RE: Welcome to Club SAITO !
well i just got my used Saito 150 and wondered about the prop threads. i bought a Dubro prop nut #735 8mmx1.25 and the threads seem to be badly made. i also tried it on a Saito 100 and same thing. just goes on about a turn and i don't want to force it anymore. the older Saito 150 is 8mmx1.25 isn't it? i'm thinking that i received a defective prop nut, badly cut threads.??
