  • lol one little needle and POOF!

  • cool ideas of anigravity

  • kool. it would be more fun on land then water though

  • i think the 1 dislike is his old neighbour lol :P

  • why cant we have this today.. in our streets instead of fucking deadly cars

  • Dear Santa

  • Dear santa...

  • Sick!!!

  • Meanwhile, in Detroit.. I am on YouTube.

  • Ahahahahaha look @ the old guys face when driving it back out of the water

  • thats awesomee!!

    

  • about how much did it all cost?

    

  • OMG that looks so fun i want one now.

  • Ummmm, my question is can it work on water?

  • but does it also mow the grass?

  • Mario Kart any one?

  • Dear Santa,

  • will 10x10 delta fans work?

  • pls replay which should i use for lift a weed eater engine or a 5.5 horse power 3000 rpm lawn mower engine thank you it would mean a lot also what cc or horse power or rpm is the motor u have

  • @rambbo12 From your question I can tell you are not yet an experienced builder. You should do like I did. My first hovercraft was built from plans from Universal Hovercraft. You will use the motors that the plans indicate. If you are using a separate motor for lift, you definitely want to use a 3000 RPM 5.5 HP lawn mower engine, and not a weed eater engine. But don't ever build it from your own ideas for a first job, use plans.

  • How much did you pay all in all?!

  • @MajorLetsPlay I don't really know because I did it in a very long time (10 years 1998-2008, not working very much every year), but I think I must have spent about 3000 euros total. Of course you waste a lot of money when you are making a first prototype because you don't buy the right amount of things. The motor (Raket 120 from radne) is amazing good value, only about 500 euros back in 1998, it costs about 800 I think now. I think you could probably do it for 2000 euro.

  • Good Work!

  • do you have one with a steering wheel and a gas pedal?

  • @imthemovieman Hi, have a look at my other answers on this video and on my channel, I've answered already on that question.

  • I'M THROWING MONEY AT MY SCREEN BUT NOTHINGS HAPPENING

  • but wil it blend ??

  • hey, were are you supposed to get those kind of fan blades, i need to know please thanks

  • @Ricky32908 They are MultiWing brand. Danish brand. The lift fan is type 3H, which is fixed pitch, 560 diameter with 8 blades on an 8 blade hub. The propulsion fan is 800 mm diameter, it uses 3 blades 4Z type on a 9 blade hub (6 of the 9 holes are empty). The 4Z type hub is static adjustable meaning the blade roots are round and you can adjust the blade pitch by twisting the blade. On the 3H blades you have to buy new blades to change pitch.

  • THATS AWESOME BUT......... will it blend?

  • I want one! o:

  • dude can u make a video series on how to make it or get a closer look on it thanks :D

  • dude this is FREAKING AWESOME!!

  • Looksfun, dowant.

  • I wonder how much that would go for on ebay.

  • make a video how you made that!!!!!!!!!!!!!!!!!!

  • i really lyk the design... im plannin to do a similar one for my final year project... here we hav options for 100cc n 125cc 2 stroke engines.... would that suffice? and how much qould the fans and skirt cost??

  • what is the "skirt" on the hull of the hovercraft, made of.

  • @godsrunner1 vinyl coated nylon, 18 ounces per square yard (0.6 kg per m2)

  • u know if u dont move or throttle on water u will sink..

    "Nice design"...sarcasm

  • @TheRcRuler It's made of solid foam 6 inches thick. It floats fine with the engine off, even if you split it in two.

  • @davidleobonner how would you find that out?

  • @TheRcRuler owned bitch

  • @TheRcRuler You seriously think someone would spend that much money without fail safes? Wise ass.

  • @TheRcRuler "Nice comment"... sarcasm

  • “what ya say ?” I said, I take it ear protection is mandatory...

  • What kind of fans are you using?

  • @zacharyf101 Multiwing, from denmark. They are made for industrial ventilation, nylon material with aluminum hub, and reasonably priced.

  • @davidleobonner What do you think they would cost?

  • @zacharyf101 I don't remember what I paid it was a long time ago (10 years ago) but they didn't seem expensive to me for the quality. You would have to ask a dealer, all the dealers are listed on the multi-wing website.

  • @davidleobonner Ok thanks..

  • who the hell disliked this

  • Comment removed

  • plans please (:

  • It seems like it can't keep straight.

