Making a pickle boat for the kid. Boat is made out of PVC and 55 gallon plastic barrel. I've got a 49cc two stroke engine laying around I want to throw on it. It's one of those motors that come off a pocket bike or stand up gas scooter. Anyhow, any thoughts on how to use it. I'd like to do a direct drive propulsion setup but I don't know what size propeller I would use. I could make a trolling motor out of it but I don't imagine it would work to well without stalling the motor. I'm sure it would rust out as well. So my questions...... 49cc two stroke motor, what size prop do I use for a propulsion (fan) like setup? If I put it under water, what size prop do I use for that? Links would be amazing. Thanks guys!

I'm researching to build a hovercraft, and I am not sure what the difference is between a propulsion fan and lift fan. I can find a hovercraft propulsion fan that requires 19 hp, but an engine like that is too expensive. The hovercraft lift fan only requires 11.9 hp, and I can afford an engine like that. So I was wondering if I could just use the lift fan as a propulsion fan, if I ever decide to build a hovercraft. I understand the difference in the fans' functions, but what is the difference in the fan itself? is it a different size, pitch or shape? ...All I really want to know is if I could replace the 'propulsion fan' with the 'lift fan'

I know that it traps the air underneath until the pressure is enough to lift. But does the lift engine push air into the skirt? and are there holes in the skirt on the inside for the air to be pushed out?

Hovercrafts are great ways to reuse a leaf blower or shopvac for goofing off. Now some folks in Japan are using the same idea to float senior citizens around. These chairs designed at Japan's Kobe Gakuin University can lift up to 330 pounds. The next step is to find someone who can manufacture them so we can get everyone floating along, softly bumping off each other.

Long-time lurker, first-time poster. I very much enjoy this community of happily-twisted imagineers & feel strangely at home when I visit. Been toying with an idea & need some outside-the-box thinkers. One primary issue with recreational hovercraft design is propellor noise. Could a blade-free ("Dyson-ring") fan design be adapted to a hovercraft application? By ducting the required volume & pressure of air into the ring the primary source of noise is...gone. Safety would be vastly improved, eliminating the need (and weight) for protective screening. Fewer mechanical parts also means the craft becomes cheaper/lighter. And if, rather than one large ring, two smaller rings were swivel-mounted they could further simplify the steering (directional thrust) and give the hovercraft another very unique feature. By quickly counter-reversing the two rings 180 degrees, the hovercraft would have BRAKES! I've never seen a recreational hovercraft with the ability to stop quickly (with the obvious exception of crashing into a large, heavy object!). All input is appreciated. Thanks very much!

I have lots of motors; I am just looking for 10-20" fans for my r/c hovercraft. Metal would be preferable, but plastic should be ok (I'll be operating them at around 3,000 rpm). I don't need the expensive high-efficiency low noise blades they sell for hundreds of dollars, just something cheap to lift my 4x2' hovercraft. If anyone knows where I can find some, I would be very appreciative.

Im looking for a 5 hp or more engine, for a large hovercraft project. It doesn't really matter how many rpm's, as long as it runs. no more than 10 hp. hopefully under 150 bucks, it's okay if it's used. if a large fan for any reason is included, that would be absolutely perfect.

Bungee jumping, kite-boarding... Why do all the extremest sports seem to come from New Zealand? The lightweight, canvas-covered wings are attached to the craft with what he calls a "Jesus pin". "If that comes out, you see Jesus," he said. Because the hovercraft is not classed as an aircraft under New Zealand aviation laws, the operator does not require a pilot's licence. Daily Telegraph.

I am designing a hovercraft similar to the instructable " 10hp hovercraft ", but competly from scratch. Finding a blade big enough is becoming a problem. I had the idea of useing the 13 horse motor and pullies to power two 20" fans from a box fan. The fans power is also cut 1/3 from trust to lift. So my question is it powerfull enough to lift 250 pounds.

I am currently working on the design of an impeller driven lifting device utilising the Coanda effect. My 3D printer is of course a great help here but only useful to test the vacuum cleaner assembly that I salvaged for the motor and impeller part. So far it is just I am interesting to see myself instead of reading it on the net but I was wondering if any RC model makers out here would be interested too? I have no clue about the available brushless motors and controllers or how much extra weight for electronics, batteries and so on but could provide the 3D files and design tips if anyone would dare to create a working RC model. Unlike all the designs on Youtube no propeller is used for the lift! Those designs might still use the Coanda effect, or better adjust it's airflow, for the steering but the actual lift comes from a prop. An impeller as used in vacuum cleaner does not provide lift and is more the "real deal". The last real world project that I know of was the Avrocar that was tested during the cold war but never made it into production. Just though it might be an interesting project to build your own "flying saucer" :)

On a hovercraft will I have to create holes in the lift fan, if purchased
I really want to build a hovercraft model. Id design my own but i know id run into center of gravity issues. Id build this one www.model-hovercraft.com/2000tdx/2000tdx.html but it is too large for my likeing and storage. Would it work at 1/2 his measurements. I realize i would need to use a different size motor and prop for the duct. I would probably use the same size motor but half sized prop for propulsion because me gusta( i like) fast.

Well here's the deal. I have 3 working vacuum motors in my basement, waiting to be used for a project. I was all set to build a kick ass hovercraft, but then I realized 2 of the 3 motors are 240v :( I will probably still try to use the one (120v) to make a hovercraft, but I'm really not sure what I could do with the other two. I'm assuming they wouldn't work well as generators...since they seem to spin at such high RPM. I'm pretty new to this stuff but I feel like there must be something cool I can do with the motors. (They are all Ametek motors. The one is a 120v which I successfully wired up and ran off of my outlet. The other two are 240v (50-60 Hz). Thank you for any help/suggestions.

