Electric RC Hydroplane | Building The Motor Mount 

Ok I'll say it ... You're crazy. But thanks for watchin'!

so do i

Yes but sooner or later you gotta shut off my videos and go build a boat! 😎

Lol. Hunting season now

Good idea! I had thought about that but decided to go with a production mount thinking more guys might want to use it over building their own. Gotta keep the vids relevant y'know!

You live here?!? Let's get you into a boat and RACE!

Awesome!

Thanks for watchin' Robert!

Yeah but I'm a terrible cook....

Videos in the morning, boat work in the afternoon!

Good idea!

Thanks Rick! Have you seen my delrin motor mount video? I built my own, but a company called Stump Fabrication is selling something similar. Should be able to find them on Facebook. Happy building!

Thanks Auz!

Glad you like it! Keep watching for some full-size boat stuff soon!

I like it!

That's awesome! Ok tell Jaxsen not to miss the next video... I'll put a little Jaxon in there just for her!

Thanks Carlos!

Thanks Richard!

Thanks Andy!

Thanks. I think me and Uncle Henry would get along just fine!

I wonder if West Systems will give me a royalty fee? 😆

Attaboy! Thanks Jason

Only 100 times?

Thanks, now I know at least one person did!

Do you still have plans available for the gasser?

The plans have all sold out and I won't be printing more, sorry! From all the plans sold, I know of only two actually being built. The truth of the matter is it's very difficult to do from scratch, and so it just doesn't get done. The last thing I want to do is sell something that isn't useful, and that's why they're no longer available. As an alternative I'd strongly recommend the really excellent kits available from Mike at MLBoatworks. Take a look here mlboatworksrc.com/

Thanks!

Thanks John! So have you built a boat yet? Hmm?

No not yet , I'm new to the hobby but I do run a cat that I bought, i only been in the hobby for a couple of years but I learn a lot watching RU-vid on balance in electrical and placement of things hopefully someday I will have a big enough place to have a little shop to build my own boat right now ,I'm a senior and I live in a tiny little apartment. I hope everybody else that watches your videos appreciate the time and effort you put into them keep up the amazing work I also love Jackson. Thanks once again and thanks for the reply.

Hey I'm not quitting my nitro and gas addictions!

Who, me?

Thanks Riley!

@@M5PerfHydros your very welcome, I would love to build one of these but there is no where to run one or race any where near me and It would end up being a shelf queen, your builds and videos are fantastic

Good one!

Attaboy. Thanks Bobbie!

Good tip!

Thanks for the tip, I'll check it out!

Really? Holy cow that must've been one heckuva hit!

Awesome! Thank you!

Here's a short video of one of mine. Watch the red/grey/white boat in the outside lane of the first heat. I built engines for many of the boats running in the HRL circuit and a few in APBA. Still hold the straightaway world speed record! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-2NngicVKI6g.html

Interesting idea, but a rivet nut leaves a flange on the surface of the material. For our purposes we need a flat surface with no protrusions. But I like your thinking!

Sounds good to me!

I've been there many times! You may know Yan Beaupré, he is a good friend of mine. I've built engines for Rob Stevenson, Leah Hoosick, and Yan... Carbs and cylinder heads for many others. Two Valleyfield wins for my teams! It's been two years since I quit building inboard stuff, but I've been thinking about coming for Valleyfield again next year. We'll have to meet up!

@@M5PerfHydros what a small world, I'm from valleyfield! Let me know if you decide to come down next year! Keep up the amazing work!

Good idea!

Hi Dave, To be honest, I'm really just a nitro and gas guy who knows next to nothing about the electrics. All the parts you see in my conversion video were provided by Bill Brandt at Rattlesnake RC, who took possession of the boat immediately upon completion. Bill is a many-time electric champion who knows his volts, so I relied entirely on his advice. He's extremely approachable and helpful, so I'd recommend you contact him through his website here; www.allrc1.com and don't forget to tell him that I sent you!

