x445 cut down to 41?

[jkr]

Is there any way to detertmine the pitch of a prop?
I have a used x445 and i cut down to 41.
How much will be the pitch?

[dasboata]

stock pitch 2.478 but the pitch ratio goes up

Goes up like 1.5x41-1.6x41...?

As said the pitch remains the same as your only reducing the diameter & not changing the angle of the blades, re ratio it would go from 1.4 x 45 to around 1.53 x 41.

So.
Now the prop is 1,4x41 correct?
If i wanted the pitch from the 45, i had to change the pitch to 1,53.Correct?

Hehe.
That's i'm going to do!

What is ''pitch ratio''?

[Chilli]

The ratio between prop diameter and pitch.

For the 445:
Diameter: 1.77" x 1.4 pitch ratio = 2.478" of pitch

Now take the 2.479 (since pitch remains the same) and devide by 1.614"(41mm) and you come up with a new ratio of 1.535 (assuming I did my math correctly)



So Chris. Any potential problems with decreasing a props diameter significantly?? I've been told prop walk could be a problem with some props??

You need to buy a prop gauge to measure the blade's. Or just like the man said just put it oon and run it, try another machine it rebalance it and try again. You can only make it better or worst......keep it fun.

Most likely you would get more lift because you change the shape of the prop I doubt prop walk would be any different I would not go any higher then 1.7 Pitch ratio

[dasboata]

Hehe.
That's i'm going to do!

LOL I knew you had no clue anyway JHF

Yes.
It's my first customized prop.In general i ballance them and make them razor sharp.

Just busting chops,,,, everyone starts somewhere Octura's and props are pretty toxic so wear a mask and some safety clothing !!

When working on props and belt sanding make sure to use the shop vacuum conected to the sander to suck the dust away from you. I wash my hands often also when doing detail prop work. Hey just like anything else........ light fuse and get away fast Ha.

I always use protection hehe.
I have to buy a belt sander cause i spend to many hours on a prop.
