I am building a Yank Enterprises 3 Iris. In the directions it talks about motor retention. This is my first HP rocket and have never had to worry about this so I have no idea of what to do. I dont want to use the old friction fit method. I would like to find some way to use screws and washers to hold it in. Im sure someone here can tell me what works best (for them of course).
