Has anyone developed a brace or clamp that would support the clamshell if the structs failed or perhaps worse, if one failed? I'm quite nervous, considering the weight of the clamshell and the damage that could be done while the sailplane is in the cradle. I liked the simplicity of the Eberle trailer when I had my Libelle.

Thank, Rick

If you are really concerned about that, carry a broomstick that is cut to the correct length to fit between the U-channel top and the bottom of the inside. Wedge it in first thing after opening the trailer. Doing it on one side is enough, the top will twist if the other spring gives out but it will not collapse.
