This is a question that we get from time to time. So we asked Revell's Product Development chief, Ed Sexton, who mentioned that this actually is something that has been tried in the past. The truth of the matter is the sales of the parts packs were not what we would have hoped.

As Ed states, "Many modelers realized that for a few dollars more, they could have an entire model kit and that was a better value for their modeling dollar".
