The motor will have a threaded shaft or prop adapter, a washer and a securing nut supplied usually. Cheers

Take the thick threaded piece and using the 3 black bolts provided attach it to the end of the motor with no shaft. Use a little Blue Loctite on the bolts to stop them vibrating loose. put your prop on the threaded part them the washer with the flat side towards the prop and the screw on the spinner (cone) The small hole in the top of the cone is to insert a small screwdriver to help tighten it up. Good luck

The finer pitch(10x4.7)will give you higher revs and better climb but slower top speed and the courser pitch(10x5)faster top speed less revs and less climb.They are so close the difference will be minimal. Cheers

While Benny is correct, the 10x4.7 are normally a slow flyer prop and have a wider blade where the 10x5 is a thinner blade, I'm not sure I agree with the less rpm and less climb thing though.
