Leester,
Hmmm. I was curious about your question since the profile Oriental I have framed up didn't use a wing jig. I just looked at the wing (refresher training) and can tell you that one the older, non-laser kit there are twin slots on both the left and right side ribs. Not really suitable for a rod-type jig in my opinion.
The latest ones according to the Brodak website are laser cut and may be different--set up to use rods. Either way, you can build it straight if you have a flat surface and a rear spar shim.
Maybe someone who has the laser cut version will chime in...?
