Thin CA is a mess to handle any way you cut it. I suggest, that when you use larger quantities of it, you set up a fan to the side of you to keep the fumes away. Second, your LHS sells a dispenser that has a small tube with a bulb on one end. Buy several. They are great when you get your wings all pinned together to tac with thin CA. You will love your 4*. I suggest you wait until you have done a trial CG before you drill your engine mounting holes. This kit can be tail heavy and require several ounces of nose weights. Good luck...Fred123[&:]
