Thanks, Hobbsy. This is my 4th Saito, I also have a .56, .65, and a .72. My favorite of those three is the .65, which like the .80 is the older design (larger case, brass cylinder liner, longer stroke vs. bore diameter. It too, has a lot of compression, but runs great on 15% nitro, as do the other ones. I don't really have a plane in mind for the .80. I may try to trade it at a LHS with some cash for a ZDZ 40 that I do have a plane in mind for. I just wanted to get a needle so I could run it and make sure it was in good shape, which I am sure it is.
