Oh my!  Someone wants to start a “holy war”.  For the uninformed, the subject of external arming system brings out the beast in some.  One said (and I paraphrase), “I will quit Pattern before I put an external arming system on my airplane!”

BTW, all my competition airplanes have external arming devices.

That seems unsafe to me to have the batteries connected to the motor 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.
