Fins,

If you go to the T-One website (not the Pacific Jets website. The actual T-One website) you can download their "build manual". Not much included, but it does give you the recommended CG and I think recommended throws. I set mine at that CG and it is dead on.

The K140 is fine for power. I wouldn't go any smaller and actually would go with a 160 if I was building again just for the reserve power.

If you have any specific questions when you start the build, PM me and I would be happy to give you my two cents worth.

You will love the plane. It looks great and flies great.
