I saw last week that Lockheed has announced the release of a new quadcopter called Indago VTOL Quad Rotor.

They've got price sheets posted. It seems overpriced but what I found interesting in the specs is how quiet it is.
Whisper Quiet - 62dB at 3m, 52dB at 10m
At 10m distance, the acoustic signature of the Indago is comparable to the hum of a refrigerator.

I own a Vision+ and it's loud. Are there aftermarket props that are quieter?
 
It's an 800+mm quad; it's going to have low kv motors with huge props, so it'll be a lot quieter than a phantom.

Obviously shot in the USA. Here is what I want to know: did Lockheed get FAA approval and a certificate to fly that thing for their video. It's certainly a "commercial" use, no?

:roll:

Well pretty much any prop with a lower pitch will be quieter than the same design with a higher pitch. It has less "bite" so it will naturally be somewhat quieter. However the trade off is reduced performance.

U.M.
 
Well if they're made by Lockheed Martin and used for government purposes, then yes, we are already buying them. My guess is they're in the $10-20k range.
