In my humble opinion......

By DEFINITION, an emergency shutdown system that introduces a delay AFTER THE PILOT HAS RECOGNIZED AN EMERGENCY and COMMANDED A SHUTDOWN, will in and of itself INCREASE the RISK OF FIRE...there just is no other way of analyzing it as far as I can understand. One may argue that the increased risk of fire is slight, but that does not counter the fact that the CHANCE OF FIRE IS INCREASED.

As for comparing the delays associated with this scenario (ie the inevitable human reaction time delays associated with a PILOT COMMANDED EMERGENCY SHUTDOWN) to the delays imposed on a DELAYED FAILSAFE SHUTDOWN......I believe the point is valid...

Introducing a delay at failsafe does indeed INCREASE the chance that a model will hit the ground with the turbine running. The problem is, almost no one I know was setting the failsafe to instantly shut the motor down on a failsafe event, as the normal TX/RX system could not FILTER OUT THE SHORT, LOST FRAMES inherent with a modern PCM system.

If one advocates a rule that all turbines must shut down the INSTANT that there is a (recoverable) failsafe event, then so be it. I think most people (TRC/JPO/members in general) do not want this.

On the other hand, to burden these same users with a delay in their PILOT COMMANDED EMERGENCY SHUTDOWN, with an attendant INCREASE IN THE RISK OF FIRE is in my opinion not a good trade off for the overall safety in the hobby.
