i need to know what type of framing i should get for something this big. i really want to reduce the amount of flexibility it will have.

What kind of kite?

Epoxy Tube is a popular and economical spar material. If you need better stiffness and lighter weight, you might want to look at Graphite.

Depending on the kite type, you might be able to use a combination of both or different diameters of each depending on the application.

I built a very large ROK a few years back that was 18' high X 12' wide.

I sticked it with Ret505 as horizontal and 610's as verticals. The 505's worked great it was light and easy. The 610's were not really very good on the ground to flexible, the kite is an outstanding flyer but tough to launch. we called it the divorce kite since my wife and I always end up yelling at each other when launching it.

We redid the center by epoxying 2 18' 610's together all along their length. This did the trick and it flys better in the higher wind. I even think I may repeat this process with the 505's since they fold a little more than I comfortable with, but they have several hundred hour of flight time on them so I'm no longer worrried about them.

If you try this you have to do each side seperately and be sure to sand and clean the outer surface to insure the epoxycan make a very solid seal. It also cost a lot to do this in both tubes and epoxy. But if you love the kite it's worth it.

Just a tip the bridal will make your horizontals work if you add enough connections. As a rule i went with a connection for ever 24 inches of span.

Good Luck.
I love seeing big Roks fly.
