Bill, there are a few aircraft that just won't convert properly without a lot of work on your part. You've found one of them.
I've seen this sort of thing before. In that case, the display of certain parts relied on a particular animation being active and in a certain state. There was a lot of unusual scaling/rescaling in the model.
If you really want this static helicopter, then you're going to have to dig into the design, figure out what's causing the problem and then fix it. SAMM provides you with all the tools you need , but the investigation and design of the solution is up to you.
