Wing Dihedral for RC Airplanes

In this video I will go over what dihedral is for aircraft, why we have it and how wing dihedral should be addressed and applied for RC airplanes. In short, a complete discussion of wing dihedral for RC airplanes.

I first discuss dihedral for full scale aircraft, from Cessnas to B-777. Some aircraft have no dihedral, for example aerobatic aircraft. Certain specialized military aircraft, such as the F-104 have negative dihedral or anhedral. Again, the reasoning for these design choices are all discussed.

I show several of my radio control model aircraft and why I selected the dihedral that I did. This will help you as you either design your own radio control model aircraft or modify other designs.

Wing dihedral is a proven and easy to use technique to provide roll stability for any aircraft, to include your RC models.
