Got these as spares for the stock ones that came with the OMP Bighorn. Only reason I got them is because the stock prop that comes with the Bighorn did not fit the stock spinner without carving/enlarging opening for prop blade. Never had to do that when using included equipment - shouldn't have to. These need modifying also. Coating (green in my case) chips easily and shows underlying plastic after making prop fit. Shipping was fast as always with BuddyRC
