At the time I was running a YS and a Jaccio regulator. I agree that the Electric setup pulls a lot less than the YS did, but the regulator still has to drop the voltage quite a bit in the 5.1 v version. I know it was going into failsafe because I was running a JR 921 and if it loses power the Led's flash when the power comes back. They were flashing when I landed and the regulator was very hot.