I bought a nice futaba controller set from Hobby Town USA and built a RC Hovercraft with it. It was a failure, so I took it apart. I now would like to tackle something easier, like an RC Car. There is less worry about weight on one of these, like there is on a hovercraft. What would be the best material to use to build the frame? I was thinking PVC, but I'm no expert. Thanks!

I've looked at industrial shop fans 20+ inches in diameter which seem to provide enough airflow to work, but I've never seen them used in my research. Can anyone help?
Asked by Transience 9 years ago | last reply 5 years ago
So I took apart my old vacuum today and took out the motor with the impeller and everything. I put it into a housing and made a little jet car by strapping it to a skate board, which worked pretty well. I got bored the second I figured out it couldn't push me though. XD Now, I'm just wondering what to do with it. I was thinking maybe a hovercraft, but I don't have a second motor to use for propulsion. (plus, I don't think it would be as fun as one without cords to have to drag around.) So my question is... what should I do with it now? As of now, it doesn't really have a use other than looking and sounding awesome.
Asked by tylervitale 7 years ago | last reply 7 years ago
Hey y'all, I was bored, so I made this RC hovercraft, kinda like a Tiny Whoov, from the guts of a $5 RC helicopter (sold at most FiveBelows). The idea is that a hovercraft is more fun than a cruddy helicopter, in addition to being a fun and easy DIY project for the weekend. It could be a nice gift to a kid. My first concern was that the motors would not provide enough power to get the thing moving. They give more than enough power, and this thing can MOVE. My second concern is that the differential thrust steering system (one motor turns faster than the other, steering the hovercraft) would not be effective enough. This is still a problem that I don't have the enthusiasm or time to solve anymore. Maybe someone could figure out how to reprogram the FC board to have more differential thrust (is that possible?), or somehow configure a servo or actuator without raising the cost of materials too much. Anyway, here's the concept, go have fun with it.Supplies:Foam platesHot glue$5 RC helicopter with 2 motors and receiver (LED optional, but really cool)Connector (the battery might be soldered directly to the FC board, so this will make it easier to fiddle with)Soldering iron (not %100 necessary, but it can come in handy)Propellers (see design notes)Design notes:Notice how the underside of the hull is curved and smooth. I used propellers from a Blade Inductrix FPV Pro, but any micro quad propellers should work. Notice the nice little compartment under the FC board where you can stick a battery without the need for Velcro or glue. This would be a very easy FPV mod, but that would add about $20 to the cost.

A while ago, I came across the work of guy in New Zealand who had made a hovercraft that could also fly like a ground effect vehicle. (See it here) And it got me wondering..... What kind of regulations are placed on a vehicle like this? Say I (while in Australia) built a similar craft to his, only smaller, lighter, and a single seater. Well, firstly, I'd like to know if it's legal or not. I'm assuming it would be, but with certain conditions, so; What licensing (if any) would be needed for it/me? And what regulations must it/I follow? Here's what I've taken in so far, although I don't know for sure that it's accurate/true: It's legal, as long as it does not exceed a certain weight, number of occupants, noise level, etc I'm allowed to fly it as long as it is not able to get over a certain height (a couple of metres) It's a wing in ground vehicle, so it falls under the same category as boats, so the same regulations apply. Does that mean I'm not allowed to use it over land....? It'd be helpful if you could just point me in the direction of answers somewhere else, even Thanks

How much thrust does a 9 inch fan give out? Also how about a 1.5 feet R/C helicopter. How much horsepower is required to lift a human. How much thrust. If you had a 100lb man and had 101lb thrust how far up in the air would the 100lb person go. Sorry really dont want to do the calculations right now.

Is there a RC plane or aircraft, (like helicopters or hovercrafts) that can carry a camera and drop a payload. This would be great for pranks or dropping weapons for allies in an airsoft war, maybe even shoot airsoft bb's, that would be awesome. If you know how to make at least the first two or know a product that can do that tell me.

Finally some time to do a short report on the Mini Maker Faire in Kerkrade last weekend: It was realy great. Two days of fun at the Continium. Being a hands-on science museum, it is a great location for a Maker Faire. The Maker Faire was very well organised. I'm sure it was not only because of the bad weather that we had so many visitors. The people showed real interest and were very inquisitive. Mgossye and me build 30 hovercrafts with visting kids and adults. We where actually a bit overwhelmed by the succes. It was great to see other makers and their work and catch up with other Ibles members (emilyvanleemput, janw, IamWe, ynze). I must admit however that for me a high point was a "fan" coming up to me, saying: "Are you masynmachien? I love your blimp projects on Instructables!" :-)

My intention was to enter the Make it Glow contest with a better and more complete version of my forever Light. But after checking some entries I decided against it. There are a lot of totally unrelated entries in the contest and I fail to see the point in entering if obviously noone cares about what goes into a contest. For example a hovercraft, cordless screwdriver, fingerprint scanners, remote controlled robots, space doors or cmputer controlled flower pots..... I though the reason for a contest would be to have stuff in there that fits th contest.... I know some standards are not that high but isn't it a bit too low to allow totally unrelated entries into a contest??? Me, I simply don't see how a contest can be fair if the entry rules are already being completely ignored and obviously noone here cares to remove those entries...
