Measures for E-wave losing contral

一.What is losingcontral, the reasons

    So called losing contral means the remote controled model going out of control, in such a case immediately calling should be made to cause attention of all persons on site to find a safe position to avoid injury.
    

The reasons comes from many aspects, commonly as:parts looseness,malfunction of E apparatus, E waves interference in same channel,insufficence of emitting, etc.

二.Mistaken area
1.Special frequency?
    

Some veterans like to adopt special channel for his models, thinking this channel is only one hence not like to ask or tell other people his channles; in fact in views of wirelss electronic waves, there is no so called "special channel", mutual interference may occur when similar waves coming together.

2.No interference for advanced apparatus?
    

Remote controller being saled on market works on AM/FM(PPM)/PCM, generally six-channel apparatus when matching PCM reciever can be digitally modemmed, increased ability of anti-inference can be obtained but possible interference also occurs;

3.My characteristic

More than a half of domestic model friends have not paid enough attention on the right use of channel flag, ribbon is often tied to the antenna of emitting device to see the direction of wind (sometimes no strips), in fact channel flags are mainly used to tell the different channels by it's distinct colours in addtion to observing the direction of wind, please notice that some colourful flags can no longer be used.

三、Measures
1.Careful check/test of device
    

Sufficient or not of the battery on the device should be carefully examined before every flying, so do the every pole,helm and gemel, whether or not is the receiving antenna drew out of the body and in straight, examine the ground effective distance for remote control without the drawing out the antenna, ensure it nomal in rang of 30-50 meters.

2.Frequency at mouth

a big part of freshmans don't know how their device is modemed or even the frequency,they usually begin work as soon as they reach the site, interference sometimes caused; in fact remote controlled flying models are very suitalbe for colony games, knowing each other's frequency can benefit the safety and friends making, why not do that?

3.Frequency registration

Frequency bulletin for enquiry, enrolling the frequency on the site is often used in few places, there are few professional sites in home land, fans like to go to open place for the flying, there is no big problem when the number of peoples is less, otherwise a chief should be selected in charge of the enrolling of the frequencies.

4.Use in harmony
    

Whenever the devices in same frequency are used, good comunication about flying schedule should be made one another, hailing before every starting of your device to avoid the happen of accident.

5.E-wave inspection
    

There are specially made electricity wave apparatus to inspect the frequencies being used in normal games.
