I like that Simon keeps everything in his vids and won't just cut a part that doesn't work out in his favor. Great to see the trial and error and the process from beginning to end.
If he cut out the stuff that didn't work out in his favour, this video wouldn't exist.
@@bacon.cheesecake This is true. Lol.
Thats why I also love to watch them. Most of the channels, they don't show failures or they just fabricate a failure to get more "exciteness" on the video. But here i can see this guy tinkering all day long. I also do similar stuff but more with 3D printing and less with RC
Specially the water color part
The trial and error is one of the main sources of humour in his vids tbh
i can watch simon do this kind of things all day
Wow
same :)
I likes this things, too.
Me too
Everyone waiting for a new video, while Simon fucks everything up 24/7 and tries very hard to deliver good content.
Thank you bro!
turns out you gotta move a ridiculous amount of air if your boat displaces a few kg of water😂😂😂
That's how you learn the fastest, fail, repeat, success.
It's your thrust angle. The fan is pushing the nose of the boat and board down whilst also pushing forward so you have massive friction and never getting up on plane. Print a new mount with the nose of the ducted fan a few degrees down pushing its thrust up and back. Pushing the stern down. Thats all it will take to get up on plane and then that power will show.
ye that's what i was about to write
I don't think so: it's the propeller's size. There's a limit to what can you do with a propeller that size, no matter how much power you put in. After a certain point, the propeller starts creating vacuum into which it moves, generating no thrust (i.e. cavitation).
@@guillep2k Cavitate the air? rofl
@@TheJPexperience112 Stall in this case
But yes essentially cavitation
@@StrelitziaLiveries They're not the same phenomena, and it's unlikely that it's either.
Why would a manufacturer create a product that will stall or cavitate (somehow) within it's operating parameters?
you could try and 3D Print Hydrofoils to lift it out the water to reduce the drag.
Just what I wanted to say, I do believe the trust from the props cannot overcome the drag of the body board. Also the trust goes down into the water and I am sure this creates some other type of hydrodynamic drag.
Wanted to say this too!
Wanted to say this too!
this!
That would be my plan. I used to have a pickle fork hydro and as soon as the bottom starts packing air drag actually decreases and the amount of power required for more mph is much less than any other hull. The back of my boat was out of the water past 75 mph
0:59 Already love the editing!
Rule #1 with any performance boat... NO round corners, edges. The water follows a curve rather than break away from a sharp edge. It may not still plane with the weight but you're giving it every chance Simon. Love your work and as mentioned, keep the OOPS moments in!
Awesome work, Simon! Looking forward to the next tries! 😃
Stay safe there with your family! 🖖😊
A tip for the threaded inserts: Push them 90% of the way into the plastic, then push the plastic and threaded insert down onto something flat until the insert is fully inserted. This makes it much easier to have the inserts be flush and aligned with the hole they're going into. It also creates a completely flush mount, and retains the original geometry of the part. They're plenty solid when mounted this way (they pull the plastic out before the interface between the print and the insert fails) and it makes everything look very clean and tidy.
The Jubilee 3D Printer project is where I first heard about this method (they called it the 'plate press technique') and I use it any time I need to press an insert into plastic these days.
After an eternity later he
Is back and he knows that he has a TH-cam channel but I love him.and respect his hard work then any other on TH-cam keep it up love from Pakistan
I like how each step in the process gets this closer and closer to a swamp boat/fan boat.
Always worth the watch, keep having fun with new ideas
It's amazing to watch your videos! Keep up the good work !! :)
11:26 Make an E-cart with that motor
Entertaining video like usual Simon, glad you show how to work through your builds! You figured it out, for an airboat you want a planing design instead of a displacement hull, weight was definitely the issue, less your design. BTW you inspired me, I'm scratch building an electric surfboard :)
Nice
big&flat, like every airboat ever hehe

Great video, informative AND very entertaining. Happy to wait Simon ,gives me a chance to go over previous vids again.
Very enjoyable to watch. It was fascinating using the body board verse the boat.
