"And...oops, my bad again. Current project is a Legacy 40, not a Vector 40. Mine crashed, plan to build another."
That makes sense. My instructions showed the leveling bar method. Had to come up with my own way of using my jig.
"The rods through the center section will keep everything lined up. Brodak (Alan B.?) makes it even easier by having the center (W-0) rib made out of 1/4" balsa."
That's a good idea. I never had much luck in my RC days trying to mate wing panels that weren't flat bottomed. You might want to think about using 2 center ribs of 1/8". That way you could build each rib into the panel. Much easier for the LE, TE sheeting, and to glue together.
Nice Vector BTW. I like the open cockpit.
