This week I added a link to an article outlining how to add a miniature helicopter to your film. That was the third post on miniature helicopters in this blog (the other two are here and here.) One of those old posts was about using a 1:72 helicopter model for an effects shot, and the maker of the example video has made a new attempt using as larger model (1:48) and higher quality camera. The new version references the older video and you can see the difference in quality.
