I purchased 3 26x10 Menz propellers from DA and notice that on the flat of the blade, 11.032 inches from the center, there is a small hole. This hole is on both blades of all three propellers in the same place. I don't know if this is normal and I have never seen this on any propeller that I have used. Is this normal? If it is, what is it's purpose?
Thanks

Geistware,

Yes the little holes on the back of the Menz props are normal. It is my understanding, that is how they check the wood for density or hardness of each blade.

Hope this helps.

Thanks, then it must be an automated process and they need to adjust the height of their probe. I can see where it rubbed the surface of the wood before going into the wood.
Again, thanks
