aircraft is usually, though not always, built with the body consisting of a lightweight plastic material such as PVC gutter downspout or an aluminium rail.
This concept of building simple radio controlled airplanes using cheap materials without the time-consuming and painstaking process of working with balsa wood and iron-on plastic coating was popularized by a web site created in the late 1990s,[1] spadtothebone.net.
[2] SPADs are preferred to other materials because they are cheaper and are easy to work with, painting is not required, the plastic can optionally be decorated with vinyl sheets which are available in any signboard making shop at very cheap price.
Corrugated plastic planes are simpler alternative to the traditional balsa wood based R.C.
SPAD modelers make equally good advanced planes that can be made with corrugated plastic.
