Eventually you'll want to compare what you see versus what the "pilot in the cockpit" sees. I was trying to fly smoothly but it was a very windy day. On the Gopro, the sound is always muted because of the waterproof case. The wing mounted 808 #16 camera is useful when you want to check a component (if a motor has vibration, if control surfaces are binding, etc).
