Hi Dan,

Sent you an e-mail a bit earlier today. After reading the other posts on the twin sync units already built, it gave me an idea.

One fellow mentioned the Safety Sync system (and I think he is correct that they are no longer being built), and that it had the option of switching on a strobe light in the event of engine failure. I thought this to be a good feature.

Why not go one step further, and have it send a signal to indicate which engine had failed? Using the engine's rpm sensor, the missing pulse could trigger the circuit. The lights could be mounted flush in the bottom of each nacelle or engine cowl so as not to be noticeable (not to detract from scale). And, the presence of either engine's failure signal into the unit could feed a signal to trigger a tail strobe for extra visibility if desired. If the pilot saw the tail strobe flash, he would immediately look to the engines to visually tell which side had failed.

Regards,

Al Parry
