Good question posted in the last reply...what plane do you have?

CA is good for most building, however, CA can actually "eat" or dissolve foam parts and some plastics, so be careful where you use it. It's best to test some on any material before using it to assemble. Also, if you're building an ARF, chances are you'll be joining wing halves. For this I'd recommend using a 30 minute epoxy, as it creates a much stronger bond. Although this hasn't happened to me, I've heard stories of people's wings snapping in half due to poor joining of the wing halves.

I'm using thin and medium CA to build a J3 Cub kit right now, and I'm amazed at how the thin stuff has the ability to absorb into the wood. I accidentally bonded my elevator to the workbench!...the thin CA seeped right through the top of the elevator through to the bottom! Just be careful and you'll be okay. Also, over the counter alcohol preparations work well to remove dried CA from your fingers...trust me...it's almost impossible not to get some of it on you!

Good luck!
