Yes stall is very viciuos if not treated right in a VAWT.
My VAWT is more related to the McDonnell Aircraft design (of 1980) than Sandia types of non-articulating VAWTs.
Yep and the McDonnell Douglas VAWT was a commercial failure and the Sandia designs are not. The document explains that straight blade VAWTs like yours need to be excessively heavy because of the forces. A VAWT like the Sandia types can be made exceptionally lightweight because the blades can be loaded in tension and they naturally stall before ripping themselves to shreads.
Your VAWT is not making much power and it keeps shredding itself to pieces. I thought maybe you'd be interested in solving those problems...

E1000:Instead of criticizing Topspeed's efforts and each answer from Topspeed; how about you show what you've built and explain why.
I've watched this thread for a bit now and TopSpeed is both building and learning.
ALL I've seen from your posts is criticism. SO instead of constantly saying why this won't work or here's what you did wrong . Show what you've done, which would to include details.
You're not yet at the number of posts that will allow you to post pictures , BUT anyone of the Moderators or Admins can assist with them if they are relevant to this post.
I also highly suggest you go to the very beginning of his posts on this and read them so you can have a better understanding of what he's doing, learning and accomplishing. Before you send another criticizing post.
