r planes were tiltedsharply upward from the center thusforming what is known as a dihedral angle.This form served to lower the center ofgravity and, it was thought, made forstability. The Wright Brothers foundthat this plan, although it lowered thecenter of gravity, caused it to move fromside to… … PLATE V. Too Large for Beginners, but Will Make Long Flights. ELABORATING MONOPLANE it in a new way. By building the modelwith three planes, each with the dihedralangle, the center of gravity has been low-ered and, at the same time, the oscillationhas been greatly reduced. The narrow-prowed form of…
