Good afternoon , one of the above messages had a link I assume is your U-Tube. I like "skybird rx", the only change will be in capitalization "Skybird RX". Review the FAA restrictions on dropping objects, you must be sure the drop is safe!
Devise a new drop mechanism. Develop a NEW drop device with a NEW purpose. Identify a better targeting system/method. I support your utilization of this hobby but you MUST really be sure that when a law enforcement officer asks "what are you doing?" you have a plan. Look up Method of Experiment (MOE) and scientific method to help plan your experiments. You can ask the "5 Whys" starting with "why am I doing this?", why, why, why, why? Each "Why" drills down the test and it's purpose. The MOE starts with "What if I did this....?", Then you guess the answer without experimentation, then you plan the experiment, then maybe set a baseline (altitude, payload weight, weather, etc...) for the experiment. Devise only one variable, Altitude change, payload weight, payload design. Perform the experiment, record the results, identify what works and what doesn't. Document your results, this for you, share with peers if you want.
Mmmm, you got an assignment that will take about six months to do. Never stopping asking "Why"!
Be SAFE!
