Hi Tom,

In the second half, as you pointed out, if the esc goes to "cut off" if the on-board battery goes dead this in itself is much safer than an IC powered plane. In the IC example the engine is taking the airplane directly to the crash site at possibly WOT.

I'm of the mind to just leave it alone.

I personally have mine set to go to cut off if either happens along with using the "Throttle Hold" switch to kill the power.
