Re: I'll add a light to my drone...
Come on, at least follow the tradition.
The Morse code should say: "Your Mother Was A Hamster" while the drone "Farts in your general direction".
On a more serious note - the beacon consumption is marginal compared to the rest of the package and the wi-fi bit requires virtually zero additional power/battery expenditure for a WiFi controlled drone. As far as proposals go this one is not entirely unreasonable technically.
