<div>I completely agree with "seeing" the disconnect. Depending on one circuit to protect another seems folly. BUT... An arming plug does NOT allow you to SEE that the battery is disconnected. Period. It's one of the reasons that the rule didn't pass the
committee. Exterior bullets are better... But you still can't see that the battery is disconnected without opening the canopy and seeing the battery. </div>

<br>
I hear there are 10S pattern setups that don't use an external arming plug. 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.<br>
<br>
So for those that know how to relatively safely set this up could you pass on the formula? My new Mythos doesn't have an external arming plug and I'm beginning to think I made a mistake.<br>
