Thanks. I did read the description.txt file, but I did not understand what
that part meant. Goes to show how new I am to computers. I will try it again
when I get home from work. :-))

The sail are from set 6351. So far (years of building) I have not had much
trouble at all with blades flying at a high rate of speed toward walls. :)
Ok, it has happened but with the right set up it works well. I have never had
any problems with the angel changing. The only problem is they want to slide
toward the outside of their support when theyare spinning.
After seeing the work of pixel I have been working some on rotor blades. I
have been using axels for a frame and plastic cling wrap for a skin. The cling
wrap will shink tight when a little heat is very carefuly applied. I use the
tension created by the wrap to hold the frame together. That reduses the
weight of parts I need. At the scale you are working at is it possible to use
flex tubing for blade structure?
