A stunt kite has a delta design which basically means is has a triangular shape.
The wing design is created with two essential elements:

1. The structural components which form the shape
2. The size and shape of these components which define the kite performance

Structural Components A stunt kite design consists of the following structural elements:

• A spine running vertically up the middle of the kite
• Two leading edges that run on each side of the spine
• Spreaders which separate the spine from the leading edges
• Stand-offs which separate the lower spreaders from the fabric
• Fabric covering the frame
• Bridles which connect the wing to the kite lines
• Kite lines

The spine and leading edges are joined together at the top of the delta shape.
The spreaders maintain the delta shape of the kite frame and are an essential part of the kite design.
This delta frame is covered by a fabric typically made of nylon or polyester.
The kite lines are attached to the bridle.
The bridle is attached at 3 points: At each end of the lower spreader and at the leading edge attachment of the top spreader.
Performance Flight is achieved when the lift force is greater than the weight of the kite.
Weight is therefore a critical factor in kite design and fortunately one of the easiest to control.
Modern light weight materials such as fiberglass, plastics and carbon fiber provide enough strength to maintain the kites structural integrity during flight.
Fabrics such as polyester and nylon are also incredibly strong for their weight.
