PROMAX propeller do they sling blades too?

[RING21E]

Hi, do you have any informations about the promax propeller regarding the strength?
Any issue with them? no cracks, no missing blades?
Are they really better than the PROET?
Seems difficult to beat the PROET performance anyway, even used ones are sold at high prices even if fast boaters 85mph++ have had issues with them.

I think any prop will shed blades if the blue printing / lab is taken too far.

props come out as high performance then people want to have them taken to an extreme..

to me a mega thinned blade of whatever make is very dangerous..


I always think that the major company's could save a fortune in metal if they made them thin, they are thicker for a reason, longevity and safety.

plus there is also the mega high speed factor if the prop is smashing into the water when run surface .

just my opinion.
