Okay here are some pics! Sorry for the quality it's with the wifes digicam that isn't the best.
The first picture shows the twister Both upper and lower sections of the hub are secured properly.

The second shot shows how the upper hub is separating or rotating on the blade hub upper side.
You can see how the rounded part of the hub has raised edges that should align with the flat of the hub notice how it's twisted over. This is the same as the first one I destroyed. [img]http://www.rcuniverse.com/forum/forceddownload.asp?file=1;6535668
