I would venture to say that there are no beginners out there that are using a true digital servo.
They are are standard now on most entry/basic radio systems.
Where I've seen problems is when a beginner pieces a system together and sales person suggests servos that may be excessive to the needs, yet the battery is basic.
Several times I've come across this and the plane's voltage was unsafe after only two flights.

The bottom line here is that the voltwatch, volt spy, whatever, is a good secondary device and many use them. I do, on everything I have, and rely on them to give me that quick look at battery condition. It saved my plane one time.
I agree 100%, but a voltage/load test meter should be the number one item in the flight box. So many planes I've saved, mostly not mine.
