Flybarless Rotor Heads – The Ins And Outs

What was the flybar for anyway? The flybar performs three basic functions stabilization, amplificationof cyclic input, and resistance to pitch up in forward flight.

Stabilization: While hovering a wind gust may try and move (tilt) the main rotor. The flybar will be differently (less) affected, and the linkage system will adjust the pitch on the blades to resist the change.
Amplification of cyclic input: When the swashplate tilts and moves the flybar, aerodynamic forcesimposed by the flybar paddles change the spinning plane of the flybar, and again through a series oflinkages this then changes the pitch on the main rotor blades. This means the servos work less hard toachieve a cyclic input.
Resistance to pitch up in forward flight: In fast forward flight the blade advancing into the airflowcreates more lift than the blade retreating in the airflow. This causes a pitch up motion of the helicopter.The flybar again tries keeping in its own plane of rotation, and through the linkage system adjusts thepitch on the main blades to resist this change.

So the electronic components of the system take over these tasks from the flybarSo why ditch the flybar and change to a flybarless head setup?Flybarless helicopters have arguably better all round aerobatic performance. But they are also great forscale models, aerial photography platforms, etc
Advantages include:

Less rotating mass
Lower drag
Combination of longer flight time and better 3D performance
Less mechanical complexity
Infinitely tunable flight characteristics, including improved stability if desired
Looks cool!

What is required:

The Flybarless Head Itself It is ideal to purchase a custom designed flybarless head for your size of helicopter rather than try and modify an existing setup. There are several reasons for this:

The geometry of the head is important
You are purchasing a product that is known to work

Flybarless Electronics You require a system to take over the role of the flybar. There are two and three axis units on the market. For general flying a two axis unit (meaning you still require your own tail gyro) works very well. For 3D flying there are advantages of three axis units, however the two axis ones still hold their own.A two axis unit essentially contains two heading hold gyros (left/right and fore/aft cyclic). A three axis unit adds a tail rotor gyro also. Much like the way a traditional tail rotor heading hold gyro works, the cyclic gyros have the ability to stabilize the rotor head from wind gusts, etc.It is possible to fly a flybarless helicopter without electronic stabilization. However, the task is much easier with the help of an electronics package. You would not fly your helicopter without a tail gyro, would you?
Servo Selection Fast digital servos are preferable. But again, depending on your flying style,any reasonable servo will allow you to experience the flybarless feel.

In Flight: Flybarless helis can be set up to behave in an almost unlimited number of ways. With a flybar,it was time consuming (and expensive) to try a variety of flybar lengths, different paddles, and flybarweights. With the electronic flybar it is simply a matter of changing some of the programmableparameters in the unit itself and you have a whole new feel to the helicopter.There are some further flight differences with a flybarless heli. The cyclic controls now command acyclic rate from the rotor head. So if the helicopter is on the ground and even a small cyclic command isheld, the cyclic servos may move hard over to try and achieve the commanded cyclic rate. So it isimportant not to add cyclic control until the helicopter has lifted off.Autorotation performance is overall improved, but somewhat of a different technique is required torealize this increase in performance.

Ear Hook Headphones Are Comfortable And Lightweight

You must have felt uncomfortable with headphones while sleeping. You can now enjoy sound sleep with slim ear hook headphones designed specifically to help you enjoy a great nights sleep. There are ear hook headphones available with 1/4inches and you can hardly feel foam covered speakers attached to your ears while sleeping. Rubber-coated moldable memory wire of ear hook headphones offer custom fit. The headphones are compatible with all devices and accepts standard headphone plug. The earphone comes with sturdy sided travel case and satin eye mask.

When you get ear hook headphones with rubber-coated memory wire, you need to adjust that to fit in the contour of your ears for the first time. The bend in rubber-coated wire must be free from sharp turns or kinks. The foam side speaker must be positioned firmly against ear of yours, over ear canal. This position will help you enjoy best quality sound and you will have no discomfort sleeping while wearing it. The memory wire can be bent into any shape and you can go on adjusting it, until you get the maximum comfort.

The memory wire should be first bent in the shape of a question mark and a smooth bent should be maintained. Thereafter, the memory should be hooked over and around ear back. The speaker should be above ear canal with the logo facing out.

