Thanks J-dubya, I could easily compensate for that additional 6oz. by strategically placing my battery. This looks promising. Just picked up some pinned hinges and I got an idea on strengthening the fire wall with some aluminum 4/40 threaded rod. I want to tee nut them to the firewall and run them in to the next former with 4/40 nuts and washers, like tension rods. There is already all the tri stock on the firewall that it will take, right from the manufacturer. Is the YS any longer than the Saito from back to spinner?

Matt, I ordered it from my LHS and its about $339.00 Thats about the same as Chief Aircraft but there is no shipping charge. I'm a little leary of used engines......I got a Saito 100 that I could sell you cheap. If it makes you feel any better, I won't tell you that it ate dirt four times already. Joe
