I would add more dynamic motion to the props by curving the blades and making the end like a 'whipsaw' with a tapered end. But thinking about this 2 things come to mind; the Tempest is moving at 400 mph and is obviously a much diff aircraft.
This is an effective method as I watched at shows guys doing double takes thinking the prop is spinning!
I'll think about the diff here , wooden prop , slower speed. Still concerned about the heat generated , how will that affect rigging , and thin clear prop blades, hmmmmm....
