Be interested to hear the collective wisdom and experience on this one.
I intend to operate 10 multirotors. The flights will be auto controlled via mav-proxy and a python script. That side of things is fine.
From a safety perspective, particularly during testing, its always good to have some other form of control. I would like to be able to manually take control of a given drone if I need to.
What have others done to enable safer testing of multi vehicle flights?
