Hi John,

I guess you are missing one of the most important purpose that power management systems are designed for:

If you have long servo extensions (typically more than 60 cm) and 2 or more high power digital servos on Y connected directly to the receiver you lose signal and also lots of performance. Therefore these channels must be amplified. The extreme high amp loads may even damage the receiver.

A friend of mine just crashed a PCM fitted 1/4 scale model just becuse of this.
