hi guys thought i would give a rover a try, just checked the voltage from my esc , it read 5.74v, im just sure if its safe to plug into the board

If you read the manual, Arduplane for example, it would appear that the optimum board power supply value is about 5.3v. The APM2.5 has a couple of 6v Zener diodes in critical places intended to provide a fail safe for parts of the board but you could end up trying to replace miniature fuses, which ain't easy.
FoxtechFPV have some small variable supply boards that allow you to fine tune the output voltage. These are basically adjustable sBECS. I use one on the basis that a 300 dollar APM deserves protection. Another good reason to use a separate supply for the APM is that ESC BECs are usually a linear device and will often stop delivering the goods if they get too hot. If you are running 3-4 servos, an RX and the APM, not many ESC BECs will hold up under that pressure putting the model and the APM (300 dollars) at risk. So after all that waffle, my advice is to use a good quality 5v SBEC for the APM separate from the RC gear and servos.

I would not do it. Evidence says that more then 5.1v will pop the APM. However I have been known to be wrong from time to time.
