Hello Sébastien,

Pictures are worth a thousand words. That is exactly what I was talking about. One thing I noticed on the pictures is that you have attached the hinges to the doubler and not the fiberglass material. My experience with the ABC material is that it is not a good surface to adhere to specially if there is any external load on it. If you look at the pictorial instruction, you will see that they have cut that material from that area.

I am not familiar with ds8911 or ds8511, do you have the specs on them. JR website does not show them.

Thanks,
Mike
