Picture of A CHEAP RC HELICOPTER
Flying RC helicopter is really very exhilarating. Their versatility gives a RC pilot a complete access to the three-dimensional space in such a way that no other machines can! I have played RC helicopter for more than one year but still find that I have just learnt a few tricks that it can perform.

There are generally two micro-helicopters ( indoor ) in the RC market. I have already planned to buy one of them as they can fly inside the living room and even take off on ours hand. Unlike those operated by gas, these electric helicopters are very clean and give out no terrible noise at all. In one nightfall, I visited a web site, which is about how to make a hand made RC helicopter. I was totally impressed and started designing my own helicopter. Here is my helicopter:

Step 1: MAIN BODY

1.The material that I use to make the main body of the helicopter would make you feel surprise. It is the circuit board ( after removing the copper layer ) that purchased from electronic shops. It is made of a kind of fiber which gives abnormal strength to it.
The circuit board is cut to the rectangular shape as above( 98mm*12mm). As you can see, there is a hole on it which is used to house the main shaft holding tube as below: (2)
Brushless DC, Brush DC, And Stepper Motors From Allegro.

Step 2: MAIN SHAFT

Picture of MAIN SHAFT
The main shaft holding tube is made from a white plastic tube (5.4mm*6.8mm) and two bearing (3*6) are installed at both ends of the tube. Of course, the ending of the tube are first enlarged in order to house the bearing firmly.
Up to now, the basic structure of the helicopter is completed. The next step is to install the gear as well as the motor. You can take a look at the specification first. The gear I used is from Tamiya gear set that I bought long long time ago. I drill some hole on the gear in order to make it lighter and have a better look.

That's not your project.

The logo behind the helicopter is from Militar Police, from Sao Paulo, Brazil.

You picked it up from somewhere.
