The ICM Do-217N-1 is a nice kit but it could use some updates. One of the big ones is in the propeller blades and prop hub. The kit offering is not quite correct in shape and the prop blade profile is off slightly with the propeller tips being a little too pointy.
Quickboost recognized this and offers up this easy and convenient prop set. Included in the typical resealable bag with card stock backing are eight propeller blades and two spinners. The only thing missing is a tool to set the angle of the blades. Removal of the parts is simple enough. You will have to drill a center hole to mount the spinner with the props installed. This will require some brass, not included, or some other form of support. You could always just mount the prop spinners directly to the cowlings.