  • @venik652 Actually it's very controllable and precise. Problem is I'm a very bad hovercraft driver and I overcompensate for each drift (like a bad car driver on ice). I had it tested by a guy who is an expert hovercraft pilot and with him it did not wander around at all he could get it to go exactly where he wanted. He said it was exceptionally good to control compared to other hovercraft because of the very quick reactions and low inertia.

  • @TheLolnoobs

    hey im making a school project for a hovercraft. but i dont know which motors and rotors are good for it. and where do i have pay attention for?

  • @XxgodpwnerxX Hi, please check out my other answers on this channel or on the videos. I have several answers to the same question as you.

  • looks like somebody stole jesus's car!

    

  • First off, amazing job...

    Im making this for a physics class and i was wondering how you made the skirt....like is the bottom of it open? or did you cut holes in the bottom? thanks!

  • @DallyMadman01 Not open and not full of holes either. It's a bag skirt. Like an inflatable boat tube but attached to the hull, and inflated by the air from the fan. To know more about bag skirts I recommend the Universal Hovercraft web site, hovercraft dotcom. My skirt is exactly like the ones on the universal hovercraft website because that's how I learnt to build hovercraft, by building one of their models first.

  • Now attach a large hang-glider on top of it!

  • You must show me how this is built!

  • is it made out of c skirt? one that just wraps around the sides

  • Soooooooo cool!

  • what type of skirt did you use?

  • @syrianization bag skirt. See the explanation on their website hovercraft dotcom, in "information", "how it operates". There is a sketch of a bag skirt. Mine is exactly like that.

  • so im just wondering before i decide to make one thts big enough to go on water like tht one how much did it cost u to build tht

  • @Shaundabeastsfriend What mine cost will mean nothing since I can't offer you plans to build it. If you get plans from hovercraft dotcom, that is is how I learnt to build hovercraft, by building one from their plans (it worked fine but I don't have it on video). you can build the UH13PT model which goes on water very well, and they give you exactly the cost breakdown for that. If you are on a very tight budget you can build a UH10 I think that can be done for a couple hundred bucks.

  • whut strange mower xD

  • if you built it, could you please, please tell me how to build one?

    the summer's coming and i have nothing better to do.

    please?

  • @soupdexter1 Hi, please see my other answers. there are people asking the same question as you.

  • love it, but its very loud..

  • davidleoBONER lolololololololol

    seriously though, this is epic >:o

  • can i buy?

  • If I payed you would you make one for me?

  • @CharmRat97 no.

  • this is AMAZING!

  • What hapens if you turn it of on water

  • @parkman217 It floats. It's made out of 6 inch thick foam, solid, like a surfboard. you can split it in two and it will still float.

  • you sir are amazing

  • @SNASHING Kind words, thank you!

  • all you need are some blades underneath and it's the perfect machine!

  • ITS AN AIRBOAT! (Half-Life 2 Reference)

  • Ujelly Richfags?

  • @TheLolnoobs bro?

  • @TheLolnoobs what?

  • @davidleobonner It was troll-speak for "I want one"

  • You are a fucking genius

  • @pausastronzo Thanks!!

  • @pausastronzo i was about to comment this but you beat me to it

  • EPIC WIN

  • i love it it's so cool :)!!!!!!!!!!!!!!!

  • wow man that is so epic what shit would u be in though if the gas just ran out

  • @MrGman0909 why? it won't sink. it's made of solid foam. If I run out of gas it's the same as running out of gas with a boat.

  • time to cross the atlantic

  • best hover craft iv ever seen

  • @doggypower1 Thanks! You made my day!

  • Someone has some free time..

  • @davidleobonner how the skirt works? is ist a wall skirt? PLEASE ANSWER

  • @j0sh4D The skirt is a bag skirt, meaning it's a torus shape. The skirt is dynamically inflated by splitting some of the air from the lift and sending it into the skirt. The bag skirt design is completely different from finger skirts. The finger (wall) skirt stays "stiff" when running by mechanical means (cloth tension) while the bag skirt relies on dynamic pressure.

  • @davidleobonner Thank you for your answer, the hull consists of only one plate?

  • @j0sh4D Yes the hull is a solid sandwich of two sheets of 0.4 mm finland plywood, stuck on a 14 cm thick panel of expanded polysytrene with polyurethane glue (the brown stuff for exterior use on wood). You can walk on it with tennis shoes without breaking it, and the bending stiffness is enormous. A panel of one square meter of this sandwich weighs about 3 kilos (2.5 for the foam and 0.5 for the plywood and glue).

  • if it takes 2.5 horsepower to get you to in the air, taking a family of 3 horses will get you free flights across the pacific ocean! problem?

