Got to try the Hover 30 X 13 today for 4 flights.
Sorry that I have no video, since I was by my lonesome.

Idle of 1780 rpm and a WOT ( on the ground ) of 6320 rpm.

A noticeable higher landing speed over the Vess carbon 32C.
A faster WOT level flight ( almost scary ).
Down lines are faster.
Hover pull out is not as good.

Now for the noise.
1/2-3/4 throttle is quieter, WOT up lines are quieter, BUT........ WOT in a level flight is actually louder then the Vess.
When it rips, it is a different tone then the Vess and it almost hurts your ears.

I'm gonna stick with the Vess and use the Hover when I fly places with noise restrictions.
The Vess is already ripping at 1/2 throttle, where the Hover is still not ripping yet.

OK, got the wife to go take some video.
1st things 1st, she takes excellent videos, but I got a new camera that does not have an eye piece ( just a screen ) and she couldn't take the video like before.
I guess for airplane recording she will have to use the old camera.

So, the videos clips are for noise reference only.
I performed the same flight pattern.
Tonight was a little hotter and more humid, which seemed to keep the sound down some.

1 video is the Vess Carbon 32C, followed by the Hover 30 X 13.

I feel the Hover is less noisy at lower rpm over the Vess, but at WOT it is definitely louder.
I don't care for the down line speed and landing approach speeds of the Hover.
I like the way the Vess slows down.
But each to their own.
Just posting some info / findings.

What do you think about going with a bigger diameter and less pitch, maybe a 33 B or A in the stealth line ?

LOL just noticed that 32 was the biggest they got, oops.

I actually really, really like the carbon 32C.
The only thing I would change is a little ( very little ) more spool up and less noise.
Other then that I love it.
Super slow landings, slows the down lines down, great pull out of a hover, and stump pulling power.

Normally bigger diameter and less pitch will be noisier. Bigger diameter props cause the tips go supersonic and rip. To reduce noise you'd want less diameter and more pitch.
