Up to know, simply making a hole in the airframe, and screwing in the screw for the rail button has worked well. On a few rockets I have put epoxy on the threads of the screw to hold everything in. Well, I was just test fitting the Raptor onto the rail. The Raptor is 4", 84" long, and weighs about 6.5 - 7 lbs. A lot of this weight is in the electronics bay, which is about 30" from the front of the rocket. Well, screwing in rail buttons didn't work. As soon as I picked up the rail, with the rocket suspended beneath, 2 buttons popped, and it fell. It has 3 buttons. One in the aft centering ring, one 5" from the bottom, and one about 16" from the bottom. What should I do to more securely mount the buttons?
