The numbers show only one part of the complete comparison.

How much static thrust the propellers develop? The RPM alone shows only the tip speed and not the "bite". Like the Vess o-la la - they turn faster up and have higher rpm's then anything else but their thrust numbers are way in the basements. Good for very lightweight 3D airplanes but NO good for Warbirds.

One tip to balance the prop hub, use hot glue for larger propellers. And/or, if you "see" the prop is pre-drilled wrong sent them back...

Happy landings
