WING SIZE & SURFACE
The wings vary in size and amount of surface covering the underside. A large wing for example 19 meters and single surface, meaning the underside is not covered, such as the wing pictured to the right, is a slow, easily maneuverable wing, very suitable for beginners.
A weight-shift-control aircraft is a vehicle, consisting of a carriage built for 1 or 2 occupants. It is powered by an engine located behind the pilot and passenger. A flexible wing and triangular control bar is attached to the carriage via a mast. The triangular control bar is used to shift the weight of the carriage in order to steer, launch or land the vehicle.
THE CARRIAGE consists of 3 wheels and tires, thus the nickname trike, with 1 or 2 seats, and mounts for the engine, fuel tank and a mast to connect the wing.
ENGINES vary in size, and are typically 2 or 4 stroke. Electric engines are starting to be installed and tested, going green as they say. Propellors can have from 2 to 6 blades.
TIRES can be large as in the picture, known as tundra tires, suitable for grass fields, sandy beaches and tundra. Large tires create a lot of drag whereas smaller tires, even bicycle tires have been used on the ultralight single seat trikes and do not create as much aerodynamic drag.
