Stealth Props proven 25% Quieter

I mounted a new set and I can verify they are 25% quieter…..
Now that one of them, not attached securely, flew skyward by itself and never came back down.

Reminds me of an experience I had at the Grand Canyon. I was watching hawks hovering and rising in the upward drift at the canyons edge when a gust blew my hat off and it headed out over the canyon, maintaining altitude in the rise. That was a few years ago. I believe the hat has not reached the ground yet.

Sorry you lost one; got a good ha ha on the 25% comment. I have found some of the stealth props to be difficult to lock in place. I have taken a drill and just touched the bottom of the hole in the plastic with a bit the same size as the hole. This made my low noise props go on a lot easier.

Could you provide us some info and pic maybe? 25% would be very nice.
By my experiences for the Phantom there is only different (lower) noise, not much quieter.

How did you verify a reduction of 25% ? I noticed a “different “ sound , but not a reduction of 25%
