It's already too late. The position error was caused by the fact that I had to scratchbuild one of the struts to replace the one the carpet monster got. I didn't quite get the strut attachment level which forced the spreader bar off square. I didn't catch it until after the superglue was set

I'm so tired of this one cluttering up my workbench that I'm just going to barge ahead and finish the beast. It'll sit at the back of the shelf and look ornamental. I won't tell anyone if you won't. I also won't mention the backwards rudder stripes either.
This whole kit is an exercise in rigging anyway; I'm trying out the wire loop and stetched Q-tip turnbuckle technique on it, so I don't really care about niggling little accuracy questions on a cheapie throwaway kit.
