  • Someone failed common sense class.

  • You need to drill holes or cut slits into the top of the Frisbee for it to get enough air flow..

  • will it blend?

  • Someone failed physics class....

  • i want to make won of thoes

  • You really didn't expect that to take off, right?

  • este tipo no tiene idea de nada xd  por favor leer unos libros de física aerodinámica

  • Make like 40% of the top of the device just open space. Maybe by cutting spiral shaped sections out from the middle to the outer section.

  • Ебанько-это диагноз!!!

  • that wont work there is no air going into it, you fail as an engineer

  • First of get two propellers turning in different directions, get some airflow so it can create some lift. and then put a back on it for steering. What you have there is just a Frisbee with a propeller moving around air under it... If you don't really care for steering, then just get the airholes.

  • this is not a "unknown flying object" its a frisbe<-- wrong spelled i know but any way

  • Nice physics, Newton.

  • have you made one work yet?

  • the air is suppose to pass on top and down. Its some effect , I forgot the name. The disk is too heavy . Try fome foil form disk then coat it with 2 part epoxy in a thin coat. Should be hard as a rock and very lite. :O) happy trails

  • It needs air intakes.

  • I am very happy to see the vidoe after you give this This didn't work not powerful enough. Back to the drawing board

  • I Love The Video It Can Increase My Knowledge The UFOCopter First attempt 

  • Steady I Really Like This Video This didn't work not powerful enough. Back to the drawing board

  • Good, I like that you share this video This didn't work not powerful enough. Back to the drawing board, I wish success always

  • Nice Video This didn't work not powerful enough. Back to the drawing board! That You Share , So Very Nice Thanks You

  • I Really Like The Video From Your This didn't work not powerful enough. Back to the drawing board!

  • khùng vãi luyện

  • Your Video Is Very Useful Sharing This didn't work not powerful enough. Back to the drawing board!

  • It will never fly with that design. The Air has to flow from above to "push" it away from the ground.

  • try to put the battery just above the motor, then make more holes that will make more lighter and also, the air will flow better

  • WHAT ? WHY ?

  • 1- Not enough circulation to gain lift

    2- Low power

    3- Unbalanced

  • kkkkkkkk Epic Master Fail

  • not enough flow of air i guess..

  • you have no airflow. its just moving the air around in there. you need some air intake holes on the top

  • @Raven3one I like to refer to them as "speed holes"

  • Why she Didn't Fly :D??

  • Бред

  • даже не взлетела? херь

  • u need holes on tha top dumb :)

  • nice vacuum cleaner.

  • а что это такое

  • ufo = unidentified flying object, but as you got there a piece of plastic and some electronic parts, so it's not anymore an unidentified flying object, is a piece of plastic, and it also cant be an ufo cause it's not flying :)

  • Make a round hole in the top around the motor it might work

  • it needs three bricks on the top then it will fly for sure XD

  • Only vid ive seen of this maybe use 2 frisbees, make them like this ____

    (____)

    (____) glue them together, and drill evenly spaced holes in the bottom, place your propeller inside, then add a second 9volt, and Houston we may have lift off. Good luck, God Speed, and hope my suggestion helped.

  • ugh ugh ugh MORE POWER!!!

  • yep drill lots of holes and get a tiny brushless and lipo setup and run becaus its probly going to hurt someone!

  • The problem isn't power. The problem is that your fan is taking air in from the same place it is ejecting air to. ie the propeller is simply circulating the same air in a closed system. My suggestion: Drill/cut holes in the top.

  • @05you2 drill BIG holes on the top! just google "Hilly Bike".

  • What air are you trying to blow downwards?! ;)

  • try flipping the propeller so its on the top, use the Coanda effect to generate lift

    probably need a bigger motor too

  • Is this a joke? lol

  • Comment removed

  • put holes on top it will suck air in imagine this is the frisbee: [====0====] only airflow on the sides.... make holes! [=-==0==-=] more airflow from the top and lift off!!

  • lol, even if it goes up a bit (what it won't do without holes in the top) it will spin as hell xD

  • You also need a brushless motor sold in hobby shops. these spin faster and dont burnt out easily.

  • your problem is you need an air intake on the top of your frisbie(?) cut some wholes in the top stretching from the middle to the outside to allow an actual flow of air, and the loss of wieght will mean it requires less lift aswell =D goodluck

  • hovercraft technology...back to 70's...

