<div class="moz-cite-prefix">So an arming plug becomes the last
resort safety device. <br>
It is not needed if the failsafe is set up correctly AND the pilot
does not turn off the TX.<br>
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.<br>
It is not needed if a motor kill (zero throttle curve, etc.) is
programmed and used upon landing<br>
<br>
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.<br>
<br>
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??<br>

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. </div>
