Is there an accepted rule of thumb when it comes to the cardstock centering rings that are common on low and mid-power kits?
I seem to have fallen in love with the G76G 29/40-120 reload, that crazy sound and beautiful green...absolutely lovely. I would love to throw it into a Der Big Red Max that I made earlier in my return to rocketry (stock, with Tightbond wood glue), but...
The G76 reloads have an initial thrust of about 35lbs, and I'm scared that is just going to punch right through the cardstock paper motor mounts. My DBRM has survived some F22 and F35 flights without issue, but at best that's 1/3 to 1/2 the thrust this G reload will put out. I know I could always buy another DBRM kit and laser cut some plywood mounts to do with epoxy, but...that just feels wasteful, like giving up.
Am I worrying over nothing? Has anyone ever put a G80-esque motor into a card stock motor mount and had it come back unscathed?
