I just connected my receiver and servos to my ServoStation, and all the servos went crazy. What is going on?
In the absence of a valid transmitter signal, PPM (Pulse Position Modulation) receivers will decode background RF noise into full amplitude digital nonsense, and mindlessly output this to the servos. The servos will attempt to comply with these random instructions, resulting in violent and sometimes destructive (to your aircraft) movements. A ServoStation won’t stop garbage from reaching your servos; in fact it makes the problem worse by providing 6 volts and plenty of current for maximum destructive power. The solution is to always switch your transmitter on before turning your receiver on, and vice versa when turning things off. If this is not possible, then disconnecting your receiver from your ServoStation will also prevent garbage from getting through to the servos. IPD (Intelligent Pulse Decoding) PPM and PCM (Pulse Code Modulation) systems suffer less from this problem (having traded some response time for improved noise immunity), but it is still good practice to have the trans
