What size are rhe bullet connectors? 2 mm???

Dear,it's 3.5mm bullet connectors.

what size mounting screws do you use to mount these motors to the frame arms?

M39 M3 Hexagonal Hex Screws 9mm

What size Nuts do these motors use to hold on the props?

Dear,the size of Nuts to hold on props was M6 size.

None of the props I've tried work with this without modification. 1045 is a good size but the axle has flats and is ~8mm in diameter. Are there any?
