FlyEng,

VERY nice looking work.

Yes, the Focus wing tube guides...[:@] I had the same issue with both the Focus Sport and the Focus II, and handled it the same way.

[link=http://www.rcuniverse.com/forum/fb.asp?m=9340139]Here[/link] is a link to a brief description and photos of how I did it with the Focus Sport, and I used the identical trick with the Focus II. Both are holding up well with no issues. There are other ways to do it - most involving more work and perhaps more aesthetically pleasing carpentry - but this works and is quick, and you can eyeball it with the wing tube in place and cross-check to your heart's content before committing to glue.

Also, unless yours is lot farther off than mine were, you only need do one side of the wing tube guide. It's okay if the fuse side flexes a smidge.

EDIT: Sorry umm... actually not much of a description there, but basically I think the pictures suggest how it's done. In order to mark the "box" to cut around the wing tube guide, simply stick a T-pin from the inside of the fuse to mark where the edges of the round reinforcing ply ring are, and then use a fine-tipped Sharpie to mark the box on the outside of the fuse and cut it with very sharp #11 blades. Cut a sliver from the top or bottom of the box cut-out in the fuse, depending upon whether your tube needs to be moved up or down to straighten it.
