Ultra-Prop 1 vs Ultra-Prop 2: What is the difference?

The Ultra-Prop 1 is the original design, featuring a simple but effective airfoil, and is available in diameters up to 59″.

The Ultra-Prop 2 is a more modern airfoil with aerodynamic twist and carbon reinforcement. It is available in diameters up to 66″. For a given diameter, you won’t see a dramatic difference in thrust between the two. But with the larger available diameter, the Ultra-Prop 2 has the potential to absorb much more horsepower.
