This video has action cam footage, audio, and stick movements. Can you guess the drone size from just the footage?

So did you guess too big, too small, or spot on?

I guessed half an inch too small.

I was sure it was 5 or 6. Is this video sped up?

When I saw the video, it looked like a larger quad to me too. I don't think it is sped up but not sure, maybe just down to the pilot's flying style?

its crux35 written on the vid, isnt it 3,5"?

Judging on the video recorded performances of my two Babyhawk II HD with a very high "C" rated 850mAh 4S so under 250g I guessed it wouldn't be a std 5" so likely a well tuned up 3.5", maybe a hot 4". There's very little to choose between a well tuned 3.5" and the average 5" these days.
