Let me break down the first sentence: "The world of drone racing and FPV (First-Person View) flying has gained immense popularity in recent years." The word "world" could be replaced with "sphere|domain|realm". "Racing" might be "competition|racing|speed". "FPV" is a proper noun, so leave it. "First-Person View" is a proper term. "Gained popularity" could be "gained|acquired|attained popularity".
