Thanks to everyone here for all the help so far in building my first HPR rocket.
For rail button attachment, the kit directions (Madcow Twitch) say to install one button 1 1/2" from the aft end , and the other one at the CP, making sure it's behind the forward centering ring. That would put both buttons nearest the aft end of the rocket. Other info I've found online says to put the forward button much further toward the nose, just below where the nose cone shoulder ends. That makes more sense to me. What do people usually do?
The other question I have is, are the buttons supposed to spin? It seems they should, but the kit directions say to use epoxy to fix the screws in the holes, and it appears that it might be hard to do that without some epoxy getting on the backside of the button and fixing it to the body tube. Maybe just keep spinning the button after attachment until the screw hole epoxy dries?
