Award Winning New Hovercraft Design From Hovery In Brazil

Personal hovercraft manufacturers over the past 10 years or so have tended to copy the construction techniques used in the early days of hovercraft design, that is, rigid hull with a skirt fastened all the way around it with engines of various types blowing air underneath to create pressure and lift. The tendency in manufacturing is to follow the crowd on the basis of what works for one will work for another, but every now and again someone thinks outside the box and innovations arise which can save a lot of money for the consumer. Such an innovation has recently surfaced in a small aero shop in Brazil. Ex-pilot and aero engineer Pilot Alberto Dei Castelli developed a small hovercraft that is easy to operate, packs away into the trunk of a car and is much less expensive than similar models.

If you decide to see a hovercraft kit for sale, or any kind of diy hovercraft plans, please be very careful in what you buy. Remember that safety is paramount, particularly if you're going to be transporting members of you family. Hovery's new design makes a radical departure from normal construction methods and is a refreshing approach to this great new pastime. First of all, the hull design moves away from the idea that a rigid shell is needed, and replaces the normal mono-shell concept with an inflated hull. A large diameter tube is filled with air at low pressure, so that it gives if it hits an obstacle, and is basically used as the container for the pressurized air cushion.

One obvious and glaring issue is the need for rigidity, so an aluminium tubular frame that just slots together like a tent frame is place over, and fastened, to the the top of the inflated hull. The frame provides the stiffness needed, and also holds the operator's seat and control panel, which is very simple - just a joystick! The engine, or engines, depending on the model type, are then added at the rear and it's ready to go. The remaining issues are lift and forward thrust.

The rear engine(s) have two functions in one, and their output has been used in an ingenious way. Most of the air flow is used to drive the hovercraft forward, while flaps built into the inflated hull re-direct a portion of the air flow into the skirt container, which is surrounded by the inflated tube running around the periphery. All that remains is to start the engines using the pull rope, just like a lawn mower, and off you go. the whole thing can be packed up into the trunk of a car within 15 minutes.

Hovercraft Development And History

Over time, the builders of ships and aircraft developed all-terrain-vehicles that ran on the air cushioned principle, so they were truly amphibious. Personal hovercraft further developed in the 1960s and the 1970s, when gas turbines and technology taken from airlines augmented their designs. The 1980s gave way to a fuel crisis, which resulted in a less than optimal cost (and price) for the personal hovercraft. Another issue was the level of technology and materials available for construction. Strong and lightweight materials were simply not used for this type of activity.

By the time the year 2000 rolled around, the patents attached to personal hovercrafts had faded. Now, anyone and everyone who had enough money but not necessarily an incredible lot, wanted to know where to buy a personal hovercraft , or in some cases build their own. Since then, they have been more popular than ever; we are witnessing, in other words, their rebirth. These vehicles are exciting and fun, which is a major factor for youth with the means to pay for such leisure activities, not to mention that safety has become top priority.

Recreational Uses

There are different reasons why one can use such a vehicle for fun or for luxury. The more obvious reason is exploration. With your own hover transport, you can access new locations you wouldn't otherwise have had access to or that you would have had access to, but at a more expensive rate. These locations include the desert, the lakes, the swamps, mud, grasslands, prairies, savannahs, and rivers, whether frozen or otherwise. Thus, you can use a small air cushioned craft to explore these new locations at an affordable cost. You can explore all the nooks and crannies you wouldn't have the time or energy to do by foot.

You can also use them in places which are normally difficult to access because you would have to keep your switching mode of transport. For example, they're ideal for hopping between islands. You don't have to worry about taking a boat, then walking, then taking another boat, then taking a small plane. They are also ideal for exploring the tundra. Exploring the tundra (such as in northern Canada) is normally quite difficult - you have to take a boat or small flight to get there, then resort to traveling with off-road vehicles and dog sleds once you've arrived. But with a small hovercraft, you can just use the vehicle to fly over the terrain. You don't even need to worry about injuring the poor dogs from exhaustion.

Why Buying A Used Car Is Better

It's not really a comparison that can be justified when a person thinks about it, but in some cases it's just better to buy a used car. Of course everyone wants to ride off in a brand new model, but how many people can actually afford it? The fact is, drivers tend to underestimate the value of a used car, especially if they haven't bought the right one.

It's very important to buy a used car in kent from a reputable dealer, because big money is still being spent. Used cars might be a lot cheaper than new cars, but the amount still qualifies as an investment at the end of the day. So what makes a used car purchase better?

It's Affordable

This might be overstating the obvious, but nobody can get past the affordability. Drivers that can't typically afford luxury is now in a position to have it. Some cars never go out of style and given that the car won't cost you half as much as a new one, why not get one? With a used car the chunk out of a budget is significantly less and it will be paid off quicker.

Smaller Drop In Value

Many new car owners don't fully realise how much the value drops the moment they drive off. In fact, the value can drop with a massive 40%. There is no way that this is considered a good investment.

