Can't say it exactly, give me another view, take it at the back with the thread nut facing you.

The lower one in you picture has more pitch and looks to be an X442.

The lower one in you picture has more pitch and looks to be an X442.

the fact is that the upper one is a grimracer 42 x 66 and the lower one is a grimracer 42 x 55 , but when i put the 2 one beside the other , i try to see the difference between the pitch , because for me the 66 suppose to have more blade angle than the 55 but they look almost the same ????????? Could someome can tell me how it work ????

Time for kids stuff here,
Go get a play doh clay and make it flat in a plain surface (table or counter) then at the edge put the clay there, then take off your props. from the shaft, press the first prop. to the clay then compare with the other one, that will answer your query I think, but put the 42x66 first then after 42x55, if you have a digital Caliper, on the clay should have your exact measurement.

Oh , ok i will check it, never imagine that it s complex to know a prop pitch :-(

Heads up people when sharpening bronze Beryllium props use gloves and proper breathing masks when making dust paricles,read up on the health hazards, its potentially deadly (not an exaggeration). its the inhalation of dust or getting it in a cut and consequences can be amputation or beryllium disease (lungs) which can be fatal. Now machining is suppose to produce chips not dust, but some dust is created and you certainly don’t want to be abrading/filing it without precautions. I think I will stick with S.S. props
