ro 347: I new to this but for me it's the smell and fumes of CA. Stinks and burns your eyes. I am using a mixture of mostly titebond, wood glue, and CA where I cannot figure out how to use wood glue. Ex I use CA to join the sheething and some of the rib parts of the wing build as I do not have enough clamps and could not figure out how to get all those ribs and spars held with 6 clamps. Where I can I use wood glue. Takes longer to cure and you need to scrape the excess globs off but other than that it is very easy to work with and cleans up with water.
