Guys.. the whole dual receiver thing started because we got worried the receivers couldn't handle the current draw created by the ever growing aircraft and hence servo requirements. This turned out to be unnecessary. While I can't speak for Futaba.. I do know the JR 955S is capable of handling a burst of nearly 60 amps.
I only run 1 receiver anymore. I don't feel 2 is necessary.
And to put that 60 amps into persepctive, the folks who make the Emcotec power box wired up a 3-meter plane equipped with 15 digital servos and went flying (3D and precision). They measured a PEAK draw of 26.2 amps as a single spike. Average draw was more like 3 amps. I personally witnessed a JR receiver that was subjected to a torture test that failed at 58 amps continuous. So, as Doug says, the current bearing ability of the RX is no longer a reason for 2 receivers. In fact, it never was. People just did it without a shred of data indicating it was necessary. Sound familiar??

And before peole get started, these power box things are another solution to a problem that does not exist. Once again, people are off to the races without getting the basic data required to understand if a problem even exists before they come up with a solution for it.
