I bought a refurbished P2 from 1UAS and with it came a set of these props. They are grey in color. They are marked 9450 and nothing else, but the bag they come in is marked E310 9450L Thrust Boosted Prop.
Here is the funny thing, I decided to weigh each individual prop and came up with no two props weighing the same. I reload my own ammo, so I can weigh things in grains or grams, so decided to weigh the props in Grams.
Four grey props. Two were CW and the other two CC.
CW 12.72 12.72
CC 12.71 12.70
Four white, gold tipped props for a P3. 9450's
CW 12.85 12.84
CC 12.59 12.24
Four stock 9450 props never flown.
CW 12.00 12.31
CC 12.18 12.49
FYI, none of the props weighed had been flown.
I will let you draw your own conclusions on this weight thing with the props. It would seem to me that from what I can see, the Grey Turbo Thrust props were the most consistent in weighing the same. There were some pretty good deviations between the others and that is then up to you to decide if the difference in weight is significant enough to warrant your further consideration or action. Do you use a dremel to grind off some plastic around center point and then reweigh the props to try and get them all the same.
I do know that when you spin anything, the weight involved is important.
