Remember that Futaba, Airtronics, and Hitec 2.4Ghz FHSS receivers all fly perfectly fine with 4.8v receiver packs. Only Spektrum/JR receivers require 6v receiver batteries to help prevent ''brown out'' or ''lock out'' conditions.
Ed while this may be technically true I must admit I do have a problem with the ''perfectly fine'' part. While those brands may be at less risk of brown out than JR/Spek I beleve they are still at a greater risk than what we have gotten away with in the past with our 72 systems.
Reading the Hitec manuals for example it is strongly suggested in sutble hints throughout the info sheets to use 6 volts. They never come out and say use only 6.0 volt but the meaning quite clear.
I use only 6 volts with all my 2.4 ships: 7 XPS Rx's on JR and 8 Hitec FHSS on Hitec and for the majority it does not make sense to do otherwise as well as reaping the advantages of faster servos at the same time.
I always suggest to anyone who asks that it is poor practice to use 4.8 packs especially low capacity type shipped with full radio systems, with any 2.4 Rx. It is my beleif that only 6 volt packs of about double the capacity of what was normally used in the past for 72 system
In other words if you used default packs of 4.8 volts NiCd 600 Mah then use no less than 6 volt Nimh 1200 mah or greater.

Even with 72 I agree with this. I buy the biggest mah packs I can find. I have had that same servo problem with Futaba low end servos even with 4.8. I always put the strongest servo I can get on my rudder, I do buy Hitec but I also use Futaba and JR.
