The propellers are manufactured from high quality beech wood in two
versions:
- Propeller diameter from the diameter 12 to 15 inches (300-375 mm) are produced from
solid beech.
- Propeller diameter from 16 to a diameter of 34 inches (400-850 mm) are produced as
prolepované solid beech (glued beech boards thickness 3.8 mm).
This ensures their dimensional stability and higher strength.
