I was one of the guys who got hosed on the Engineair deal. I've been trying to sell the MT 5 bladed propeller that was used on the V-8. I've a prospective buyer who has bought a IV that is already flying with the 550 and he wants the 5 bladed MT on it. Does anyone know if this conversion will work? The prop is the listed in Lancair's 1998 catalog as MTV-5-E. Thanks. Regards. Dave Link.
