The rudder now bangs the elev halves at 85% throw. No binding or stress. It just looks differant . What I was trying to accomplish is distance from the rudder pushrod to the elev horn. But,,,,, it's a small change to make so I'll probably move it back tomorrow.
The hole behind the firewall is 3 1/2" inches across and 3"inches wide.
Will be too windy this weekend I'm afraid. 15 to 30mph . But,,, if I get it CG'd and the rudder servo arm reversed I wouldn't be afraid to fly it. I'm hoping the weight loss will allow me to go back to the Saito. So much more throttle managment with the 4C.
The truth is that changing the rudder location was one of the easier mods I've done to this plane. Like John from VF said,,, "It's amazing how much weight the small stuff adds up too." And that is one reason I redid this Edge. Take the throttle servo . I had a big bunch of wood and epoxy holding the first one in place. Now I have a small popcicle stick brace that is stronger and lighter .
But the main thing has been shaving and sanding everything to the point it's much lighter yet remains strong.

Update: Changed the rudder servo arm. Lost a bit of throw but it will be plenty enough.