U r the most consistent youtuber, jokes aside love the content
that crazy russian hacker impression tho! good videos man, keep up the good work!
I could watch these videos all day, even when Simon fails he still makes it entertaining
such an enjoyment to see you work! love this!
This content is so underrated
The momentum transfer at low speeds for an airscrew is really inefficient, your ducted fan isn’t anywhere near as large as it could be. The high speed of the motor needs to be transferred to slow moving air, and you’d want a very large airscrew for that. But the resulting large prop makes the motor spin slower, which lowers its efficiency, so you might even have to consider gearing. In the water you can use a much smaller screw. If you’re not going to use a water propellor, then I’d act to minimise the friction with the water. A hovercraft would be a conventional example, if you’re ambitious you could make a hydroplaning vessel with automated stability control.
One thing many young folks never realize is even if you fail you gain practical knowledge. The cool thing is once you go through enough of these exercises you begin to develop an intellect then you can take on a new project and hit the design pretty close on the first attempt. Unfortunately this process usually takes many years but the more of these excersises you do the more advanced you will be in your later years and that's when you truly get to experience the satisfaction and reap the rewards.
Loved that pond color editing bit!
Make a hydroplane/outrigger! Wanna collab? ;)
Yeeeesss
Yes good idea

Ekranoplan. It kinda feels like the idea is waning off now but ok.
Power on that big boy motor next 😈
Every time you are testing near the propellers I hold my breath 😅
First
Look forward every time you post, great content!!
Love your videos & i strongly appreciate ur hardwork
U should try some back flaps to reduce the pitch when going faster
0:59 proof Tenet is real
Best channel on the interwebs, humor is next level
Just found this channel funny as hell but did open up possibilities for something I’m working on thanks 🙏
You should add a teddy bear or something to make him look like he's surfing/ jetskiing
The way he flinches at 9:15 XD
Most enjoyable! The boat is 'stuck' to the water - no amount of lipo-brushless-mega-watts will change this... Looking forward to the next video!
tack, men blir alltid glad när man kommer in o ser att du släppt en ny video. 10 tummar till dig..
It’s like the old Swedish saying we all know and love; Friskt kopplat, hälften brunnet!
I don't know why, but at first I read: Worked first time, half of it burns.
Turns out "hälften" is the only word I actually understood.
@@maxmustermann2596 😂 The second half you got right at least ^^
You have to minimize the surface touching water to decrease the drag, i recommend you to build a hyrofoil
One of my favorite channels, in the top five I reckon:)
1:00 love the way your soldering iron recycles the smoke like that LOL ;)
Seems like water resistance is the limiting factor: time to make a hydrofoil?
Me: does Simon not have a bathtub for testing floatation and saving time?
Simon: I do, but the on location testing is way cooler.
Me: agreed. Keep it up.
Dying the water blew my mind a bit. Nice vid, you are some of today's finest entertainment
When you started editing the water to make it seem more blue I lost it😂
Make a hydrofoil! You'll get less friction from the water dragging on the hull.
You should make a hydrofoil
Excited for the coming projects, I think a kayak, electric scooter or giant flywheel!
I love your videos bro. an I LOVE your humor!
MAKE A PARAMOTOR OR PROPELLER BACKPACK FOR SKIING OR RIDING SOMETHING
"The rudder is farther down than expected"... Yeah I remember my first time with a girl
I love this idea for these series! Amazing!
I want to see that massive motor in a 1:10 dragster ;)
I am excited to see the bigger motor setup! I like the propeller rather than the turbo fan.
In last videos you were displacing water, but this time just air. Thus, you got low speeds and acceleration. Displacing water creates huge force in comparison to displacing air as water has higher mass and force is mass multiplied by acceleration. Although the acceleration would be little low but the decrease in acceleration will be far less than increase in mass when you switch from displacing air to water.
Yes hydrofoils as proposed below would look like a nice follow up Simon. Always nice to watch your videos 👍
Great video! Looks like you were being held back by hydrodynamic drag, with increased power you also increase that drag so your speed hits a maximum. It's all about getting that body out of the water. If your hull has a lifting effect like a powerboat it might have better results.
