[NSRCA-discussion] How to safely arm/disarm your motor packs?

[Ron Hansen]

I use an arming plug.

 

One thing no one is considering is that your caller may not know how or have
the correct tools to open your canopy to disarm your ESC.

 

So then you have to trust the pilot and caller to disarm the ESC before they
get distracted by talking with judges or spectators.

 

That is why I like an external arming plug or battery cable on the outside
of the plane.

 

Most callers know to remove an arming plug as they pickup the plane to carry
it back.

 

My 2 cents.

voltage drop which causes apparent power loss.   Ask me how I know this to
be true!!!

position, determined by me which I do program on all my planes even the
jet/edf planes.

without an external physical circuit breaker but I'm probably overlooking
some capability that can be set up using a Futaba 14MZ.  With the advanced
planes that are a little awkward to a carry around armed and where the hatch
has to be screwed into the fuse for extra canalyzer security it seems like
an accident waiting to happen this way.

I'm beginning to think I made a mistake.