Ear hook headphones with advanced features are compatible with Droids, iPods, iPhones, MP3 players, other kinds of mobile phones with standard jack of 3.5mm. Even though the earphones are compatible with headphones, these offer best performance with bed phones. The Smart Mode puts off music automatically when you are sleeping. There is the Timer Mode option that reduces music volume as timer continues to run down. This feature is available in Android only. The Basic Mode in ear hook headphones turns the whole screen into pause/play button, so that you can easily operate it in dark.

Ear hook headphones can be worn while travelling in cars, train, and plane. They are comfortable, light, and highly suitable while traveling. Adjustable moldable memory wire has made it easier to be worn during workout sessions as well. The wire can be adjusted to fit in your ear tightly while performing exercises. However, remember that if you are sweating excessively, the foam ear pad may experience premature wear and you may have to replace it.

Mechanical engineers worked round the clock to conceive ear hook headphones designed specifically for those who are passionate about music and feel comfortable wearing them to bed. There were computer-aided designs used to come up with this marvelous creation. There were many prototypes made with varied adjustable features, thickness, and quality to attain perfection.

So, if you are planning to buy ear hook headphones, browse online for different available options and look into the price range. You can look into testimonials and reviews posted online to know about feedbacks offered by customers, who have already used the product.

Unique Birthday Gift Ideas Your Man Will Truly Love

If you want to give your man something more unique and memorable on his special day, consider the following gift ideas: delight him with game or concert tickets; surprise him with a barbecue party; give him a gift card from his favorite shop; ask his friends what gift your man might want to have; get sentimental and gather greetings from family and friends; and consider giving him a gadget.
Each year, you must find a birthday, anniversary, and Christmas present for your boyfriend or husband. Same old gifts like ties, pens, and shirts are what you are probably tired of giving. The next time you want to give your special man a gift, you can use some of these more unique gift ideas to help you find the perfect present.
Surprise your boyfriend or husband with tickets to a sporting event or music concert
Go with the more unique birthday gifts and get away from the ordinary. Instead of buying a traditional present, surprise your boyfriend or husband with tickets to a sporting event of his choice. Actually, make it a pair in order to share in the fun with him. If you are not really up for it, you can at anytime ask his best buddy to go with him instead. You may also consider giving him show or concert tickets, depending on his interests.
Surprise your man with barbecue party
Guys love cookout parties in backyards complete with refreshments and good buddies around, so why not throw him a surprise party? Inform your man’s closest friends that this is going to be a surprise party. Get food, drinks, and some fun games ready so that you can play during the party. To complete the amazement, find some old videos of your man from past birthdays and other special occasions and do play them during the party. He is certain to remember this birthday for as long as he lives.
A gift card from his favorite shop is what you should give him
Are you not yet decided on the item to be given? The shop he frequents most would be the ideal place to get him a gift card, don’t you think so? Maybe, a particular hobby shop, sports shop, or electronic store is where he loves to shop a lot. Aside from being saved from confusion, your man will get to choose what he really wants to have. Alternately, you may also consider giving him a gift voucher from a larger retail store to give him more choices on what he can buy for his birthday.
Ask his friends what gift your man might want to have
Asking your man’s close friends will help you choose the right gift for him. Men discuss “guy stuff,” which they are reluctant to share with women. Ask close friends of your hubby about his latest hobby or ask them to help getting an idea of what he could be interested in. This way, you will truly surprise your man on his very special day.
Get sentimental and gather greetings from family and friends
Collecting greetings from his family, friends, and relatives, is a truly unique and special gift for your husband. This could be achieved by taping an audio or movie salutation for a CD compilation. You could also ask participants a long time before to write down their greetings. Paste the greetings in a scrapbook along with other memorable pictures, favorite quotes, and other interesting stuff you want to include.
Present the man in your life with a new gadget
Is your guy a technically oriented? Consider giving him the latest gadget around or any gadget he is interested in. That, of course, depends on your budget. New gadgets such as phones or game consoles will do the trick. You are aware of what his favorite things are.
Men are not really hard to please, but they can also be very indifferent about your gift. What you need to do is just stay away from the common gifts and think of the more unique, interesting, and memorable presents.

An Update On Clear-cut Nikon Camera Methods

If you see the user controls of these digital slr cameras, you will find two command dials. It is simply your best choice to boost the power of your Nikon D90 video recorder. There is red eye reduction feature to eliminate red eye in pictures. There is also a built-in Speedlight flash that has a TTL flash control. 8D AF Nikon LENSES have no internal AF motor and relies on a slotted drive screw operated by the camera.

