5 blade FMOD?

[Josh M]

Hey Tom, quick question (kind of a request though haha).

Have you considered doing a sound pack specifically for the 5 blade version? I'd love to see that for it, I think it would be icing on the cake for this bird

TBH I have not, for a few reasons.

1. The engine (as opposed to prop) sounds totally dominate when on the ground, so I haven't distinguished much of a difference.
2. I haven't found a really good 'side by side' comparison of the differences between the two

MU2 are rare enough birds, that we get our perception of sound mostly through YouTube Videos and in those cases, the wind direction can have an effect on how the sound hits the camera microphone....so REALLY figuring out how a 5-blade vs a 4-blade really sounds across the entire operating range has been a challenge.  Usually you just get some "taxiing" videos.

Most folks absolutely focus on the loud whine/howl of the engine...that's their recollection of the Garretts sound.

If I had a really goood 'sound data' of both where I could hear the distinction across the operating range....and was sure the distinction was due to the 5-blade prop itself (rather than other, recording or environmental factors like echo/reflection/wind), then ceratinly I'd consider it.

I’ll see if I can find something with the 5 blades on the Garrett. It’s mainly the prop “rip” per se.

Tom,

doing a flight in it now and browsing for some decent YouTube clips etc of 5 blade garrets. Here’s a few I’m finding (including an MU-2 internal). The 425 video has same engines, biggest difference you hear is the pitch of the props, being higher since you’re hearing 5 blades per rev vs 4 blades per rev. Can hear same thing in PT-6’s as well.
