Stiffening up a gong wing

Postby atomic-chomik » Wed Jul 15, 2020 5:26 am

Anybody have any ideas on how to stiffen up the airframe on a gong 7m-1st gen? Or if its even possible. I thought maybe urethaning on some dacron across the LE?
Please advise and brainstorm. :lol:

I always pump my gongkites (wave and strutless) to 10 psi (or more). No need stiffen it up.
Careful with that. My Gong Pulse Wing exploded at the seams and it was never pumped over 8 Psi. And I am not the only one to whom this has happened to. Would not really pump the wings higher than 7.

I think different brands have different pressure tolerances.
I don't pump harder than the printed recommendations 8-10 on the kite except on the strutless where I go a little bit harder. I have done it for years without problems.
Check with your own kites and pump according to the recommendations.
That is a Gong Wing and is supposed to be between 8 and 10 Psi.

Yikes on the popped bladder. If anything less than 10psi, I found the wing isn't rigid enough, loses low-end pumping power by flapping.

Atomic-C is a tinkerer ... mentioned idea of sewing in loops to hold a light carbon rod, to give a little more stiffness.