  • Where can I get one and how much will it be, I need one

  • @sperdo911 ebay and £8.000

  • THIS IS FUNNY@#$%^@#^@#

  • @halloforigin There is absolutely no use in having more lift power than what you strictly need. More power will NOT allow you to make a larger hover gap and "show off". More lift just makes for spray on water and makes a mess. If the lift fan installation or the skirt design are bad, then the craft might need a lot of lift power, but that's an aberration.

  • let me guess. these guys are chinese arent they????

  • what is soo cool

  • nice one mate. ius it home made

  • i have seen many homemade hover crafts on youtube and this one if by far the best and fastest and i wish i had one. the only one better is the one made by that really rich guy that flys too i think he had sponsors though this is incredible for a legitimate home made hand built hover craft unbelieveble this things awesome

  • THIS IS SO BADASS

  • I want one !

  • 14 hp, 2.5 hp for lift and the rest for thrust. With a hovercraft you can lift about 50 kilos per hp lift power. You generally want to have 3 times more thrust power than lift power.

  • how much power did the engine have? I'm in the process of building a hovercraft myself but I'm unsure about the amount of power needed to lift myself. could you please reply? it would help me alot

  • @Wallalaahh did you see my answer, I forgot to put the @Wallalaahh on it. I repeat, as I said to the others on this page, you HAVE to get plans from Universal Hovercraft; their plans taught me how to build hovercraft. The question you ask "how much power to lift myself" is answered in their construction book. If you build the lift system right, it should lift 50 kilos of weight per HP of lift. My craft uses about 2.5 HP for lift and it weighs about 125 kilograms in operation with me on it.

  • @davidleobonner i didn't see it unfortunatly, i have finished construction about 2 weeks ago and it kinda failed to float, but it had to do with the skirt design not being optimal, we did had enough power to make it go up a couple of inches but it didn't 'glide' like it was supposed to (too much friction etc.) thanks anyway for the reply, if i ever have a go at it again il be sure to use those plans from universal hovercraft :)

  • ultimate getaway vehicle its lik" oh im so scared chase me on the beach now bye bye bitches im on da water!"

  • make me one?!?!?!?!?!?!?!?!?!?!??!?!?!­?!

  • @brunip please have a look at my other responses (on the channel and on the other videos) to find the ones where I explain about Universal Hovercraft. They are the best plans suppliers. If you want to go on the sea you want a larger craft and they have a nice choice of sizes. As for sea water it's no real problem the first craft I built I ran exclusively on salt water, but don't get any high hopes about waves. Waves are no fun with a hovercraft. Use only on smooth sea.

  • OMG!!! I'm in the Caribbeans surrounded by sea water. Davidleobonner, what's your opinion in using it here and what is the range on a full tank of gas? Need the link to get the plans please. I'm going to start disassembling one of my old karts engines asap so I can send you some pictures and post a new video in youtube. Of course, it will depend on your suggestions if it's going to be on fresh or sea water. Great video, enough to inspire a new dream. Thank you for sharing

  • @brunip about range, it's really more limited by the waves issue (you can't go too far coz it won't handle waves well = dangerous). In terms of fuel consumption it's awesome. Hovercrafts use 3 to 4 times less fuel at equal speed compared to boats.

  • @davidleobonner What store would be the best supplier of parts for a hovercraft like this? I'm interested in making one, but don't have a clue where I could get a ducked fan that large. Propulsion is also an issue.

  • @microwavemaster448 To get all the best addresses, ou really need to get the plans from Universal Hovercraft, get plans for a model such as the UH13PT. Their plans include a big list of suppliers for all kinds of parts. In particular, they sell plans for making your own propellers, or you can buy propellers. I started off by building a UH craft (I don't have any videos of it) that's how I learnt to build hovercraft. In particular the UH plans explain ducted fan construction

  • cool on water till it stalls

  • @Shawnlovessvideos

    It can't sink. it's a block of solid styrofoam six inches thick.

  • @davidleobonner doesn't that mean it breaks easily?

  • @werandomnize No, it has a plywood and fiberglass skin. Sandwich construction.

  • @davidleobonner Alright then. For a minute there I thought you mount all that to just a styrofoam peace. :P Good construct though. +1

  • that is one badass monster

  • Hahaha AWESOMEEEE!!!

  • Million dollar machine!!

