How many players of FPV in USA?

[Mary Yang]

I am interested in FPV. I am studying it and hopefully develop a new and novel FPV model not copy. Now I have some questions for you.

I wonder in the USA how many people have the FPV aircraft? How many people have FPV racing? How many dollars will they desire to spent for a new model?

I think you could know these. It is important for me to know in order to develop new FPV. I would be grateful if you could give me some clues.

Thank you so much!
