I only know the snippets I can squeeze from them.
dates sound like around May of this year for release (at best)
I have requested PID tuning
I don't know for certain about mixer tables but I will request (I just assumed it has it)
I don't have the interface software but I do have the GCS for the zero uav fixed wing. It's really good. I am pretty sure it will use the same GCS.
I have been told it will have the target locking like the uav
I have been told it will have a sonar option for landing
anything else I can ask but can't promise either an answer or guarentee that answer will actually come to pass... you know how it is with these companies
