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 class="">> 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 class="">> 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 class="">> 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 class="">> John<br class="">><span class="Apple-converted-space"> </span><br class="">> On 2/23/2015 10:49 PM, Steve Hannah via NSRCA-discussion wrote:<span class="Apple-converted-space"> </span><br class="">><span class="Apple-converted-space"> </span><br class="">> I agree 100% with Jerry.?<span class="Apple-converted-space"> </span><br class="">><span class="Apple-converted-space"> </span><br class="">> ?<br class="">><span class="Apple-converted-space"> </span><br class="">> The multiple throttle kill approach is the best.

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.

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.