  • for your next act, try it with a big room fan.

  • make more slots in the top plastic, and balance it with another nine volt on the other side, and when it takes off the top is going to spin the other way so putting blades on it will also help

  • lol  nice phssics bro

  • it cants work in needs air to pass from the top tot he bottom in order to lift

  • lol u re great bro:)

  • Cool concept, but study airflow and propellors to see what you did wrong in this prototype.

  • gay

    

  • thats the new failcopter its the latest fail in technology.

  • I was about to say, there's no air intake. Wasn't that damn obvious when you put it together?

  • let it breath. Cut slots in the top of the frisbee.

  • can you stop masterbating while you are recording =.=

  • shove in a jet engine and watch it burn to death.

  • can you make a ROFLcopter?

  • I'm gonna have to be blunt, but the reason why there isn't any lift is due to it not having any holes on top, for 1) to reduce mass, 2) reduce vacumm pressure to lift off the table and 3) because the atmosphere has weight and without the system exchanging energy to the surroundings directly, it cannot fly. Best of luck next time though. keep trying.

  • hÎ_Ï_fèËl_sô_lóÑElÿ_tÔÐÅY

  • where u get the motor??!!

  • u would be good at making fans :D lol

  • lol tha real first attempt!

  • with that battery on the side youre going to have one hell of a time balancing it.

    If it even took off.

  • keep trying!

  • lol..too heavy...maybe use a styro foam

  • Fail!

  • put the battery and motor's weight acting at one point, preferably the center then make sure the motor spins fast enough to get the thing to lift off.. .. your design shown here will make it topple upon liftoff

  • another funny video

  • yeah thoes blades need to go way faster. I know had an RC plane.

  • You need a way to take air from the top and compress it down but looks cool kids!

  • he does to have an air intake theres a little rectangle cut out

  • its overload..!

  • lol

  • verry heavy,..??

    u can use a small fan

    like from cpu fans its lightwieght but fast to spin

  • I know what you could do put weights o the rim such as metal peices and make sure they're exactly the same distance apart and then drill holes.

  • that?...fly?.....ahahahhahaha!­!!!.its useless!!....ahahaha!.whos idea is this!!??...ahahahahahaha!!!XD lol

  • that?...fly?.....ahahahhahaha!­!!!.its useless!!....ahahaha!.whos idea is this!!??...ahahahahahaha!!!

  • I think we all missing the point here, dude is clearly enjoying finding out and playing with this idea, class job, keep going.

  • @captainzod I agree, it's east to critique something, but YOU are the one watching him do this, so stfu and try yourself. Me? Oh.. no excuse either...

  • @captainzod But he'll learn faster with feedback from those with some knowledge.

  • You might need to make those air-intakes larger rather than slits on opposite sides. You may also need to apply ballast on the opposite side to counter the weight of the 9V battery. I say use another 9V battery and positioned away from the air slots as you have done on the video. What I mean is you current battery position is unnecessarily covering the air-intake which it should not.

  • @narlzp Good idea, but make sure you put that second batter to use, as long as you're adding more weight to the system might as well get some practical use out of it.

  • good failed attempt

  • Even if you had intakes, there's no way that tiny motors going to lift itself, let alone a batery and a frisbee.

  • You people who whine about his design must be blind and stupid. Don't you see the two air slits on the top. (one under the battery and one on the other side) The center of gravity is fine as well. What I would suggest if that you use a lipo battery and a rc brushless motor with a matching speed controller. But you still need some way of counteracting the rotation of the disk once you have sufficient power.

  • jonbobbins. TRUST me. Give up NOW! You have no concept of aerodynamics or physics.

  • it'd work better upside down, with the battery terminals swapped round

  • @tomwtom0 Hmmmm...kind of but not really. The holes in the flying disc would not allow the sucked up (fan-side) air to be forced through quickly enough. The disc would also be too heavy on the battery side. On top of that, IF you could get enough lift through the holes if the disc WAS inverted, balanced out and 'tuned' the best way possible, there would still be the problem of torque. The disc would spin (think action = equal reaction), and the disc would land. This project is doomed!

  • Give the kid a break! he must be 8 years old and thinks he will change areodynamics forever!

  • even if you got it into the air, the battery would make it have an eternal lean to the left.

  • Idiot -.-

  • cut some holes in it stupid!

