I have a question about the "remove before fly" plug in the ardupilot code. I only see this briefly mentioned in the manual, and only from the perspective of where to solder and what the plug looks like. I haven't found any explanation of what this is for or how it works, and it's not immediately obvious (to me) from reading the code what the purpose and real world usage of this feature should be.
Is this explained somewhere? I tried to do a search before posting, but didn't turn up much of anything besides the brief reference in the assembly manual.
