Five-blade Composite Prop Boosts Evolution Performance
The propeller is lighter weight and increases speed, among other things.


Evolution Aircraft has completed performance and noise flight tests on a new Hartzell propeller. The composite five-blade, swept-tip propeller increases cruise speed by three knots, adds 144 feet-per-minute to the climb rate and provides 13 percent more deceleration compared with the four-blade aluminum prop that comes with the Turbine Evolution kit.
