As a beginner Arducopter user, I think an NN application to take off and land Arducopter semi-manullly is great.
In other words a super slow take off indoors or outdoors can allow the new user to learn the controls at an RC and learn the caveats of flying arducopter.
Right now we crash the machine many times before getting a hang of take off and landing.
This idea at the same time will allow us to learn how to develop an NN control system for arducopter as in baby steps.
If we can do that then the user usage of RC can be incorporated into the NN learning, so the UAV is controlled both by the NN and what is learned from the user moves.
