@CozyRC]

@AWBuilder I recommend to add flotation material indeed!

[@Captaraknospider]

Cool little boat DJ. Looks like my little radio flyier.

[@CozyRC]

Thanks! Yes, you are in the same process, so you know all about this, now 😎

[@mustache405]

Wat voor soorten lijm heb je gebruikt voor de boot

[@CozyRC]

Ik gebruik secondelijm voor het lijmen van de ribben en houtlijm voor het plaatwerk. Het best gebruik je waterbestendige houtlijm. Om de boot waterdicht te maken, gebruik ik lamineer epoxy. Daar kan je ook blanke lak voor gebruiken, zoals Ruwa jachtlak uit een blik, of Motip clear varnish uit een spuitbus. Vergeet ook niet de binnenkant te lakken! ✌️

[@mustache405]

[@rubenashikyan6209]

Very nice!! Thanks for your videos👍👍👍 Where can we find the plans for this boat?

[@CozyRC]

Thank you Ruben! I will modify the plans a bit, for an easier build. I will share them in about 2 weeks from now. 👍

[@rubenashikyan6209]

@@CozyRC I have plans for (V hull) it looks like yours but little bit different. I will be happy to have your plans to. I am appreciate to your job.

[@Scoutspartan214]

This is a very fun project that you did, and I appreciate that you are sharing it! I’ve been looking for something to do this summer now that I’m taking a break from school. I myself am an RC enthusiast, and I’m slowly getting into RC boats. Quick question: How did you print the build plans so big on paper? Did you go somewhere to print it on a specific size?

[@CozyRC]

Thanks, good to hear you like it 👍. The plan should be printed on A1 paper size. You can go to a print shop, or print it on multiple smaller paper sizes and glue them together. Some PDF readers have that option. This is a fun boat to build, and not too expensive. It would be a great summer project (just as I build it right now).

[@Scoutspartan214]

This is great! Thank you for the info and keep up with your excellent work. Looking forward to seeing more content.

[@CozyRC]

@@Scoutspartan214 Thanks, more cool projects and speed running will come soon! ✌️

What is the pdf paper size?

@@UsedRoboticShopKhulnaURSkhulna The paper size is A1!

@justinbevier8231 Yes, perfect for making sharp edges!

Where can i get the plans from ?

[@CozyRC]

I will release the plan within 2 weeks. I need to make some small improvements.

[@al1st3m48]

Do you have rc boat plans?

[@CozyRC]

I will work on the plans, and share them in 2 weeks from now ✌️

[@parkourrush3820]

Hey dj, what props do you recommend for the full size wild thing The mini wild thing The hydromite Do i also need to work the propellors before use so yes how? Do you have a tutorial. Could you leave some links not to expensive if possible maybe aliexpress Kind regards mylan

[@CozyRC]

Hi Mylan, please send me an email at [e-mail]. the props also depend on your motor, esc and how many lipo cells your run your boat on. 👍

[@kaprc631]

I want 80 km\h too...😜I am wondering if a high KV low voltage setup is better for this mini boats.

[@CozyRC]

I think it is, for the esc and for the space of the lipo. Like a 4000kV range on 3S sounds good to me 😎

[@kaprc631]

Yes... I was even thinking about a 4800 kv 2s setup

[@CozyRC]

​@@kaprc631I think it works great, but still too low rpm for 80km/h on a small hull with small prop!

[@rajeshsapkal1587]

Hiii Brother, which material you have used for making

[@CozyRC]

Hi Rajesh, I recommend 2-3mm plywood for the bulkheads / frames, and 1mm birch plywood for the plating. ✌️

[@rajeshsapkal1587]

Thank you Brother