@@M5PerfHydros Will do Scott. Im looking at the inexpensive electric systems avalible from China. Price of these is awfully attractive for the 4080 class power systems. It makes a boat like this possible on my budget. The performance you got is pretty impressive. Shows how far brushless motors have come in recent years. I've spent several evenings binge watching your videos. Im learning the boat side of things from watching people who know what they are doing. Im actually an airplane guy with an interest in boats. I fly electric sailplanes and ducted fan jets for the most part. I know composite construction and foam cutting pretty well. Electrical Engineer by trade so the electronics don't phase me too much. Ive pretty much figured that the more watts per inch of hull surface makes it faster. My working theory of rc boat electrics.🤣 Yours is the first electric conversion I've seen in this size range to have good performance. Im mainly interested in your conversion because I live in the home base of the miss madison, and I've got a young nephew who's interested. I can drive downtown to the museum and look at the classic hulls for inspiration. Taking my own pictures makes hull painting and documentation much easier. It's not the most refined hull ever raced but its a huge local pride factor. I just don't want my nephews boat experience to be limited to plastic toys from china.

Good ideas! I'll make a video about materials and building techniques soon

@@M5PerfHydros Thanks!! Looking forward watching and learning.

The best resource for plans is Newton Marine, found here; www.newtonmarine.com/ A much easier alternative is to use one of the excellent laser cut kits available from MLBoatworks here, mlboatworksrc.com/ Go for it... You can do it!

Yup! 6-32 aluminum screws. Get 'em here, cool colors too; www.fastener-express.com/

@@M5PerfHydros Thanks for the info and appreciate your quick response.

My pleasure Wayne

Thanks Paxton. Heck I don't care who wins, I just wanna race! Well, maybe I do care a little bit....

@@M5PerfHydros Ill take racing back before I care about who wins! defiantly makin me sweat thinking about the things you will do with this once racing is back! Going to be a bullet!

Gracias! Typhoon 700 series 840kv

It's a shield for the light bulb. It was there when I bought this drill at an estate sale. Good observation Edward!

Fiberglass resin really isn't a great adhesive, plus it won't stick well to the hull if it's an epoxy fiberglass or wood boat. You'll be better off using a good two part marine epoxy like West System 105/206 or G-Flex. The adhesive filler is West System 406 colloidal silica, intended for the purpose of filling adhesives, also a better choice than chopping fiberglass.

Maybe I don't understand your question... There already IS an engine well in the floor.

@@M5PerfHydros sorry not enough info given. If someone is building a new boat would it be best to keep the motor low as possible and provide a well or not alter the floor and run the motor a little higher to clear the floor.

There's a lot that goes into that decision, but as a general rule I always use an engine well. I prefer to keep the driveline as straight as possible and the weight as low as possible, all within reason and dependent upon the depth of the sponsons

Rattlesnake RC. Bill Brandt is super knowledgeable when it comes to electric boats so I got all the parts from him. Go here www.allrc1.com and if you have questions go to his contact page where you'll find his email and even his personal phone! He's super quick with replies

Good idea!

Yes I use G-flex for the entire build

@@M5PerfHydros Thanks Scott

Cooling is needed most around the windings of the motor, and I really couldn't see cooling the mount as being helpful. Additionally, as best I could tell, the cooling channel milled into the mount is very small and I didn't want it causing a restriction to flow. Am I right or am I an idiot... Who knows?

I are berry intellygant

Yikes!

Between 5° - 7°

Looks good!

@@M5PerfHydros cheers buddy just want to get it out on the water!

And yes I actually watched 100 percent, I’m at work too but I’m addicted to rc boats, and there never fast enough!

I'm a long way from Maine, in Washington State!

Heck I dunno... I'm really just a nitro and gas guy. All the parts were provided by Rattlesnake RC who commissioned the conversion. You can contact them here; www.allrc1.com

Water cooling up on the end of the can has no useful effect, so I don't use it.

@@M5PerfHydros ok thank you, love your videos!

Me neither!
