E-flite P-51D Mustang 1.2m 12 inch 2 blade spinner / nose cone

Should work for the new version of p51d as well. This is a 2 blade spinner for APC 12 inch blade, I only have a 12x6 blade, but it should work for 12x7 or 12x8 as well I think. According to my calculation 12x7 or x8 should provide similar performance as the stock 4 blade. You might need to print the spacer to be placed behind the props, Otherwise the blade will collide with the stock spinner plate.
