4 blade prop
The right size prop will not look scale. You are looking at a 14x6 or a 14x7 four-blade prop on a 1/7th scale Mustang. The prop will look too small. This prop will look OK on a .40 size Mustang but not on a 60 size Mustang. If you want to swing a scale 4-blade prop, use either the RCV 90 or the RCV 120 four stroke.
