Here is what I have done on my right wing.
It went together well.
In 1 weeks time
I have the fuselage, almost done,
horizontal stab and elevator done, except for the joiner wire
Vertical stab and rudder complete,
and this much on the right wing.

I lost almost a 1/2 hour trying to fiqure something out that was in the instructions. that I new I read, but I couldn't find it again. but after I figured it out, I saw it in the instructions.
on the right wing, rib-R1, the tab that bolts to fuselage points UP. (Thats the part it took me a little while to figure out.) Then your servo rails in your wing rib are facing up.

On the left wing, when you build it, the rib-R1 the tab that bolts to the fuse points DOWN. then the servo rails in our wing rib are facing down
