The CG is recommended at 1 3/4" to 2" behind the spar. If you have been flying 3-D for a while I would start with the CG at 2" behind the spar. When I roll inverted my airplanes fly level with no control inputs. This is how all of my profiles are balanced.
As far as the control throws if you have a radio with dual rates set up low rate at 40% and on high rates get as much as you can get for unlimited fun. I have the file on a disk. PM me with your email address and I can send you the edge manual if you want it.
