I have a Joel K Scholtz American eagle kite with carbon fiber spars. I have replaced the spars several times. But they always fail even in light wind. Is there any thing stronger than the .23” carbon fiber tubes? I hate to retire this beautiful kite but I’m done purchasing replacement spars that don’t last for even one decent flight. I carefully cut the carbon fiber tubes to length with a dremel tool so as to not spoil the integrity of the spar but no matter, the spar inevitably fails!
