Hello can you tell what is the dihedral angle on wings and is there any angle of incidence to wings.

If yes what angle.

ali

Yes you have to fix some angle of incidence which is called pitch. ...apart from that dihedral is the angle set to the wings for auto leveling...simply dihedral is the angle between the two wing pannels.....if u are a beginner dihedral will help you a lot....these parameters are based on your design.....
