I recently suggested in this thread:http://diydrones.com/forum/topics/need-uav-built-for-under-10k
that Ardupilot would be a low cost way to make a commercial/military UAV.
I haven't used ardupilot in autonomous mode yet, but I've been very impressed with the quality of the ArduIMU.
My impression of Ardupilot is that it is a fully functional autopilot.
I'm curious to get people's opinions: are there any reasons that Ardupilot is not ready for commercial & military use?
If so, what in your opinion are the bare minimum features necessary to a military/commercial drone surveillance aircraft?
