If you do a search here on RCU you will find many posters who will not use them and many who swear by them. I've used them many times without any problem; proper installation is very important. I think when you get into the larger planes as a general rule its best to go with a hinging system other than CA hinges, such as Robart hinge points. For good instructions on how to install CA hinges, look at any Great Planes assembly manual for any plane which uses CA hinges. You can find them online at GP's website. Good luck.
