I am looking for a a way to check the regulator function before or after flight. Aside from an inline voltmeter after the regulator, I am not aware of any such "alarm" on the Smartfly. I did like that the Gemini regulator (although for smaller planes) has a light for each "output" so you can tell at a glance if things are working...

I know I can check the battery with a load test, and I do that before each flight to check the batteries....

I wish Jetcat would just put a small generator device on the turbine so we could just switch to onbard power!
