YouTube and social media FPV content is oversaturated but still works with a specific niche. What works: FPV travel vlogs, behind-the-scenes "how I filmed X" content, FPV cinematography tutorials, gear reviews, and FPV combined with another hobby (surfing, mountain biking, skiing).
The most successful FPV YouTubers are storytellers who use FPV as a tool, not pilots who film themselves flying in circles. If your channel is just "here's me doing tricks" with no narrative arc, you're in a very crowded lane. Build a channel around teaching, travel, or the intersection of FPV and another thing you're genuinely passionate about.
