I'd add that, the more consistent the requirement is "disarm the electrical system" the more likely it is that human error is minimized. As a caller, if I know it is my responsibility to arm the aircraft at the flightline and disarm it after landing and there's a "relatively" standard mechanism for that (add/remove arming plug/flag) even if the location of the plug differs and even the specific mechanics. Point being, as a caller I don't have to know any intimate details of how to open your canopy and which wire(s) to disconnect. In just 3 contests last year, I was amazed at the wiring complexity some people have come up with, and on several occasions I was afraid of disconnecting the wrong thing.<div>

<div>What you say it true.</div>
<div> </div>
<div>What I have taken from this discussion:</div>
<div> </div>
<div>1) An arming plug is an externally visible indicator of "ready and dangerous".</div>
<div>2) Turning the rx off alone is not a completely safe condition, and less so AFTER a flight.</div>
<div>3) No safety measure is 100% infallible, simply due to human error.</div>
<div> </div>
<div>Regardless of how you render your aircraft safe, you still have to remember to do it!!! People will forget, and that unfortunately will happen regardless.</div>

<div>Just how many airplanes have we seen fly out of caller's hands at contests? Is this a widespread problem, or just isolated to a couple contests? Why can't the caller maintain positive control of the airplane until the owner gets over to disconnect the battery? If the caller and/or pilot are that distracted after a flight, what is to keep them from forgetting to removing the arming plug? <br>
<br>I think this is a solution wandering around looking for a problem. If you can't remember to disconnect your battery as soon as possible after a flight and to only connect it just prior to flight then you won't remember to use your arming plug to perform the same functions.<br clear="all">
