Absolutely. Any machine "talks" claiming or warning about something. Usually using sounds or behavior.

However, there is a area in wich we are usually blind or deaf. One of the best things I did in my rc career was installing a onboard led voltimeter in all my planes. It helps me to see how the voltage fluctuates in the electirc system and this can provide the following information:

1) Low battery voltage
2) Deteriorated battery discharging capacity. (leds go red while while moving the tx sticks)
3) Some dragging/stuck control surface discharging the batteries
4) Moisture/humidity warning (leds act crazy while moving the sticks. this happened flying in a rainy day, after splashing some water puddles on takeoff)
5) Faulty contacts/ switches.
6) Empirical data about rhe batteries discharge curve in your particular plane = how many flights you can safely get without recharging.
7) Warning about bad servos. This saved me a plane recently. While starting the engine, I saw the led bar going crazy.. didnt knew what is was, and shut off the turbine.. moved the sticks/ inspected wires and then everything went back to normal, with one solid green led turned on. However, when I moved the sticks, I felt a difference on the led pattern ...checked everything again and then found that a elevon servo was dead (!)

This humble device helped me a lot, Otherwise, I would had more than one misterious crash,. This also helps to avoid blaming radio brands, model planes, manufacturers, etc.. :-)
