>>> Do you mean the fin is not straight up and down or parallel to the fuselage >>>

No Mike, that's not the direction that it is off. It slides in the slot just fine but along the top, rear of the fuse where the bottom of the fin is to be glued, the fin bottom does not come down flat on the top of the fuselage. I am making an angled ship to fill in the void.

Making sense yet?

Thanks,

Ernie
