Hi, everyone. I'm new here, but been building paper models on and off for several years.

My most recent builds are the AXM Space Shuttle, namely the STS-1 full stack, and both the open and closed payload Orbiters. I decided to practice building the orbiter by making the multiple variations.

Any tips for getting the upper wing panels to lay down correctly against the fuselage? The first orbiter worked out the best. The second wasn't as great, that's the orbiter on the stack. The third looks better, but still didn't lay down as well as I wanted.

I can tell this has a lot to do with how well the lower wing is aligned with the payload bay structure. Eventually I'll figure out the details for myself, but I don't mind help.
Thanks,
Ken
