When using complex techniques to develop an electronics outcome you need to keep in mind a few things:
Using appropriate resources and techniques to develop a functional electronics outcome
Constructing, testing, and analysing functional circuits to ensure that the electronics outcome performs to specifications
Testing, modifying, debugging the outcome
Explaining the behaviour and function of the electronics outcome explaining relevant communication protocols
Addressing relevant implications.
Use the blog to make some decision and then design the most appropriate use of your drone. I recommend the aspect of SAR package delivery as the best starting point as this can be easily tested.
