I consider it a baseline that is easy to comply with. All the anecdotal evidence in the world that each responder to this list is safe does not help establish a minimum set of standards. Each one of you has a good process that works for you. Each one of those processes could be easily amended to incorporate an arming plug if it doesn't already.<br>> > It isn't those with a good process that are the safety problem. It's the neophyte that hears the experienced pilot expound on why he is safe without an arming plug because he does everything else right. The beginner doesn't hear or doesn't understand all the issues with setting up failsafe, throttle cut, arming conditions, thumb on throttle stick that are part of that process of achieving safe operations in the pits and on the runway whether you have an arming plug or not.<br>> > I have seen models without arming plugs, without external receiver switches and canopies that require two hands to remove. Last time I checked failsafe operation at a contest, full throttle kill was running about 50%. Most of the remaining were simply going to hold which doesn't help at all if you already have a problem. Eventually a setup like that will cause a disaster.<br>> > An arming plug is a small thing to add. It can be done lightly, cheaply and reliably. It provides a visual indication to all that the motor/ESC is unpowered. It is not dependent on any other function in the model to operate. <br>> > John<br>> > <br>> > On 2/23/2015 10:49 PM, Steve Hannah via NSRCA-discussion wrote:<br>> > I agree 100% with Jerry. <br>> > <br>> > The multiple throttle kill approach is the best.

Then, for added security I always hold the stick down with my thumb as my caller/helper retrieves the plane. They usually don't turn off the receiver so I assume my plane is live until I prove otherwise and shut it down. <br>> > <br>> > An external plug is one way, but I fail to see how it provides any more safety than my method. Switching it off from my transmitter and disabling the throttle stick are very secure means and I know the ESC has been shut down.

Usually the pilot reminds the person to do it while they're carrying the plane back or as they're setting it down somewhere. It happens with my planes too and I make sure they switch the receiver off and then I remove my canopy and disconnect the battery directly. But before they even get that far I've taken the other steps to make sure there's virtually no chance the motor is going to run.<br>> > <br>> > My point is this. A layered approach is the only way I've found to effectively mitigate this particular risk to the levels of safety that you claim. Relying on someone to remove an arming plug is not a complete panacea and may lend a false sense of security that the motor system has been de-energized, when in fact it may not have been. There's many ways to manage the risk to the desired level, the use of an arming plug is one, and may not necessarily be the best.<br>> > <br>> > Jerry <br>> > <br>> > Sent from my iPhone<br>> > <br>> > On Feb 23, 2015, at 5:29 AM, Matthew Finley via NSRCA-discussion <nsrca-discussion@lists.nsrca.org <mailto:nsrca-discussion@lists.nsrca.org>> wrote:<br>> > <br>> > I use the Ultra Deans stlye Arming Plug from F3A Unlimited, and It works very well. I would gather it provides you with a 99 % dagree of confidence that your caller , plane carrier , yourself, or anyone else will not be harmed. Yes... I do agree that there is a miniscuel chance that a pilot / caller could forget to unplug the safety, however I feel most pilots that have been doing it a while is like tying your shoes, or etc.... On all of my electrics except for indoor ships, I have some sort of disconnect. I for one would like to see it an inforced rule at all sanctioned meets not just pattern meets, that any plane over a certain size or weight must have one in order to fly.
