Ok, not really all that exciting, but just my house at 365' above. I was doing a flight test and could only go out about 1/2 mile due to electrical interference. I returned the craft back. The props are definitely audible at that height with the basic white street noise going on. I was surprised about the sound as I would like to be more stealthy. I used this pic to pull a permit for a fence today. worked perfectly! I am the spec in the yard. Proof positive that you really can't recognize someone at that height. Property is 1.1 acres.
