Im getting a Raptor 50 and bought a tail servo that is 4.8V.Is it safe to use a 6.0V 2500mAh receiver battery to run it?or does it have to be a 4.8V battery?I wanna buy one of these set of batterys but not sure what ones to get?

Just get the 6v battery and use a step down voltage regulator like this one between the receiver and gyro.

.Will the swash servos be fine at 6.0V,there hitec digital servos but im not sure if there 4.8V or 6.0V (dont have the heli yet and cant remember the numbers)..

The servos will probably be OK at 6 volts because when you charge a 4.8 volt pack they usually charge taht high. The problem with 6 volt packs is they usually charge to over 7 volts. Bottom line is if it specifically says to use only on 4.8 volts don't use a 6 volt pack. Personnaly I would use a good 4.8 volt pack and use servos with the ratings you need at 4.8 volts. That's what I do.

I use a Castle Creations BEC. You can program it to step down the battery voltage to just about anything you want. I'm using a 3s battery (11.1v) and I can choose to run my system at 4.8v or 5v or 6v with my Futaba GY-401 and Hitec servos.
