Yes, there is, but I would like to know for certain which is which.
I tried posting on drones-discuss and the message got rejected, which is awfully frustrating considering the message on the top says the following: This is a public list for discussing the inner workings and proposed changes (i.e. any changes that are not ready for submission to master), arducopter controls, mission planner UI changes, documentation, crash reports from the forums or developers, etc.
Maybe I am missing this in the documentation somewhere?
