when i assembled my wings. i set the dihedral at zero. i checked it with a thread run from one side to the other. it originally would have had andihedral. if i did what the book said. so i called horizon and they said this was how to do it. so i believe there straight as can be. my elev. halves work together perfect. they are aligned perfect. they work together in harmony. it did this with one servo and a dave brown push rod. but i will try to move my cg to 4 inch. that i have not tried. and i have the servos on channel 2 and 8. ailevator function on my radio. ive herd to many bad things about reversers. ive tried elev to flap mixing. nothing has helped this thing. and its more frustrating when i hear of all the edges that fly so well. i really like this plane. i should say the looks of it. but its sick. do all u gys set ur dihedral zero like the book says. i can also deflect full rudder in level flight and it just yaws from one side to the other. it does not attempt to turn or roll like if it had too much dihedral. its making me sick. thanks so much for all the replys. i cant thank u all enough. if i ever get it figured out. ill post a good reply on what i had to do. again thanks so much. bill
