Simple homemade hovercraft [nerdboy19]

[Ntheblackhawk26]

How much RPM motor did you use?

[nerdboy19]

@Ntheblackhawk26

I dont know, it depends on how much voltage you put in the motor, the more volt - the more rpm.

[PB10797]

me and my friend are also planing to make one rc hovercraft. But our is made of wood.

ACtually plywood.

[redsoldier123]

i commented before but.. I am new at this.. what is a "servo" and what kind did you use and also what does a servo actually do..? i need to make my hovercraft turn. and i cant figure out a way..i'm going to use a computer fan to make it hover..

[nerdboy19]

@redsoldier123

Sure go ahead :)

A servo is a motor which can be controlled to point in a specific dirrection. So when you pull the sticks on your transmitter in your hands, the servo and therefore the rudder wont just spin around, but will follow your movement.

Just like in a car, just because you move a little on the steeringwheel, it wont make the wheels go around and around and around.

[Raketemax1]

you don´t have an airbag : (

[nerdboy19]

@Raketemax1

Nope, airbags are for cars ;)

Irony off:

Nope, it hasn't, but go watch my newer video - it is a fully funktional hovercraft :)

[Hello3427956704]

needs an aircussion.

[cambigfoot88]

you mean airboat



[nerdboy19]

@cambigfoot88

No.. its a hovercraft :P

An airboat does not get any lift from neither the main rotor or an external lift-generating engine. A hovercraft Does get this lift, by making a cussion of air underneath the craft - like my hovercraft.

Hey Where Did You get These RC?

[nerdboy19]

Hi there.

I got the parts from my local RC hobby shop, you can also get them online :)

[jssk1234]

@nerdboy19 can you do a tut plzz i have some prob with the stering =( and more soo plz can you do a tut

[nerdboy19]

well, since its a long time ago i builded this, it is now disassembled. But if you mail me with your problems, ill be pleased to help you with them :)

[jssk1234]

@nerdboy19 but i just vant a tut =) plzz

[nerdboy19]

Haha ^^

Well, if i'm going to build a new one ill deffently making a tutorial for it ;)

But for this one, i just cut some flamingo pieces, glued them together with hotglue and threw a motor and a servo on it :)

If you can figure out how to make the electronics work as you want it to, you have made 97% of the hovercraft :)

[jssk1234]

@nerdboy19 but pleace!! i try and try but it dont work pleace do a tut just a tut

[nerdboy19]

Well.. but, lol yeah.

Im sorry but i cant make a tut right now. Im bussy with gymnaisum right now so the time wont really allow me :( But if the electronics is your major problem, then you just find a nice already made tutorial here on youtube or on instructables . com :)

You take your motor and plug it into the ECS (electronic speed controller) and plug it into the receiver,and same with servo and finaly you plug your battery to the ESC and well you have to turn on your radio :)

[nerdboy19]

As for your 5 other comments saying "pleazz pleazz pleaaazzzzzz" i have deleted those, since i compare them to *spam* and i wont tolerate spam on my videos. One or maybe two "please" is ok :)

[jssk1234]

@nerdboy19 but can you find a nice tut for me about how to make a rc hovercraft ?? =)

[nerdboy19]

-again, please just *one* comment telling what you wanna say.

Well, i can try sure :)

[ytvman16]

man you could use that one as an air boat! just cut the front on an angle and it should skim across the water just like an air boat!

Reply plz

[nerdboy19]

Yeah i could do that, and i have done it ;)

If you go watch my newer video, i've made a hovercraft with a plastic skirt underneath it, and it can travel across water.

[rcrallynight]

try on water:D

[nerdboy19]

Not with this one though, since it wouldn't work properly cuz of the "simple skirt- design" but my new hovercraft, with a skirt, made it on the water, no problems at all :D

Unfortunatly these videos are from long ago, and since then, my hovercraft has turned into other nerdy inventions, so no videos of it :)

[neutroninvention]

what do u use for the skirt???please help me

[nerdboy19]

This hovercraft was just a quick simple build to try out in an afternoon, so actually it doesnt really have a skirt. Not one in plastic, but just an "out line" under the hovercraft, to make a small empty space for the air pressure to build up in :)

Hope that makes sence

[IllegalMavamaarten]

Very nice :D

[SebitaLugano]

Excellent!!

[nerdboy19]

Thanks again! :)

[Watalum]

could you tell me how you made it. I want to make it. So make anther video explaning it. Please it was very cool!!!!!!!!!!!

[nerdboy19]

Hi there :)

Thanks for the comment :)

I have already made a video with some closeup photos of the hovercrafts :)

All you have to do, is take a peice of foam, glue an outerline under it, a "skirt", so the hovercraft stands on a edge of foam.. makes sence? ... well, and then you have a motor on top, blowing partly air into the skirt, and partly as propolusion :)

Good luck :)

[littlemexicantheif]

could you pm me the link for how to sjhape the rudder and with what

[nerdboy19]

Well, no much work in it, just take a scrap piece of depron foam like material, and slice it with a razer blade :)

[littlemexicantheif]

to me its a simple built go to radio shack buy a builter it your self rc kit you might want the plane or helei becqause it more powerfull as for me i just buy rc stuff from my local thrift store and buy a rmote at radio shack

[nerdboy19]

Exactly, get started with a DIY kit, untill you know which RC-parts do what :)

[ytvman16]

its a air boat! duaaaa

[nerdboy19]

Lol, yeah :)

[rbmdl]

i want to make one too

[nerdboy19]

Well, get going :D

Its fairly easy actually, just get some scrap foam, and the electronics :)

Good luck

[halodude510]

just buy a micro rc airhog thing mouch cheeper only 30 but small

[nerdboy19]

Well yes, but you wouldnt have the same way of control, i mean, it would not be as fun as this.. btw i have made a skirt version wich is WAY more better than this one, but yeah, you could do that if you cant afford the rc equipment.. :)

[theqman13]

you should put wings on it and make a hoverwing

[nerdboy19]

Im going to do that some time, it would be awesome, then i just need to put a bigger motor on it, since it wouldnt be able to lift itself with my curent motor..