Very good your videos RCLifeOn. Got a like.
Nice project!
my input: tape the bottom with some parcel tape. get the trailing and side edges sharp.
If thats not working, run it on a gravel road, its a ton of fun.
Thanks for that masking and color grade tutorial
This is why the Florida airboats have huge powerful motors on top of a light weight hulls. Looking forward to the next project.
i kinda wish that you would upload more. i love the videos. what can i say they have really good content. i do miss the 3d printing ones. but progression is natural. keep making more vids.,.
nice to see u here again :)
Waw,so impressive.I've learn a lot here in
Always enjoyable!
This man needs more subscribers.
8:15 I've been to the Maldives once and when I saw their water color I said that if I saw that at home, I'd start looking for the leaking chemicals plant up river
Your video shows that rather well
Simon.. as usually great ideas... What about to build a boat with foils? It will be fast.. and funnyy! :) I know you can do it! Make this video a present for my birthday! ;)
That water looks so clean and blue
One person MINI Boat! Cmon! That would be awesome for fan :)
Neat experiments to be sure! Thank you!
For the 20kW one that’s for sure enough power to keep you flying on a paraglider/Paramotor. You know what to do 🥳
I enjoyed that a lot, thank you :)
Great video
Love to see more
Excellent, interesting and entertaining. What TH-cam is for. Thanks..
nice to see new content!
Bro pls upload weekly , I'll be here for every video.
Fantastic idea
that google search killed me lol! and the looking at the camera as if you're waiting for some kind of acknowledgement from it
Good experience for sharing 👍👍👍
With the beard (suits you!) and that orange and black hoodie, you're giving off a cool "Ming the Merciless" vibe :)
Its been years since ive seen such a clean build plate on my printers haha
Love the series
Been waiting for the videos now damn 😭👑
Such beautiful blue waters in Sweden, I wish I was there!
That hippopotamus part was so funny!
I think you are dealing with hull speed limits in both cases. Love the new upload !!
"If you aren't using these threaded inserts...." lmao
Looking forward for next video
Loved that you edit the lake water lol 🤣🤣🤣🤣
i love this guys content wish i know about it when it started... shared like sub .... my 2nd fav youtuber ever
I really enjoy waching your videos
hier wird es nie langweilig ... Danke ;-)
Nice one, Dude! Try a bellmouth in front of the ducted fan and a nozzle at the end that has around 90% of the (open) area of the engine.
A V hull works great if you can get up on plane. Maybe use trims or even a hydrofoil on the rudder to help. The flat board had way too much friction.
hope next video takes twice as long as this one did
Hey Simon add a foil wing to it it might lift the whole thing and will give you more speed because of lower friction with water. Would be cool to watch you building a wingfoil 👍
I love resilient people
Hey , im using same 3d model for the boat, added 1 layer of resin to make it water tight , but instead of the propeller ive 3d printed a water jet turbine and the boat startet to glide very good , with a amazing top speed. ive used a old 2200 kv motor from a drone. with 4s and 6s battery.
Ive had a little experience of building air boats on those body boards and I found that the faster you go the more the nylon cover on the board sags at the rear because it fills with water which makes the cover sag at the rear end , you will have to remove the cover if you want to go faster and maybe even waterproof the polystyrene board somehow with light balsa wood and seal it with cellulose dope.
Oh cool! You have a blue Gatorade lake!!!
Great project, If i were building a hull to go fast, i would eliminate some of the drag of the hull with steps (look up stepped hull) that will help to eliminate the hydrodynamic drag of your hull. also if you angle the motor up (propellor facing up slightly) you will modify your angle of attack for the hull. this will give you bow lift, eliminate some drag, and help you up on a plane. this will also help you bow submerge less saving your electronics.
If you want to go off the reservation completely, build some hydrofoils, eliminate hull drag by several orders of magnitude
not sure how i got here but this was so cool to watch
