Flybarless Rotor Heads – The Ins And Outs

By blogger on

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.

Are Refurbished Or Recertified Electronics Safe To Buy

By blogger on

The term “refurbished” typically refers to electronics that have been spoiled and returned, then repaired and re-sold by the maker. But the definition is actually broader than that. Refurbish may never have been damaged to begin with. Some are simple returns and interactions. Some refurbished electronics are ready with new cases and batteries, so they externally resemble their new counterparts. It varies by vendor and manufacturer, so be sure to check out the detailed policies before you buy.

Another word may comes in mind is “re-certified.” This usually means that the electronics equipments have been returned or repaired, then tested and settled some kind of guarantee. However, all refurbished products have to be experienced before they can be sold, too. Also, some refurbish have brilliant warranties, while some re-certified products have terrible ones. In general, “recertified” and “refurbished” can be used interchangeably. What matters most is that the creation in question has a good warranty.
This means that they can’t be measured an “investment,” because they lose value over time. To take the car example further, most cars lose 25% to 40% of their value within the first two years. However, a two-year-old car will have lost almost none of its utility. This is why it’s best to let someone else buy new, pay that 40% extra, then sell to you. The same logic applies to laptops and other classy electronics. Very few of us need the latest, most powerful components, and those of us who do can usually stand to want the few weeks or months it takes for the first refurbished models to show up.

But we should be careful about buying electronics used. Laptops don’t have the same lifetime as cars. Refurbished is an improved choice, because of that all-important contract I keep talking about. In general, you should look for a warranty of at least a month or two, to make sure the product doesn’t have any clear defects. Preferably, the warranty should expand beyond that. To once again use Apple as an example, their refurbish come with the same one-year warranty as their new products yet another cause to buy refurbished.
Huge deals can be found in refurbished or recertified stuff. But, you need to make sure that the item will robust your needs. Make sure to study in and do some research on both the item you are thinking of purchasing and the seller. A trustworthy seller will offer a return if the item does not work when you receive it and most times offer some sort of short term warranty. So, don’t be afraid of the words refurbished or recertified on items. They can be a great deal, a super deal, and save you lots of money if you research properly.
Conclusion:
A good tip if you’re thinking about buying a refurbished or recertified item is to ask if it comes with a warranty. Not all manufacturers offer this, but you should ask, and if they do, ask how long the warranty lasts. At the end of the day refurbished or recertified products can be good, you can get great bargains on items that may have little, or no defects. If it wasn’t for manufacturer’s refurbishing or recertifying their products, they would all end up on the trash heap. Buying these products is kind of like buying a recycled product, it is a good idea, and can become a speculation in the long run.
