The only arming mechanism I have used is the MPI arming plug with dean's connectors. I'm curious about what others are using?

Keep using the Deans plug.  That way I can borrow a plug from you when I lose mine.

That's not the worst place for a Deans connector.  The male part is what fails, so it can be inspected and replaced easily. It can still fail in flight, though. There are more reliable connectors. 

How do they fail Howard?

Is there anything wrong with the XT60 connectors?

The single spring leaf breaks off one of the conductors of the male connector.

Thanks Howard

In my opinion - nothing wrong.

I used XT60s for my connections.

Question, how many people secure the arming plug with a leader attached to the fuselage to prevent it from getting lost in flight?

One XT-60 set between the battery and ESC, no arming plug. Plugging the ESC to the battery is the "arming". Use XT-30 and XT-90 for other applications. Collect all your Deans and line the bottom of your garbage can with them.

That is how most of us do profiles, but a full body needs to have a plug for logistic reasons.  The time on the circle hooking up the battery and unhooking it after a flight is a bit of a problem at contests.  With the plug out the electrical system is dead.  By simply hooking up the battery you are arming the plane and at a contest that means someone is holding it.

Hi Steve,

I have a leader attached to my arming plug to the fuselage. But it's not because it might get lost in flight, rather that it might get lost when someone disarms my plane "after" the flight. They seem to disappear or go missing. If I had a dollar each time someone can't find their arming plug I be...
