It's just one of many options, but do you put your heart and soul into something then not let it see the light of day after you find out you can't profit?
fpvracing has already worked for free: spent effort to design a product, without any revenue, and apparently now having given up hope of getting any revenue.
I made two suggestions: one of which might provide a path to revenue, and another which, whilst providing no revenue, would also cost nothing, and require virtually no additional effort beyond that already expended.
Do you work for free?
