Electric RC Hovercraft That Will Lift My Weight 

The editing 🤌🏼

You're living my dream as a 14yr old. I was buying leaf blowers on ebay and gluing tarps to plywood. Never got one that could quite slide freely with weight on it.

If you stuck a cowel around that propeller that will increase the efficiency, more pressure and more lift, whilst simultaneously decreasing your risk of getting chopped in half if one of those blades flies off

It's always a good day when Simon uploads 😁

Looks like you have built a very nice leaf collector!

6:35 hands down the coolest moment on RU-vid in 2023

You've probably thought of / tried this already, but to balance the front / back: 1) Close some of the holes in the front to direct/force more air pressure to the rear. 2) Add a scoop to the fwd thrust fan to catch some air and redirect underneath for added rear support while in motion.

Really enjoyable video as usual, thank you. I’ve always wanted to speed build build a full size electric hovercraft too, I can’t wait to see how it turns out. I’ve built a few RC hovercraft, here are some thoughts in case they’re useful: - Ripstop (kite material) is an awesome skirt material. Super tough and light. - rounded corners make less bulges at the skirt base, they are where holes appear. - foam sheets sandwiched between wood are strong, quick and easy. Good for floating purposes. - lift fans are more about pressure than airflow. Two blades leak a lot upward. Wingtips are key, most pressure is lost there. Squared off ends really close to the housing avoids this. I cut a 5 blades ends square. You might get around wingtip leaking by simply mounting the prop just under the plywood and narrowing the opening a few cm. that’d save building the duct too. - a really badly sewed finger skirt is better than a bag, it’s a pain in the arse to make but it doesn’t fill with water on a lake. I’ve been meaning to try out making one like this: Two long strips of Ripstop laid one on top of the other, a taller one for the outside of the skirt and shorter one for the inside, lined up at the base. Sew lines top to bottom to make each segment. Cut apart at the base to make ‘feet’ to conform to the ground/water. Perhaps then sub divide each foot with some stitches to make the pressure on the foot side higher than the inlet side to even pressure inside the bag and keep it inflated when a bit is lifted from the ground. Might be terrible though. - you could add two extra fins on the frame with wire connects for serious turning power. Hi to anyone who read this far! 🎉

Leaving part under the paint bucket unpainted was a nice touch!

Nicely done! Just two points... - It's not gyroscopic precession causing the yaw to the left. It's just plain old torque from the prop. - You'd be way better off taking a couple of inches off the prop tips vs. having them extend beyond the hole. You get most of your thrust from the outer 1/3rd of the prop.

Entertaining as always. Looking forward to part 2!

Great production value. I appreciate the longer runtime of the video, please keep up long form content

Thanks for the great videos & ideas Simon!

Having made several RC & full sized hovercrafts as a kid, a finger-skirt really is the way to go. A bag skirt by itself really lacks the ability to conform to uneven terrain & transition to different surface types.

Awesome! Some ideas: 1. Rather than adding EDF's to the rear, maybe you could angle the rear motor downwards a bit, so it also provides upward force to lift itself and counteract its own weight. 2. The rear motor frame can be made much more rigid by adding some diagonal supports on the frame. Square frames are inherently unstable since they have degrees of freedom, while triangles are inherently fixed because they have no degrees of freedom. #fax #enhineerigh 3. Maybe adding a shroud to the motors would significantly increase their efficiency. And unfortunately also make it a bit safer ;) That way you can also add some mesh on top of it to prevent leaves from getting in. 4. Put the batteries in the front to balance weight.

you should use damp proof membrane it comes in large sheets/rolls and is thicker than what you have

Good work. I've built a few models but not that big! I've used a 12 blade air con fan rather than 2 blade propeller for lift. For the rudder, it's better to use a balanced rudder, that is 25% of the area forward of the pivot and 75% behind. It takes the load off the servo and linkages and provides finer control. For skirts, I used garden pond liner. Easier to repair if damaged. Always fun to experiment though.

Im an Engineer and i cant stress enough how big of a death trap that is. Please, build a cover at least for both propellers.

You drilling through the Led strip... 50 times is the most relatable thing ever.

Very cool! cant wait for part 2

Thanks, will be back for part 2! 👍💪✌

Please cover that propeller! It's too dangerous even at testing stage security is first.

You finally made something that works!! Awesome!

Very good project. I’m looking forward to Part 2. And your English is far better than my Swedish.

1:46 When the fear of being in a spinning prop sandwich scares the metric out of you.

You made a great leaf collector! Congrats

Dude those cuts well placed when doing something time consuming are just so fun XDDD

Absolutely epic bro! Love the build, looking forward to the next upload

Soo iskipped forward and just for lack of context.....at 12:40 seeing the exposed fan spinning at high speed soo flowers to his person is absolutely terrifying lmao...I love it and applaud you sir

What a progression from your first videos to now, man the editing the humour and also your English , you did improve everything ! And I'm not even English, awesome work keep doing what you do!

