Wooden propeller Wolner 2100mm for Rotax 912, 914, 915is

I am selling a wooden Wollner propeller with a diameter of 2100mm for Rotax 912S and 912ULS engines and thicker Rotax 914 and 915 is. Possibly for radial engines. Propeller is more suitable for replicas and slower aircraft up to 150km/h. Propeller thrust is great. The pitch of the 6 clamping screws is 101mm about 4 inches. The propeller has a Central centering hole according to the Rotax flange and also a recess for 13mm shear bushings. Glued together from eight pieces of battens. The propeller is undamaged and fully functional. It has flown only about 15 hours. My 1.2TSI engine has a higher torque of 210Nm and the propeller is too light for it, or rather the turbo takes up later and I don't use the full torque at economy rpm.So I have hung it up and replaced it with a three-blade propeller with a diameter of 2000mm.The price for the propeller is 12000Kč.
