The best radio control cars system recommendations

The radio control cars system is quite complex. Yet, it is a magnificent innovation. This is the so-called PCM- probably users have never even heard that a glitch has affected anyone, unless these are so continued to note that the model responds very slowly to the controls, but at this end with the PPM and we would have the model completely out of control.

PPM radio control cars receivers are appearing lately "smart" trying to emulate to some extent the PCM maintaining system security agility almost entirely PPM is the case of Multiplex IPD receivers (which has even stopped making PCM receivers), the MPD Jeti, the Schulze Webra recent recipients. In these receptors, signals are replaced by a shift register chip that analyzes the pulse train and discard any where there are obvious signs of interference (pulse duration of less than 1ms or 2ms more) sending to the servos the last valid signal, and some of these have the possibility of programming a PCM fail safe as. The problem is that some glitches may have duration between 1 and 2 mS, in which case they would deceive the system and come to the servos.

However the security level is much higher than in traditional radio control cars PPM receiver close to a PCM to maintain a much higher speed of response to this.

The receiver that comes standard is PPM? Most people think top models bring the normal version of a radio, which is the R136F, which is PPM Single Conversion. The last number indicates the number of channels, the F means that PPM (if a P would indicate PCM) and the absence of a D before the F means that Single Conversion (if there is a serious D Dual Conversion).

This radio control cars system has an advantage and a disadvantage: The advantage is that the whole process is very fast, so send information from the position of each servo 50 times per second. The drawback is that it is vulnerable to interference.  If we introduce a pulse of noise in a pulse train, for example between channels 2 and 3, the first two channels would be correct, the 3rd channel would send a pulse of noise, and the other channels would send displaced (the 4 servo would send the information of the 3rd channel servo 5 would send the information of the 4 th channel and so on). A split second later a valid pulse train and all the servos return to their correct position. By following instructions, you will be able to deal with any given situation.
