Hi Everyone,

In this video I compare a 5inch drone against a 7inch drone and answer the question: "Why do 5inch and 7inch drones behave so differently from a vibration and noise perspective?"

I can't wait to hear what you think of this one. It's a long video so I'll put timestamps here for you guys:

Happy flying!

Chris
