PS I have never seen anyone using an ammeter in line or other wise at the field, much less installed in a model aircraft. I'm not saying it wouldn't be better, just saying I've never have seen one used in a model ---------On the other hand I see the I4C in many installations, and it shows the slightest high current draw or low voltage situation --

Lee,
Your comments on the C-Volt voltmeter are correct and many jets now have them installed for both ECU and receiver batterys. We are now testing our new Onboard Current Meter(amp meter). This instrument is the same small size as the C-Volt and will show live current continuously from turn-on to shut-down. See the exact current draw of each and then all servos by exercising them. This product will be ready for sale next month. Will be about $5 more retail than the C-Volt.
