What BEC to use for MMP 1S version?

Never thought of that, although it seems obvious now. The Rx is a Spektrum SR300 and the servo is a stock AE metal gear (for now). I don't care about the servo but don't want to fry the Rx. I figured the 2S LiFe pack fully charged would be too much for the Rx. Time to go check out the Spektrum manual.

EDIT: You are right Thomas, maybe won't need a BEC at all. Most Spektrum surface Rx's work between about 3.5-9V so that will be fine on 2S LiFe. The servo I have right now might burn up, but I can get a 7.2V capable one if I have to.