  • Hi, for the fan blades they are multiwing it's a danish brand there are distributors in most countries. They are designed for ventilation but work very well on hovercraft. For the design you need to consult the plans from universal hovercraft, in particular the UH13 series models (P, PT) I got my inspiration from those craft and the skirt design is very well documented in those plans.

  • very nice craft

    im building one similar to that of my own, could i ask where you got your fan blades and for maybe a video of the skirt or explanation of its material and construction??

  • Very cool. One observation, the angle of the front fan is directly in line with the head of the passenger. Should any fan blades break loose on the front fan, things would get ugly quickly.

  • @BoogieWithStew no, there's no such risk. The lift fan is very slow turning, only 2500 RPM at full power, with consequently modest tip speeds, in addition each of its 8 blades is feather light and does not have enough energy at full RPM to break through the duct wall if it were to comes off (I did the math). And finally, the stress of the blades at full RPM is a tiny fraction of their max tension stress. So even with a crack through a majority of its section, it still would not fly off.

  • i like the design

  • 2 takter rules

  • @einundneunzig91 yes definitely. In fact if you run the right tuned pipe and the right RPM they are just as efficient as 4 stroke, and much lighter. Most of the bad press about 2 strokes being inefficient comes from running them "off pipe" that is at RPMs that are not right for the tuned exhaust.

  • braver than me!!

  • i think we're at the "new" ATV

  • what if the engine stalled in the water

  • nice hover.

    do you have a plan for this hovercraft??

  • How many moters do you have on that thing and what kind?

  • One motor, it's a radne raket 120 karting/paramotor unit. It's in the back behind the rider. The front and rear fans are both driven by the same engine, a shaft goes from the back to the front, right under the rider.

  • Es exelente es hecho en casa ?

  • Lol, the transition to water brought a huge grin to my face ^.^ I know if I were on that, I'd be thinking right then "Oh shit, oh shit" :P

  • ME TOO

  • Nice! Can I have it? ; )

  • How long and how much did it cost in total to make your hovercraft?

  • what kind of fans did you use for the propulsion and lift? also what kind of engine?

  • The fans are multi-wing it's a danish brand but it's sold worldwide, they are made for industrial ventilation but work very nicely for hovercraft. Very reasonably priced, too. The propulsion is a 9 blade hub with 3 blades mounted type 4Z, the lift is a 8 blade hub with all 8 blades in it. The engine is a Radne Raket 120, its used on paramotors and gokarts.

  • Excellent work!!

  • hey i really need some help making my skirt i know how to make a fingewr skirt but it takes way too long to make. can you show me how you made yours. please respond

  • Mine is made following the method of Universal Hovercraft, check out any of their plans on their web site. But there's something you say that doesn't make sense, it's like you already have designed the craft and want to change the skirt. You can't do that. The hull is either designed for a bag skirt or for a finger skirt, it's because of how the air flows.

  • wait so you have a bag skirt on yours??? i thought it was a wall skirt. please send a pic.

  • I don't have a picture handy but just go on the universal hovercraft web site it's exactly the same skirt as all their machines.

  • Sure beats leaf blowers, lol.

  • I built it by hand and it didn't cost much.

  • Just curious, roughly how much did it cost to make?

     It looks bloody awesome!

  • can't say because I got a lot of parts left & right without counting. The Universal Hovercraft UH13P model which is like mine only bigger, can be built from a kit for $2500 (that's all components including engine). or the UH13PT which is easier to build, for a kit cost of $1800. So that gives you an idea. If you use a secondhand engine and scrounge around for materials you should be able to do for $1000 or less.

  • Thanks for the info, I'll have to look into this

  • did you build this or buy it? can it be made out of wood?

  • I built it. yes, this kind of craft can be made from wood but not just wood alone, you have to stick the wood onto pieces of foam insulation (the stuff you buy in the hardware store for insulating walls).

  • just wonderin what size motor is on it

  • Have a look at my other videos all the information is there

  • you mean brakes? there are no brakes on a hovercraft. To brake, you turn around.

  • I´ve been seeing this videos and still wonder, where are the breaks?

  • very impressive. i always wondered what would happen if the engine stalled on water. would it sink immediately or will it remain afloat?

  • It can't sink. It is made out of solid insulation foam 15 cm thick. You can break it in two pieces and it will still float. But the bag skirt tends to fill up with water if you stop on the water, and then it has to empty out from a small hole in the back of the skirt which is made for that purpose. So, it's better to avoid stopping on water.

  • that is beast

  • nice craft, two stroke? 7hp?

  • HOLY $@&$ i want it!
