RODS

The rods, like the sail materials, have different characteristics which directly affect the performance of the kite.
There are five different basic types of stunt kite rods:

Solid Fiberglass - This is the most durable because of its high flexibility. This allows the kite to crash and bend,
but not break. Beginner kites such as the TRLBY, Beetle, and Stingray use solid fiberglass rods.

Hollow Fiberglass - This has the advantage of being stiffer and lighter, but may break on hard crashes. It has become
a very popular rod because it provides good performance very inexpensively. Kites such as the Delta Dancer use this rod.

Hollow Epoxy Fiberglass - This is the next step up in stunt kite rod. It is an epoxy resin and fiberglass wrapped together.
It is economical, durable, and relatively stiff and light. Many beginner stunt kites use them as the spine of the kites.

Pultruded Graphite - This is the most popular type of graphite rod. It is both light and stiff, which is the best combination.
This rod is created by sucking liquid graphite through a mold. Almost any kite over $75.00 will be sparred with pultruded graphite.

Wrapped Graphite - This is made from separate graphite strands wrapped around a mold. It is the most expensive, but
also the best for its weight to stiffness ratio. The hottest new rod is a wrapped graphite with tapered ends.

Graphite Framing Materials

Graphite is an excellent framing material for both kites and airplane models. It's strength to weight ratio gives it a clear advantage for building strong, lightweight flying structures. It is available in many forms for different applications. It can easily be glued to balsa wood with CA glue, creating a superb bond. It is relatively stiff in comparison with comparably sized fiberglass. In applications where a large amount of bend is required, fiberglass may be a better choice, however, fiberglass does weigh more.