But what about used cars? The story is very different when buying a used model, because the value doesn't drop nearly as much. If the car owner applies regular maintenance and keeps the car in good condition, he or she should be able to sell it for a price close to what was paid. A new car owner doesn't have the same liberty.

The Variety Is Bigger

With used cars there is a lot more variety. Obviously there won't be too many late models, but the door is open for anything else. In the end used car buyers have a wider selection of choice which do make it affordable and the customer happy.

Less Stress

It's understandable that used cars are going to have a few scratches. This isn't always the case, but the fact is somebody else owned it first. Now, for owners of a new car there is going to be a constant nagging. There is going to be a level of fear riding with them every time they pull it out of the garage. This fear is embodied in the smallest scratch or dent. With used models it's not really such a big problem.

The bottom line is to always use a quality dealership when you buy a used car in Kent. Just by looking at the benefits mentioned above it's starting to make more sense. The car will still drive great, but it won't cost you an arm and a leg, so why not make that comparison before making a final choice?

6 Different Types Of Motorcycles - A Simple Guide.

Thinking about buying a new motorcycle? Whatever your reason, if you are interested in buying and learning to ride a motorcycle, you need to know about the different types of motorcycles you can choose from. This is because choosing the right bike can mean a safer, easier, and more fun ride. With that said, here is a brief breakdown describing each of the different motorcycle types.


Cruiser motorcycles are the kind of bikes to show off at your local motorcycle show. These bikes feature high handlebars, V-twin engine designed for low end torque and forward-foot pegs that allows riders to lean back slightly. However, these bikes are not ideal for beginners who would love riding for longer periods of time at higher speeds because pulling back on the handle-bars to battle wind can be very tiring.


Touring motorcycles are designed for long-distance riding and heavy commuting because of their large engines and bigger fuel tanks. They feature amenities like cruise control, enough cargo space, wind protection and heating control. They are relatively powerful and heavy which makes them a good option for experienced riders.


If you are in it for the thrill, a sport motorcycle could be your ideal ride. These types of motorcycles have high-performance engines resting inside a lightweight frame and are optimized for high speeds and acceleration. They feature higher foot pegs and a longer reach to the handlebars, powerful brakes and high-grip tires.


Also known as roadsters or naked bikes, they are the most versatile bikes and are well known for their upright riding position. Their low cost, user-friendly design, moderate engines and flexibility makes them a good choice for the novice rider. They feature foot pegs which are below the rider and handlebars high enough so the rider can maintain a very comfortable position without the need to reach too far forward.


These are motorcycles designed to handle bumps, jumps and other difficult obstacles found on woodland trails or closed racing courses. They have advanced suspension systems, narrower and lighter frames, a kick-starter to reduce weight, increased ground clearance and tires with a knobby tread pattern for increased traction.


Also known as dual-sports, these motorcycles are made for riders who want the best of both worlds as they also offer some off-road capabilities. They are similar to off-road bikes except for the fact that they are legal to ride on public streets. They feature tires that can easily maneuver on both light and narrow frames, dirt and pavement, and even long suspensions. In addition, they offer great versatility for both experienced riders and beginners alike.

Bottom Line

Motorcycles can be incredible, fun and efficient machines. And with the wealth of bikes in this article to sample, finding the best that suit your needs should not be a problem anymore.

Answers To Questions Often Asked About Personal Hovercraft

Any respected small hovercraft manufacturer will have a detailed environmental assessment report that can be freely distributed. Such a report must address the issues of nuisance by noise, safety concerns to spectators, effects on habitat wild life and the possibility of pollution.

Noise is a particular concern as a large propeller is used to provide lift and forward thrust. This is driven by a petrol engine, either two or four stroke, and as such are inherently noisy. It should be noted that a comparison might be made between a personal hovercraft and other pleasure or leisure vehicles being used in the same vicinity. For example, by the sea shore, high powered motor boats are very popular, as are jet skis. Such a study should indicate the decibel ratings compared to these other vehicles.

Pollution is obviously a very strong point, also the effects on natural habitats. On the good side, there are no propellers in the water, so oil doesn't go into the sea. Generally, the engines are contained over the hull compartment and kept dry. For life under the sea or lakes, a noisy propeller thrashing around is more more disruptive to fish life than an air cushioned vehicle which floats over the surface. The question must be asked if any more man made vehicles should be introduced to our delicate environment at all in these times of environmental tipping points?

Safety is a major concern for hover craft manufacturers and design, not only for the pilots and passengers, but also for people looking for a hovercraft for sale. After all, it is quite an exciting spectacle. Modern craft hulls are made from high impact plastic or fiber glass. Glass fiber does tend to split if the hull hits a solid object, such as a rock in it's path. Despite this, many racing hovercraft use this type of construction. The overall construction is light for speed and risks of crashing are all part of the sport.

