sound test old and new MP props with original MP

You may want to turn the sound down a little.
Load it, then to cut out the chatter compare 1.30 min in with 1.55 min in.
The newer blades are quieter especially on take off and aggressive ascension.

Would be interesting to hear a test between all three conditions
1 Originally MP with props
2 Original MP with new props
3 Platinum with new props

I bet there is hardly any difference between 2 and 3.
This is no scientific test, just what we hear.

I can't watch at the moment as at work but there have been quite a few threads & videos, some with spectrum analysis, DB meters, different types of flights & distances

I have noticed quite a difference in noise. It may be more a matter of tone pitch than volume. My old props sound more like a hive of angry bees and the new sound like a lazy bumble-bee. I find it hardly noticeable above 100 feet.
