    WIRELESS TELEPHONE AT WHITE HOUSE
    November 21, 1919 - White House, U.S.A.

    President Wilson used a radio telephone set up on the south portico of the White House to direct the maneuvers of a dozen army airplanes flying over the Potomac river several miles away. His telephoned directions went direct to the flight commander in the air. The instrument was similar to those used by American aviators in France in the latter part of World War I. Col. C. C. Culver actively developed the equipment. He began the project in Aug 1910. No new invention was needed, only adaptation and adjustment of existing techniques. By Aug 1916, he was able to send a radio telegraph signal from a plane. Enlisting expert help from the telephone companies, by Oct 1917, voice messages could be send between a plane and the ground. The system was put into service for military wartime use.

    EDISON'S PHONOGRAPH
    November 21, 1877 - New York City, U.S.A.

    Thomas Edison announced his invention of his "talking machine" - the tin-foil cylinder recorder that preceeded the phonograph. He appears to have envisioned it as a business dictation machine. In Sep 1877, he wrote that its purpose was "to record automatically the speech of a very rapid speaker upon paper; from which he reproduces the same Speech immediately or years afterwards preserving the characteristics of the speakers voice so that persons familiar with it would at once recognize it." The indented tin foil, however, would survive only a few playings. By the first public showing of a phonograph, which took place in New York City in early Feb 1878, its practical applications had not yet been realized.

  • A Change is Gonna Come
    by Meredith Grey

    "...Change; we don't like it, we fear it, but we can't stop it from coming. We either adapt to change, or we get left behind. It hurts to grow, anybody who tells you it doesn't is lying. But here's the truth: Sometimes the more things change, the more they stay the same. And sometimes, oh, sometimes change is good. Sometimes change is everything...."
  • All of us have a God in us
    by Earth Day, Kenya

    "...All of us have a God in us, and that God is the spirit that unites all life, everything that is on this planet. It must be this voice that is telling me to do something, and I am sure it'as the same voice that is speaking to everybody on this planet at least everybody who seems to be concerned about the fate of the world, the fate of this planet.

    about Stolen On New Year's

    More vehicles are stolen on New Year's Day than any other holiday throughout the year. (So does that mean thieves are having their last fling before changing their ways or are they trying for a big score to start the New Year?)

RC hobby, which is taking up RC toys as a hobby, can entertain and give you a fun-filled experience. These RC toys are taking the spotlight for a great hobby, not only for kids but also for adults. It's never too late to try one as more and more people are getting into this kind of hobby. Amongst the various types of RC toys, RC Helicopter is the most popular nowadays.

With the ongoing of the technological enhancements, flying a RC helicopter is fun and very affordable. With only about $60, you can have your own dream to fly a RC toy. Another benefit of an RC hobby is that these toys do not release harmful fumes than the other helicopter models and types release. Thus, the pilot and the onlookers will always be safe from harmful chemicals. It's always said that it's easier to fly than any other models. Most RC helicopters are ready to use and fly after the purchase; you don't need to assemble anything anymore.

The usual RC helicopter needs at least four controls. One is called the Roll or the Cyclic Pitch, the Elevator control, the Rudder, and the Collective Pitch or Throttle. You can then control the height of the flight, the steadiness of the course, and some experts like to do an acrobatic control with their RC hobby crafts. RC toys are best played in an open field where you can observe their every move and route. However, RC Helicopters are better than RC airplanes because helicopters don't need a runway to fly, you can definitely fly it anywhere, even in your backyard or inside the house.

The care and maintenance of this kind of toy is not as complicated as you think. It is a technical hobby so you also have to learn some technical tips to better care for your RC toy. The battery life is an important thing to know how to stretch the limit. Before charging it again after it drained, let it cool down first for about 15 minutes before hooking it up to charge. In this way, you will help the battery have a break and not overuse it. Before using the toy, make sure that the screws and bolts are secured in the proper places to avoid any unexpected accidents with your RC hobby craft. If something is not right, like the presence of a weird sound that you have not heard before, you have to stop using it and have it checked first with an expert to avoid sudden breakdown of your RC toy. And when keeping the item, put it in a place where it is wide and has enough room for your helicopter to prevent scratching or unwanted pressing on the item.

There are many types of RC helicopters to choose from if you want to buy one. The Mini RC Helicopters are the smallest, inexpensive, and very durable. It's better to start with a smaller helicopter first as you begin to practice to control the RC toy. The Coaxial Helicopters are more complicated to control since it has 4 channels to control. This one is good for those who want to develop a hobby for flying helicopters. If you've already developed a flying skill, then the 3D Helicopter is the one for you, since it can perform a lot of new tricks and acrobatic moves.
