Design build and fly(DBF) competition is world biggest aircraft designing competition where Student teams will design, fabricate, and demonstrate the flight capabilities of an unmanned, electric powered, radio-controlled aircraft which can best meet the specified mission profile DBF is organized by The American Institute of Aeronautics and Astronautics (AIAA) which is is a professional society for the field of aerospace engineering.  

In the context of Covid-19 pandemic, the mission task of this season's DBF is to design, build and test an aircraft, capable of delivering vaccine vial packages and vaccination syringes. We have been able to clinch the 77th position in the ranking of 110 qualified teams from all around the world, with 66 points for final round which is to be held in Wichita, Kansas, USA physically

I've seen several Arduino automated liquid dispensers circulating the web. I find using Arduinos a bit overkill for this specific project. Arduinos are far too expensive.

I figured using a simple transistor or MOSFET would do the job, which would also drastically reduce the costs
