I just tested the EPIC of the School I teach and it is not hot swapping from AC to REDVOLT (it works the other way around though). I`ll be receiveing my scarlet any time soon and I`m worried it will have the same problem. The RED EPIC Manual says it chooses the between the existing powering sources in a prioritizing order that is: 1 AC 2 Batery module3 REDVOLT on the Side Handle.I would imagine that the shutdown that happens when you pull the AC plug (with a REDMOTE on te Handle) is because it takes the camera by surprise (couldn`t find better words to describe) and it leaves the camera unpowered for a very short moment. So I was wondering if it is not possible to force the camera invert the prioritizing order in user programable key, so you would press the 1 button on the side handle (for instance) and it would shift from AC to RED VOLT even with the AC still plugged. I think that if this was possible, the RED team could implement this feature in a future firmware, it would not be the ideal solution the way I see it, but it would be almost perfect, and would prevent many user to have to send their cameras back...I would like to hear your pinion guys, and would be nice to hear from someone from the RED team too Cheers!
