I'm sure it's a great project and a learning experience, but you have to keep safety of yourself and (more importantly) the people/things around you in mind.
Step 1: get a few cheap drones, take them to a remote area, and after crashing a few you'll have a good hang on how to fly them and what they can do.
Step 2: get a drone kit, so you learn what parts go in it, how it's connected, where the fine adjustments need to be done, etc.
Step 3: take the drone from step 2 apart and understand all the bits and pieces and know what they do and work together.
Step 4: make sure you understand step 3 thoroughly.
Step 5: build you own drone from scratch! You now know what you're doing, and can make one that will actually fly and do what you think it should do.
