this guy on youtube made a trainign stand. Its different, but it probably performs the same function. Here's the link to the video: http://www.youtube.com/watch?v=-YXNd7SSTN8

However, i think a training stand wouldn't be too useful. You can just get soem trainign gear and scoot around in the garage; that way, you can avoid crashes and still get a feel for the helicopter isntead of a tamed down movement.
