For mounting E-tronics in a bay. My opinion would be that plastic rivets would be out. There are too many ways for your e-bay to experience many Gees. and since most of our electronics are built with G10 boards. The pastic rivets would not stand a chance in any kind of shear situation. Stick with screws and nuts. Now, on the brass screw-cert business. I prefer T-nuts where I can use them. Again, with the forces involved. T-nuts will hold up better in those extreme cases than screw-certs. In most cases either work just fine.

When would plastic rivets/push pins be acceptable? Or are they? Just want to know for my own info although I will be opting for the screws.

I usually use a bulkhead on the forward end of the ebay into which I install brass inserts that will accept small screws. Before putting the brass inserts into the bulkhead you fit the bay into the airframe and drill holes through the airframe and into the bulkhead. Those holes tell you where to insert the brass inserts. Once that is done you are ready to secure the bay the the airframe with three or four screws. Again, this is my preference and there are many ways to get the job done.

I have purchased electronics bays for each. I want to get started experimenting with the electronics so I was thinking about setting up the 2" rocket with one or two altimeters, then do the timers, etc. before I put electronics into the 4". There's obviously not a lot of room in the 2" but hoping I can start with that. My question is this: should I secure the ebays with rivets or screws or should I glue them into the bodies? I kinda want to leave myself some options while I get the electronics down and dont have ebays permanently fixed. Is this a good or bad idea? Also, some of the ebay mfrs also talk about gluing one end of the ebays caps permanently to the ebay tube. Do I want to do this or leave both sides free (no glue) for easier access?
