Dihedral

Hi Ian

I believe that when conversion takes place dihedral is reduced by 50% but it depends on whether the model is high wing or low wing.
The dihedral of a wing determines the amount of self-correction capability an aircraft has in the roll axis.
More dihedral allows more self-correction at the expense of less lift, more drag and less axial rolls. Nevertheless, dihedral is sometimes necessary and is especially important for trainer aircraft.
Aircraft designs having no ailerons need dihedral in order to turn using only the rudder.
An aircraft that has no ailerons and no dihedral will tend to yaw and skid through rudder turns. Some dihedral is always required for rudder only aircraft models.
It is sometimes necessary to change the dihedral of an aerobatic design to rid the aircraft of undesirable traits such as rolling when rudder is applied (roll coupling)
