After a mishap while working on my 4*40 wing (dog getting in the way and to avoid stepping on dog stepped on the wing) I am building a new wing and want to put in dual servos. I asked about this once before and one suggestion was to put two servos in the center but i really hate torque rods. I would like to mount them in a bay with a hatch. For standard servos do I need to make new hardwood ribs if I am going to use hardwood rails to moung the hatch to? Or would reinforcing the balsa ribs with lite ply and using hardwoord servo rails be better?? I think I'm also going to sheet the leading edge of the wing to help stiffen it up. Also I'm guess adding hard points to the ailerons would be good if I put the servos in the bay