Proclaiming your favourite digital camera model is like deciding upon your popular football staff, or automobile. The camera may be used for continuous capture of image after image in seconds with the use of its 12. To check out the list of nikon coolpix visit to the android phones and gather all the updates of new technology. Although good quality and final results are two components that generate those who are experts and non experts alike to shell out the dollars for the Nikon D3100. Improve you photography skills with the striking Nikon Digital Cameras.

If you go to the store “boxes” for the best price, do not expect service. This allows you to adjust, focus and shoot through touch screen interface. At first glance, this device looks like a DSLR, but if you look closer, it’s far lighter, compact and portable than DSLRs. Ironically, Americans were quick to start buying cameras and lenses from their former enemies. Similar to the V1 in most ways, the J1 will not offer an optical viewfinder and will offer a built-in flash.

It may not be the best professional digital SLR that money can buy, but it has a quality that is hard to match. The first is classic view of a docked space shuttle with cargo bay doors wide open and it appears as though a large cylindrical object is being unloaded. But in case of no backup one need to use tool to recover lost photos. The D90 is compliant with SD or SDHC memory card, it can shoot at 4. s technical specification some of the most common DSLR cameras that are compatible with this particular flash model.

But if you have prior knowledge in the field, you can easily choose what satisfies your demands and necessities. Nikon released a series of digital photos from NASA taken in the International Space Station orbiting the Earth. Remember Google only gets paid when someone clicks on your ad. At the beginning of this Nikon 1 review, I said that the new compact system interchangeable-lens camera will change the world of digital imaging, and I stand by that claim. Then download Nikon Coolpix S9100 photo recovery program, Card Data Recovery is a good choice.

Electronic Control Module Tuning With The Unichip Q

The up to date Sequential Electronic Fuel Injection Control System is made of sensors which observe the actual engine requirements, the Powertrain Control Module (PCM) which operates the particular system primarily based on return signals from these electrical feedback sensors, as well as actuators which are powered under the control of the actual ECM.

The ECU (Engine Computer) carries out activities such as fuel injection control, idle air control, and spark ignition control.

In addition, the Powertrain Control Module is loaded with many different diagnostic test settings which usually streamline trouble shooting any time a new trouble code appears.

The two most common calibraion tables that you need to manipulate or modify is undoubtedly the timing map and as well fuel map

Ignition timing control

The ignition power transistor placed located in the ignition main circuit turns ON and OFF in order to regulate the main current rate to the ignition coil. This controls the ignition timing so that it will generate the optimal ignition timing with regard to the engine performing conditions. The actual ignition timing is determined by the ECM (aka The Blackbox) as a result of rotational speed, air flow, engine coolant temperature (ECT), and atmospheric pressure.

Injector control

The injector open milliseconds (MS) as well as injection timing remain controlled so that the perfect air to fuel mixture is delivered to the engine to correspond to the continually-changing engine operating conditions. A correctly scaled injector is mounted in the intake port of each cylinder. Petrol is sent while under pressure (around 55 psi) coming from the gasoline tank to the actual fuel injectors through the fuel pump motor, with the actual pressure being regulated by the fuel pressure regulater at around 55 psi. The controlled fuel is then distributed evenly to each one of the injectors. Sequential fuel injection is usually performed one time for every cylinder per two rotations of the crankshaft. On a four cylindr engine the firing order will be 1-3-4-2. Each cylinder has a dedicated gasoline injector. This is known as multiport injection. The ECM (Engine Computer) provides a richer air/fuel mixture by carrying out “open-loop” control when the engine is cold or operating under high load conditions in order to maintain engine performance.In addition, when the engine is under normal operating temperature after warming-up, the ECM manages the air/fuel mixture using the heated Lambda sensor signal to handle “closed-loop” control. The closed-loop feedback accomplishes the theoretical Air-fuel mixture ratio where the catalytic converter can obtain the absolute maximum clean-up operation.

Using the Unichip Q-plus you will have total control over these variables to make alterations to the timing and fuel calibrations. The Unichip PnP has 24 RPM sites between 100 RPM and 24000 RPM and 13 load sites between closed throttle full throttle position. This equates to 312 available tuning points for each map. In turn the Unichip PnP is going to interpolate in between each speed and load site 16 times which gives a decent resolution densed map.

UniQ is Unichips most recently released software package for tuning engine ECU’s. This software program is a revolutionary change from old style DOS model which had been in operation for over a decade. Take the Unichip Tuning software for a test drive and see for youself.