  • here let me post again that your craft will be off balance and and you an idiot for trying to have some fun. Or i can just read the posts and stop posting the same thing over even though a million people have already posted it 8D

  • even if he made holes it wouldn't work....the inertia created by the spining blade will cause the disk to spin like a wheel .....if he keeps the bat to the side it will spin and and move in all directions uncontolibly......wat the needs is another vfan attached to the very edge like a helicopter to stabilize it ;)

  • its not that its powerful enough, it needs an opening for air to get in. Also you might want to keep the batter as centered as possible, if you dont it wont fly because of the off balance it will create

  • Wow this is very nice! I like the green design and it reminds me of the moller m200x flying saucer. What's cooler than a flying saucer? See what kind of vents you can design / cut, maybe following the circular pattern for the vents to look as cool as the ufo. Keep experimenting. You made a good progress so far! the blades spin nicely!

  • A nice blender!

  • you need some air flo try some holes with flap that are bent to make that so called gyro afect

  • wooow

  • WHY SO MUCH CLICKING???

  • Put a cox peewee motor on it of u can find one

  • Fail

  • About 30 years ago i remember seeing a frisbee with a small glow fuel motor and propellor.

  • you have to be very stupid to think that this crap can hover... people are just stupid!!!

  • This takes the prize for obvious ignorance.

  • Hey guys..there is a such thing as "Constructive" criticism. Maybe if we try to advise him rather than insult him...he may get it right with our help.

  • @pointblizzy telling him that he needs more holes is constructive criticism

  • @1kwood Oh Indeed. I wasn't referring to everyone, just the people who get a kick out of being mean.

  • even if it did fly wouldent it just fly to the left since there is a battery on that side and no counter weight on the other 3 sides? =O

  • ok so many people have said more holes i will say its spinning the wronge way lmao

  • Have the battery and motor below the body, and mounted sturdily in the centre of rotation. Also, make holes in the body such that there is enough space, and the body itself forms a series of blades going in the opposite direction. Otherwise it will lift off the ground momentarily, then the body will catch up with the rotor and will stop generating lift.

  • There is no air for the fan to suck and therefor blow (haha) and create thrust so make holes in the top for the air intake

  • loool of course it wont fly !!!

  • OK,... that's right first you need these holes to let air come in,... and then you also need an other rotor, turning in the opposed direction, and you have to center the weight, and maybe you should use a much bigger rotor^^

  • It would work better if you allowed for air intake on the top, otherwise all it is doing is circulating the air around the propeller which wont provide for any downward thrust

  • You need a mechanical transmission system. That can be as simple as two plastic gears (and it better be, if you want it to be light). A small diameter gear will be attached to the shaft of the motor and a large diameter gear will be rotated by the small and will have the propeller axis attached to it's own.

    This will reduce the propeller's RPM, BUT will increase it's torque...that's what you need not just rpm. a 5:1 ratio might just begin to work (10:1 might be better). Google for "gear sets"

  • Что за тупое видео? что ты эти хотел показать?

  • all u need to do is put holes in the top and add weight to the bottom so it wont roll over in flight

  • Physics fail!

  • that wouldnt ever work, u need air holes on top

  • facepalm

  • awesome!!!

  • CRAP

  • Wow what a waste of time I hope he under stands that this isn't the coada effect the coada effect makes use of pressure differencial n ur just either creating downward thrust of making high pressure underneath the craft therefore possibly creAting downward force research before u try something

  • even without airflow you would think that the air pressure would at list move the frisbee? unless he has the motor going the wrong way lol

  • with a few modifications this could turn into a simple hovercraft =)

  • put the fan on the top.

    see coanda effect ;)

  • fail

  • hmm, i guess its back to the drawing board. The "frisbee" or whatever that is, is probably far too heavy, and you have NO airflow with a contained fan. Look at the rc planes and helis..... very light material with special small motors. Good luck.

  • you need airholes on top of the disc so it allows airflows for proper hovering

  • u need to put small holes (about a centimeter or so) and then you need to try it. the holes let air in so the prop can get more air, therefore more air out and down, which would pick the copter up. good luck!

  • what u need is the tiny motors from an rc hellicopter, the battery from and rc hellicopter, a frispy made of THIN foam and lots of holes for air to get to the blades

  • no air intakes.

  • agreed

  • @tagaEskinita there is but they way to small!!

  • @tagaEskinita There is intakes from what i can see,.. But the position or size doesnt look good for lift.

