Hello, quick question here:
I have a stock DJI F550 Hex that I am pulling the naza fc out of and using APM 2.5. I understand I need to use a BEC with the 30a DJI ESCs but I am unclear of how I would connect the DJI BEC to accomplish this. I recognize that the BEC is connected to main power and then to the throttle channel on my receiver but where do I connect the other connector from the BEC? Does this go to the ESCs or the APM? There are two signal wires in addition to the power and ground.
The APM is receiving its power from it's power module so I am not sure why I would want to connect anything other than one of the signal wires from the BEC to the throttle input signal input on APM? Is that all I need? I know the DJI ESCs don't have a built in BEC but I am not sure if this wiring arrangement would handle that issue.
Any help/advice would be appreciated.
