Pixhawk to be used for telemetry only on RC boat?

Hi community,

I have a situation where I would like the Pixhawk’s ability to log inputs and provide situational data (location, velocity, etc.) via telemetry but I do not require any automation nor do I require the flight controller to take control of any of the inputs.

Is there any reason why I could not splice the output from the radio receiver to go to both the servo/esc and then the flight controller to achieve the results I am looking for?

What triggers the start of APM controller logging of flight data?

I made a schematic to explain, hopefully it uploads.

Thanks in advance,
Neil
