Now that's a pretty slick solution, on several counts...I hadn't really thought much about the vertical CG. I did hang it by the leadouts to check the nose-down attitude, but didn't check the wing alignment. Mine may not be as extreme as yours since my engine sits lower on the airplane--compare our pix and you can see the difference in the thrust lines. Also my wingtip dihedral may be a little more extreme than yours which would place my LOs a little higher. But I'm gonna check it closely in the AM, and if needed I will certainly adopt your solution on the LO guides. You could even move it closer to the tip and make it a little shorter too.
The struts, and BC mount, are the coolest thing. Not sure it was necessary since the LO guide location is the significant thing, as has been abundantly proved in this forum and SSW, the BC location is really sorta immaterial. Well, except for binding problems if the alignment is too far off ideal, which your setup neatly avoids. I believe I would subject it to a pull test of some kind, though, when you're all done, jjust to be sure the popsicle sticks are up to it. You also may be able to put your elev. horn on the top, which puts your up line to the front, which everyone knows is a must in these serious hi-performance stunter-type models!
I still suggest you ditch those heavy wheels for some lightweights. Weigh them--I think you'll be surprised.
Very nice, and the struts are more legitimate-looking to boot.
Race ya to the finish line?