I really enjoyed the confidence your where showing while building it. And that reflected on the video as well. Thanks for sharing✌️

Your transition effects are always on point

I had my doubts, but i was wrong. That rig is a beast. Looking forward to part 2 !!!

10:55 this is not gyroscopic procession but only the torque of the rotor acting on the frame (same way as an helicopter but with less effect cuz the propeller mainly provides pressure here and not as much mass flow)

dude the editing deserves an oscar!

Man I'm such a fan of your work, amazing as always.

Well done! Next: Calais to Dover on an Electric RC Hovercraft

Bro, when you're at the hardware store looking to buy wood, pick up the piece that you're considering lay one end on the floor hold the other end in your hand close one eye and use your open eye to look down the length of the board. This will make warping obvious and you can use this to select the straightest board possible.

coolest build yet. mesmerizing

Fab as always! Good luck with the big finish!

"So I drilled the foam in. What does that mean? That means I put 50 screws through the LED strip." Bro I fricking died 🤣that is something I would end up doing and felt that one.

Pretty neat project! I'd change the misleading thumbnail though, could upset some people haha

You could angle the propeller 90° so it points forwards and then have some ducting redirect the air downwards

Seeing you grow up before our eyes!

Church free flight test! Nice! 😊

Awesome project. I can see you having so much fun with it.

ove it! I think if you channel the horizontal propeller you will gain efficiency and safety

A rideable leaf blower, awesome!

Can't wait for part 2

I like the buttery biscuit base.

The best RU-vid in existence. Thanks for the content!!!

Woah, I must have missed the video where this massive workshop and all the printers appeared!

this is so much hard work and dedication!! love tou brothr

The project every mechanical nerd kid dreams of... with extra finger loss potential... and failure is always an option (but I have faith in you)

Nice work

I enjoyed watching the liverstreams! More please.

Very cool, but be careful, you might want more shielding on those blades.

Love your channel, builds and mindfulness that allows you to keep your limbs! 😀

That's one nice remote controlled leaf blower :D

I guess by now your neighbors don't even bat an eye or wonder what's hoping on. "Simon is at it again!"

That's so cool, I've just built and rc hovercraft. Would love to build a full sized one

At this point I'm happy you alive and well.

Ahhh, I love everything about you and your videos. I love Sweden and the sound of the language. The men are beautiful as are the women. My straight brother used to call them the Swedish connection. Your videos are so inspiring and fun to watch. Great work mate. Love from Canada

cool project! missed you Simon!

great idea and a lovely video!

It's time for Simon, and you know what to do folks, just relax and inhale 👍👍

I had the strangest realization while watching this video, i literally used to live a few houses away from the school where you were testing the hovercraft. I also used to build crazy stuff in my garage while living there like battlebots and different kind of robots 😄

I think 7:17 sums up how I feel about those exposed props 😅 looking forward to seeing the "safer" in part two

Thanks for your Videos!! Love them!

A hovercraft is the canon event of an engineering canal.

thats a fun project. looking forward for the next part :D

I start watching this wondering how many ESCs you are gonna blow this time. ;-) And happy to see you did another video :) Live your humor!

Nice job waiting for part2

Hope you put more time in planning next time. Good luck

Can’t wait for when he builds a full scale race drone and flies around sitting inside it!

Dual contrarorating EDFs is definitely the way to go

Nice leaf blower!

Looks like a lot of leaves accumulated inside. What if the same happens with water and it rips off on a lake?

“That would be like putting makeup on a pig” bro 😂 an expression added to my vocabulary

great way to pick up the dead leaves :-)

That sure looks SAFE.

You could add a scoop that takes some of the air from the rear fan and directs it under the skirt

Not forgetting the cage for the meat grinder when you fall forward

Your videos are incredible my friend

I’ve been waiting for this video since ever.

beautiful video , can you also make a video about using 18650 cells in a racing quad

“This wood is more crooked than scoliosis” 😂😂😂 nice.

Finally something can can handle the weight of your 360 camera

this is insane super frickin cool!

i think you should print it - we'll see us in three years ;) - i love the way you try thinks and things

Bro you’re insane!!!

Cool !! Thanks for the video !

Would it still work if the front fan were dropped a few inches to the space between the decks? Then you could put some screening over the top hole to make it safer/cleaner

10:33 been there done that have the t-shirt.

Idk what scares me more The open blades The fact that its radio controlled Ir the terrifying low hum of the 2 bladed props

Awesome work.

Dude! We share the same name! I just started restoring some old vintage RC's. Your videos are awesome! Keep it up man!

Fantastic work, dude! Really well done!!! 😃 Looking forward to the next part! Stay safe there with your family! 🖖😊

After seeing the motors my mind went automatically to human sized quadcopter!
