Bubba,
I put both elevator servos in the tail just like I did on my 3W powered JBB. Havent checked the balance yet, never did check it on the 3W. I forgot to do it before the first flight and it flew good so I left it alone.
Blikseme, thanks for the tip on adjusting the screws, mine are facing the prop too, I was woondering how to do it.

Also, I pinned the firewall with dowell rods (3 per side when I first built it with a O.S. .91FX) bit that's all. It should hold up fine.