  • @tagaEskinita R U FUCKING BLIND LOOK AT THE TOP IDOT Thumbs up if u aggre

  • @tagaEskinita hahahha

  • I dont know where his brain was when he made this...

    everyone knows that if you are going to make something that can FLY, it requires air...

    and the curent construction got no air supply, therefore it will never, I say NEVER fly...

  • what purpose serve this video ? add more power and you will see that you device counter turn by inertial

  • gay

  • Unidentiified Flying Object Copter?

    Something tells me that doesnt make sense

  • Euh, isn't it too heavy on one side because of the battery?

  • Nice attempt at a hovercraft....watch out the gov't doesn't come after this technology you discovered....lol

  • As everyone else states, you need holes in the top to suck in the air! This is just a glorified battery flattener that makes a nice whirring sound. Even then, once you have cut the holes, watch it lift up and go upsidedown because the CofG is too high (motor and battery weight above blade). Just don't ermmm...apply to NASA for a job! :o)

  • @digitalbroadcaster or Boeing, or Lockheed, or Cessna, or even Air Hogs for that matter! lol no hard feelings bro!

  • there is no such thing as suction only push when the fan spins the fan does not suck air it pushes the air and creates and area of low pressure underneath the fan so the air above the fan flows from high to low pressure but instead of that flow occuring there is a lift on the craft

  • @016632 I suggest you learn a little before commenting. If you push air on one side of a fan, that fan sucks air on the other side to enable it to push it past the pitch of the rotor blades. Therefore you gain lift. The slot vents cut into this disk are too narrow, therefore overloading the rotor. The energy expelled underneath this fan is simply not enough to allow lift. You HAVE to have suction to allow propulsion. Negative airflow allows positive airflow. Simple physics!

  • bro once again i repeat SUCTION DOES NOT EXIST there is only FLOW of air from HIGH TO LOW areas OF PRESSURE let me give you an example so you can better understand this concept.

    when you breath air into your lungs you dont suck the air, suck is just and expression but it DOES NOT EXIST what happens is you use the muscles in you ribs to expand the volume of your chest cavity thus making the lungs expand redusing the air pressure in your lungs and the outside air flows down trough your mouth

  • passing the parhynx and epiglotis into your lungs, now, when you decrease the volume of your lungs the air prssure increases and the air or gasses in your lungs flow out.

    now what happens with this device is when the fan spins, the air below it is actually made of many molecule in gas form air is not empty and molecules contain mass so does the fan, so when the fan spins the fan hits those moleculs downward it creates an empty space thus creating and area with low pressure the only molecules

  • that can flow into that area are above the fan because they are in an area of higher pressure than the area below the fan and thats why you get the air passing through the fan because you have just created and are of low pressure underneath the fan and an area of high presssure over the fan. now the reason why the craft will not raise when there are no whole is because of the same reason that when the fan spins it creates and area of low pressure but the air is trying to get from the high tolow

  • but it cant because there is no whole on the craft so that same air trying to go from high to low pressure is pushing down on the craft which of course will make it stay on the ground now if you dont understand this concept try google and type down does suction exist and how do helicopters work or you can even go here on youtube

    My basic point:SUCTION DOES NOT EXIST

  • @016632 I know. But I wanted you to type out four consecutive replies on YT, watching that word count going down and down and oooops....next page...

    Repeat x3.

    I was actually kidding you and was thinking of writing something REALLY barmy like 'lightwaves' actually cause the lift. But you are equally intelligent :o)

    I learned that suction does not exist in school sciences many moons ago. ;o)

  • @digitalbroadcaster oh ok i thought you were just being a jerk you got me

  • @016632 I also fly around in helicopters every week so have to know how high and low pressures are applied to the craft. I'm not a pilot, just a film cameraman. 

  • yes holes are needed on the top of the frisbee to suck in the air for lift. like a hovercraft.

  • Put the blades over the saucer. Go read about coanda effect.

  • it may work if you make 4 big cuts at the top of that so you can let the air pass

  • It wont work, simply because he needs a second propeller to negate the action of the first propeller, action-reaction, newton's third law.

  • debrouillard is right, ones at my university have 4 fans each slightly leaning either forwards backwards left or right. to steer you increase the power of 1 fan, but you need more control than a motor and a battery

  • u need to cut holes in the frisbee, otherwise the fan cant push the air downwards
