I know we've journeyed past the dihedral topic however....with the eagle II arf you aren't given a choice of dihedral. You just glue the two wing halves together. I don't know how much it has but after gluing mine together it does kind of look silly, or not realistic. I don't want a plane with a v wing. I know that the kit allows different dihedral options. I thought my wing would look like that on the box which is straight across. I am not sure what the benefits will be with the high dihedral but I'd rather just have a normal looking aircraft. Oh well....like someone said to me before, "it's just a trainer".
