Sorry guys I'm not buying it. There are too many variables to accurately say which one has the more favorable odds of protecting the general public. That is unless either of you have accurate data. Perhaps this falls under what would be best for the flying site. Since the flying fields that I frequent are well away from the General public, there is virtually no risk to them should a loss of signal happen. The risk is to the participants at the field.

Now that being said, an actual failsafe event is quite rare. Most out of control situations are battery related with linkage failure being a close second. A Brown out is not a failsafe event. Since failsafe was introduced I have only had 1 failsafe event which I had all surfaces to neutral and engine off. The airplane glided into a hillside and was destroyed. However if flying a small model in a residential zone with minimal overflight to reach houses then the " all in " method my be best.
