Detecting servo binding with the Frsky X20S (The easy way)

I setup me dash pages for my GeeBee Y so I can monitor a range of telemitary data,

I set up one page to graph the receiver battery voltage. Graphing it gives a very nice display of what is actually drawing current. When you move the sticks you can see the voltage drop in accordance with the current draw.

What is interesting is once the servos stop moving they should draw very little current but if one servo is binding then you will see the voltage continue to remain sagged.

This is a very useful and easy way to check servo binding.
