There seems to be a big, big issue with builders frying the APM 2.0.
A good many of them seem to know what they are doing. What is the problem?
I want to know once and for all how NOT to fry the APM 2.0.
It's my understanding that the APM 2.0 needs/uses 5v. It is also my understanding from the posts and submissions from the forums that supplying more or less than the stated 5v can or will cause issues.
Seems simple enough, but then why are guys having a problem?
I'm not a computer scientist or electrical engineer, so I must rely on the kind help and support from others here.
In my case I have a servo that must use 6v because of the torque. My Castle Creations phoenix Ice 50 motor controller is programmable and can supply 5v.
I also have a separate Castle Creations BEC battery eliminator. It is also programmable and can supply 4.8v-9.0v
Now, beyond the 6v servo. I am not running anything special. I plan on using the GPS, xbee and maybe the wind speed sensor.
The question is using a single 4s 5000mah lipo, what is the safe and correct way to wire the APM 2.0 so as to NOT fly it?

You might be best to just get a proper 5V servo. Messing with all that wiring can certainly increase your chances of frying the APM. You could also have interference problems and ground loops and diode burnouts or other problems. I don't think the added weight and complexity of wiring is worth it. KISS right?
It would be a real heart breaker to crash or burn out your $200 APM over a $10 servo issue.
Set everything to 5v and see if you really have a problem running the servo at 5v.
