RE: AR9100
Did you not read the explanation just before your post? The soft switch that comes with the 9100 still allows a small amount of current to flow even when its in the off position. Its been said if you don't fly often enough this small drain could pull your battery down to an overdrained condition which is bad for A123's and could ruin your battery. The sure way to avoid this is to disconnect your battery from the RX. Just turning off the soft switch won't stop the small current flow, but if you substitute that mechanical switch with the Arming plug, you can effectively cutoff/disconnect the battery without ever having to go inside the fuselage by simply pulling the "key". Sure the included soft switch defaults to the "on" position forsaftey reasons, but the arming switch is almost like not having a switch at all .. and simply connecting the batery straight to the RX. Now thats .... eliminating a potential failure point, and safe guarding your battery investment too! ... provided you simply pull the plug before storage.
