Contra-Rotating Spitfire Mk. XIV

This project is based on the few Mk. XIV Spitfires that were equipped with contra-rotating 3-bladed propellers. These nullified torque and provided a 6 to 16% improvement in efficiency, but at the cost of weight and mechanical complexity. In my opinion, they also look fantastic which is why I am working towards building one. The props will be 3D printed as I could not find any available.
