Bob/Rob,
No foul. My PS comments were not aimed at your posts at all. I was just letting everyone know what I found when I measured the wheels as I was told Kohs had some issues in this area in the past and I wanted to clear the air on the Challenger.
Rob, your comment on brain surgery is so true. This is a real problem on many of these super-sophisticated models we are seeing these days. If it breaks you're in trouble because taking one of these apart is way beyond most modelers (me included) capabilities.
