Also, ONLY 2 blades. VW's don't like 3 blade. Again it's the harmonics that snaps the crankshaft. John In a message dated 3/28/2017 10:23:44 A.M. Mountain Daylight Time, [email protected] writes:
To echo what Steve said, the rigidity of the carbon fiber blades on the IVO prop as well as the Warp Drive props are known to cause harmonic vibrations that are detrimental to the life of the crankshaft in that the harmonics can cause crankshafts to crack and eventually fail. It is strongly recommended to use wood or wood core props only on VW conversion engines. Of course with Experimental Aircraft, you are allowed to build contrary to recommendations. But please be aware of the potential issues. -Jeff Scott Los Alamos, NM ---------------------- Unless something has changed IVO props are not approved for a VW engine.

The 2100D required a ~6 inch extension to the cowling (top and bottom), a custom internal exhaust, new mount, modified intakes, and a new adapter for the IVOProp. It's getting there. Totally new look with the longer nose and no front exhaust stubs. > > Tristan _______________________________________________ Search the KRnet Archives at https://www.mail-archive.com/[email protected]/.
