Since this is the last time I¡¯ll build anything most likely, I wanted to press the easy button just once in my life. I ordered a new Titan O-340 which was delivered in June after 18 months on order. I just ordered the Sensenich 3 blade ground adjustable prop. I was considering the Catto but I wasn¡¯t real confident in their recommendation for pitch and diameter. They basically kept quoting the prop for an O-320 Tailwind. As far as I know, I¡¯m the only idiot who is building a Tailwind with a 340 so it¡¯s a guess as to prop selection. I didn¡¯t want to get into a situation where I¡¯m shipping props back and forth to CA to get it right.?
