Hey Chris!
As usual, thanks for write-up. Always love to see how models getting built.
Just one note. I understand it is very easy to do the wing rods the way you do. Although the moment load on a graphite rod is tremendous! Looking at you wingspan and length of the rod - they look inadequate.
All those spars will stay intact while wing at the rod end could fail at a small load (at least the way I feel by looking at it) or, it could fail at rib one. Load is not spread along the spar, it is dropped (or increased) abruptly at rib one.
Do you feel the same way?
Mechanics of the load tells us simple thing - spar could be absolute null at the wingtip and should be appropriately wide and thick at the root of the wing. It saves weight and increase the maneuverability.
Not connecting spar at the root is a trade-off as far as load goes and require good load bearing rod and proper and even load distribution coming out of the rod receptacle (tube in your case).
Just a note.
Regards,
Mark
