Never heard of using "fletch tite." I wonder if it dries clear. When I made the statement that screws were not the way to go, I mainly meant that they were so ugly. All though the button screws don't look too bad on some applications. I have never experienced RC 56 coming loose from any ARF that I've built, (assembled) most of them aerobatic. I have 10 33% or larger aircraft that I'm flying now and they're all holding up well so far. However, if you do use RC 56, or any other type of glue, you must be sure the parts that you're glueing are clean before applying the RC 56. All canopy's have a release agent that must be wiped off before glueing. I use alcohol, and sand the bottom of the canopy before I apply the RC 56.
