I used the hinges on my first RV (RV6), camlocks on my second airplane (RV8), and hinges on my 3rd and latest RV8. If I build a fourth (unlikely) it will have hinges. I was careful with installation and the pins slide in relatively easy. There is no pillowing like there can be with the camlocks, it is much less expensive, and the final look is neater in my opinion, v.s. rows of camlocks. Itís a personal preference. I can get my cowling off in 30 seconds (after removing the screws at the nose area - like we all have to do), and installation is only slightly longer, but quicker than what I experienced with camlocks. Both systems worked quite well, but I prefer the cleaner look of the hinges. I also used hinges on my wingtips. If I take my time, it will take me 30 seconds to remove, or reinstall my wingtips.
