How much do you want for the X472 prop?
Piro,
The removing of the front leading edge or tongue of the propeller is not a Texas-Cut.
The Texas-Cut is more of a straight cut down the leading edge of the propeller blade.
Along the leading edge that you show in your picture as the (spoon and cup area).
This area will also control your leading edge pitch numbers.
Your trailing edge (lift area) is the area that we cup the trailing edge on in the older style propellers.
Your picture is more of a older style propeller design. Some of the new designs are a lot different.
Your Barr-Cut should be cut at the same angle as your trailing edge surface angle.
You have some interesting (pitch areas) in your picture as well as your (lift area).
Keep Testing And Learning About Different Propeller Designs.
Thanks For The Pictures,
Mark Sholund

Hi Mark,
Thank you for your inputs
The second picture was as like interesting collection on my plate (there can I show, on the black line where I made only the modificaton too)
The blades are ballanced and polished (I have tested it only on Mono and I should change the strut position from 2814/3 -3)
This ABC will send to specialist to win any speed
Robert, if you have interest to buy it the shipping cost with tracking $ 8
Joseph

Joseph,
I would not waste the time on polishing the propellers unless it is for a static model.
Polishing will throw off your balancing unless you continue to balance while polishing.
It will also cause some cavitation on some applications. Another good tip is to have a
metal lathe in your shop with a 3/16” or 1/4” drive dog installed and chuck it up in the lathe
to make sure the blade lengths are even. This will save you hours in the balancing of your
work. Keep up the good work!
Happy Holidays,
