This prop is not included in the Airfix kit. The Rotol prop sports a different blade shape with a wider chord. The spinner is the same as provided in the Aires replacement for the kit part QB72 491 reviewed elsewhere on this site. The spinner puts the joints lines in the right place and in the right scale. Be sure to cut the blades off the casting block to allow the maximum shaft length. The spinner holes go through the part and the long blade shafts help with the alignment of the blades. Check the blades carefully because the leading and trailing edges are slightly different shapes and I managed to put one in backwards. The tool also has a hole to center your drill so you can drill out the spinner for a prop shaft. This part is a welcome addition to an already cool little kit.

Thank you Aires Quick Boost for jazzing up the Defiant.
