Rest assured that most radio manufacturers are already moving in the direction of making their radio gear compatible with the voltage levels common with a LiPo pack.
I do agree the receiver can support more than 7.4V. However I am using Sanwa ERG-VX for 1/8 GP. The documented spec is 6V.. However from what I was told there are servo supporting 7.4V too.
