Static thrust for the actual operation is important only when taxiing for takeoff site.
For a real airplane in the first place is important aerodynamic efficiency of the propeller, its ability to maintain traction in all flight modes.
Hungarian pilots recently installed some new saber propeller diameter of 1600 mm (63 ") on their trikes with engines Rotax-503 (2.58).
They were 2-bladed wooden propeller.
Thrust increased from 125 kg to 159 kg.
American pilot went even simpler: it dismantled three straight blades of the hub and set new saber with the same diameter 63 "
Increasing the thrust due to the replacement of the blades was 25 kg
Engine - Rotax-503 (2.58).
Thus all observed pilots better retention in flight thrust.
Scimitar-shaped blades are more expensive, more difficult to manufacture.
But this is the case when a new blade is equivalent to setting a more powerful engine.
