There have been some carbon copies of those Tornado three blade props.
I am not sure but Eliminator Props by Steven Wilk might have something like that. You might check with him. He is in the Vendor's Corner of this forum.
Also, Randy Smith might know where these carbon copies can be obtained.
I have some of the Tornado props, but would not be ready for anyone to use them. Mine have been used. They are old. They may not be safe. It is the same story whether you are asking about the older grey ones or the black ones that I think were impregnated with either carbon or glass.