But deffenetly, it would be awesome :)

[DualDesertEagle]

Mine is nearly the same, but a bit faster.

[nerdboy19]

Hi there

Nice hovercraft :)

No wonder its faster than mine, LOOK AT THAT MOTOR AND PROP! :O :D

LOL, But yeah, put a skrit on it, you wont regret it! :)

[Arnout1990]

Soo you have actually skipped the whole principle of a hovercraft (no skirt), and just made a piece of foam with a big motor and propellor on it?

[nerdboy19]

Yeah almost, because i have kinda faked a skirt, by gluing a thing outerline of foam under the hovercraft, so it does act like a hovercraft, it isnt just the motor lifting the whole thing, dont know if that makes sence, lol,

Thanks for the comment btw ^^

nerdboy19

[FoamandTape]

yup, those are the best (easiest) way to make a hover craft :D

oh, try moving the CG rearwards it might make it more floaty, since the duct is closer to the back.

[nerdboy19]

Well, after i have put a skirt on it, im never building one without again! :D

But yeah, to start off with, this is Way more simpler than making a skrit, even though, that wouldnt be too difficult, but yes, to start off with, this is really awesome to understand the principle of hovercrafts :)

[TBODproduction]

make a video showing us how to make it or what we need to make it

[nerdboy19]

I have been kinda bussy at the last months, so i havnt really made any new vids, and therefor not posted any more specific info on what i have used to make my hovercrafts.. But if you read through the comments to this and my new hovercraft you will get all the info you need, i will make a list of things you need and everything and post it on my blog when i get it made, and do a little fancy annotation here on the video and on my other one..

Geeky greets nerdboy19

[dsavetark]

ok i can try but its kinda rough in flight>>>

[dsavetark]

i did one today at my physics lab it lifted 1 inch of the ground with only the thruster motor...

[nerdboy19]

Cool, please upload a video if you have the oppertunity to do so :) i would be glad to see that ^^

[dsavetark]

ok thanks for the info did you buy it

[nerdboy19]

no problem, and nope, everything is homemade - not the electronics ofcourse, but i made this hovercraft all by myself :-)

[dsavetark]

wow its flying ,ine is to heavy because of the back rudder motor and gears...

[nerdboy19]

well, my servoes are "micro servos" so that deffenetly does something to the weight, but try with a more powerfull motor, that would be cool :D

[stanedblock]

how did you make it mocontrol, and what type of fan did you use?

[nerdboy19]

How i made it controlable? im using R/C equipment, (transmitter, receiver, batteries...) the motor i use is an ordinay Graupner Speed 400. they are fan'tastic to things like theese :)

[MaggieMovies]

I have a suggestion, I think you should hollow out the Styrofoam to make it lighter. The fan is fine but you can also use a smaller fan on the bottom so it doesn't drag as much.

[nerdboy19]

Hi, this was only a test settup to see how the controls was and i just wanted to make somethink "nerdy" i have made another hovercradt if you see some of my other videos, + i have made a really big one (which isnt on youtube yet, will upload it asap) which easily go on grass and everything, just by making the body bigger, but with same setup :)

Enyway, thanks for the advice. i may try it out, if i build a small hovercraft for my cousin :D

[marcospabloyruben]

great I am spanish

[nerdboy19]

Thanks :)

[sipperlapskovs]

Den er sgu da fed. Men jeg kan nu bedre lide din update.

Undskyld jeg ikke har set på den før nu, men jeg har ikke været så aktiv på min account før nu.

[inventor700]

well.. i like it.. i would like some close ups if you will send..

[nerdboy19]

Check my new video, a little slideshow with closeups of both this hovercraft and my new skirt-edition :)

[cantelli11]

the motor you used looks like a hair dryer motor, isn´t? I have one and I´ve connected it with a transformer of output:9.6v-200mA and it turned very quickly, I`ve also tryed with a 4.5v motor, it rotated faster than, but it makes the transformer get hot and it spends too much energy,I don`t know why :/

but I`ll use so many bateries and a hair dryer motor, and now my hovercraft will go fast

[cantelli11]

yes, it could be nice for me if you send some closeups

[cantelli11]

how does it go so fast?Have you used just one baterie 9v?

[nerdboy19]

I've used a 2S (2 cells) 7.4v LiPo batteri

And the motor is a Graupner Speed 400, maby a bit overkill, but it works fine :)

Check out my new edition (with a skirt) it is extremly fast, and very hard to controll, well i didn't have much space to play with it in the video, but you get some kind of idear of how fast it is.

I could send you some closeups if you are interested???