Such an attitude just won't do for the family man looking for an exciting experience to share with his family. In this situation safety is top priority and not a 'nice to have' feature at all. A slower craft with a thicker hull made from robust material is far preferable to a material that may split and crack under pressure. Expanded polypropylene and similar plastics are revolutionizing the industry and manufacturers of small light personal hovercraft are springing up all over the place.

Steps To Replace Automobile Battery.

Typical indications that a battery is about to fail are headlights dimming, sluggish starting,just recently having needed to jump start your automobile, alternator troubles, electrical troubles.

If you failed to see or there were no giveaways of your automobile battery failing and you end up being stuck at home, it might be worth looking for a mobile automobile battery replacement service close by.

On the other hand you may want to replace the automobile battery by yourself. The following is general advice on how you can do it yourself. Before you attempt to change it, Its advised to examine the automobile makers guidance for your particular automobile.

If you have no experience replacing a automobile battery, or your automobile has exclusive demands like battery registration, you may be better to get an mobile car battery replacement expert to do the job for you.

Before replacing your automobile battery you should understand that most modern automobiles can be very electrical reliant and may store settings for windows, roofs, stereos and other electrical components.

In the event that your automobile battery has already died those settings may already have been lost or if you remove your battery without an external power back up you may lose these settings.

Automobiles installed with Stop/Start systems or that have special charging systems that control the power level from the alternator to battery, require brand new batteries to be registered with the automobile.

These battery registration tools are not cheap, and whilst you may manage to take the automobile to a local service centre that has the tool, they may well not be prepared to register the new battery as they did not install it.

In case your automobile is installed with the new AGM kind battery it should be replaced with the very same kind and not a standard lead acid kind as this will often times result in electronic troubles and premature battery malfunction.

Make certain you confirm you have the appropriate automobile battery for your automobile prior to trying to changing it out, the majority of batteries come with a label probably on the top or side that contains the battery kind, battery amps, and battery cranking on it.

Battery Installation Method

Action 1 All the things switched Off.

Confirm all of the your automotive electrics are switched off and automobile keys are taken out from the ignition.

Action 2 Find the automotive battery.

Depending on your auto kind the following are some of the most typical battery places, underneath the bonnet, seats, and in the boot region.

Action 3 Take away battery clamps.

Your battery may possibly have a clamp across the top or a small clamp at the bottom fixing the battery into place. These are normally held down with 8mm,10 mm, or 13mm bolts or nuts, a lengthened socket and bar set might be require.

Beware as automobiles age the brackets can easily get corroded, which might consist of having to change the battery tray. (Spray some easy release substance on in cases were they look rusty).

Action 4.Connect External Power.

Attach the battery memory saver to the automobile if your automobile configurations have not already been lost due to a failed battery. Always comply with the tool makers information on the best technique to do this.

Action 5. Disconnecting The Old Auto Battery.

Whenever you remove the dead battery, if you have a battery memory saver fastened the battery terminals will certainly still be powered.

When unfastened, you will have to make sure that the terminals do not come into contact with another metal surface. Upon removing endeavour to cover these using a non conductive material.

Most automobile battery terminals use 8mm,10 mm,13 mm nuts these can generally be undone with a spanner.

Disconnecting the terminals.

(Negative Terminal 1st).

The initial terminal to take off will be the negative that has the - (minus) icon on it or the battery area itself.

(Positive Terminal 2nd).

Then take off the positive terminal that has the + (plus) sign on it or the battery itself.

When you have the terminals unhitched transfer them out of the way so you have full easy access to extract the battery (ensure not to allow the removed terminals to touch anything).

Certain auto batteries can additionally have a gas venting out line connected, this should be unfixed before removal.

Action 6. Hooking up the new automobile battery.

Ensure that the battery place is clear and tidy, then make certain the battery terminals are out of the way and position the automobile battery back into its location.

(Attach the Positive Terminal 1st).

Remove the non-conductive cover from the positive battery terminal and hook on to the positive terminal on the battery. Verify it is pushed down and re tighten.

(Secure the Negative Terminal 2nd).

Remove the non-conductive cover from the negative battery terminal and attach to the negative terminal on the battery. Make sure to secure and afterwards re tighten, if you have a battery vapour venting pipe reconnect to the new battery.

Action 7. Detach the external power/battery memory saver.

Any time you are happy that your new auto battery is fastened you may now detach the battery memory saver device. (Do Not Switch on Or Start the automobile with the battery memory saver still hooked up).

Action 8. Start the automobile.

You are able to now start the automobile to check all is functioning as soon as you are happy the new battery is hooked up and the battery saver is detached.

Action 9. Refit the battery brackets.

Once you have started the automobile and are happy all is ok refit the battery brackets making sure you do not make connection with the battery terminals.

Action 10.Stop/Start and Batteries Requiring Registration.

Automobile batteries that involves battery registration you may now link the battery registration equipment and perform the operation.
