Mine seems to suffer from the helmet issue, which I am sure I can fix by shaving down some plastic on the inside: <-- Image missing/needs replaced. The head fix takes about 20 seconds. So, the left side horn (right, if you're looking at him) was rubbing on the turn on one side, and keeping things from going flush once the helmet was pulled over his head. Just shaving a few scrapes with the X-Acto knife across the lower end of that horn completely fixed it. Scrape, don't saw; just rub the blade against the back of the horn (highlighted in the picture) like you're widdling (not sawing); just a few strokes should do it. Of course, might be a different horn for you doing it, so look and see which side isn't getting clearance before you do this: <-- Image missing/needs replaced.
