[NSRCA-discussion] Fwd: Contest board - Was Executive Board voting

[Randy Forbus]

Ive discused this with a few people, if your batteries are not pluged in then thats you arming plug or should I say unarming plug,  Im new to electrics and had to learn a whole new ball game, I know those props wont slow down till they hit bone, I always disarm the batteries when I land and clear of the runway. People make mistakes we are all human and we learn from them, hopefully that guy who turned off his transmiter wont make that mistake again.

So an arming plug becomes the last resort safety device. 
It is not needed if the failsafe is set up correctly AND the pilot does not turn off the TX.
It is not needed if the ESC operates correctly (kills with no signal or no power) AND the TX OR RX is not shut off before disconnecting the battery.
It is not needed if a motor kill (zero throttle curve, etc.) is programmed and used upon landing

So then if none of the above corrective actions fail, THEN the arming plug will work, but ONLY if the guy who forgot or failed to do all of the above also remembers to pull the plug. Yes, I know, others can see the plug, but if the administrative control of requiring proper failsafe and ESC operation is required and enforced, then that eliminates almost entirely the potential for an accident of this type.

Which brings up the question of just how common this type of incident actually is. Given the number of practice and contest flights in a given year just how often does this type of thing happen??

Well didnt stupidity happen when this pilot turned off his transmiter?  Im sure he wasnt thinking, arming plug wouldnt have helped in that case, and you sure cant blame the equipment if its no set up properly.
