I have a H9 Edge and it will perform an elevator and harrier perfectly - sure makes me look good. Also does a wall awesome.

The setup instructions were written by Mike McConville (sp) TOC pilot. He suggests adding 3/16 inch spoilerons mixed with 3D elevator and from my experience with this plane it makes a huge difference when it comes to controlling wing rock. Without spoilerons the wings rock more frequently and a bit deeper.

Thought this might be helpful.
