[&o]working on this theory,, i would sure think a prop would aso need a spar???cetrafugal forces aside.did you take note ,that most ,if not all ,wing spars do not go to the tip of the wing?? also they get smaller.. even in a non taper wing..remember the term, main arodynamic center??
I do not understand your reference of a prop needing a spar?
If a wing spar does not go to the tip of the wing, what supports the ribs?
Main areodynamic center Explain what that is please?
