A BEC is typically not designed to supply more than one amp to the radio system.
If there are a lot of servos,... (More than two) and features that run off of the reciever power, the
BEC can be overwhelmed, and cause the entire system to get the jitters.
2. And if the main pack is down that low, what good is radio control? You won't have anything to command!
When I run combat, it is always nice to still have control of the guns if your boat should die on the pond.
I may not be able to run away, but I can defend myself, or the tow while being pushed back to safe harbor.
(I have actually had the battery connector shot off the battery... Lousy allie tactic in my opinion...) [:'(]
I usually cut the BEC switch off, and solder a small deans plug in its place.
That way the switch doesn't accidentely get turned on, and I can plug the switch back in
should I ever want to use the BEC.
