Thanks, dupes.
I have yet to glue the tracks to the road wheels, there are a couple of spots where they aren't quite meeting up. When I took the pictures, I hadn't melted the rubber band tracks together, and the left one popped off as soon as I took the Challenger out of the photo booth.
I think I'm going to get a second 40W "snake light" for the opposite side. For some reason, even with my chandelier directly above the booth, I was getting some serious yellowing on the pictures. I wonder if it has to do with the size of the booth I made, from a 24x24x18 Office Depot box. I'll have to play around with backdrops, light blue, black, etc and see what works best. I'm also using an older (but FREE) Sony DSC camera without a macro, which makes it a bit difficult to get in close.
Up next... I got the 1/72 Tamiya P-47D Razorback (one of the latest of their "Warbirds" collection) that is closed up and ready for priming. GB wise, I'm putzing with Dragon's OLD (1993) Me 1101 for the Fantasy Fliers GB. That's a beast of a kit, though, and I'm getting spoiled by Tamiya's engineering of their kits. I also have a couple other GBs, the USAAC/USAAF with AMT's mid-90s A-20G. Parts are washed, just trying to get the motivation to actually put paint to plastic on that one.
