Any other motors can be mounted in plugged MMTs or their ejection charges can simply be vented overboard.
Um... because I don't know what I'm doing and haven't thought things through very carefully?Originally posted by powderburner
I think that in order to have any serious risk of rupturing the MMT you would have to use a plugged front end at the same time you use a retaining clip.....and why would you?

Without going way off thread, let me just say that I think everyone ought to be required to build at least one old Astron Sprite. The motor in this old design shifted aft at ejection but was still retained in the rocket. The new c.g. results in an unstable rocket, which tumbles back down to the ground.

One last point: to protect your rocket AFTER ignition, you should select two or three of your motors to have the desired delay charge for best recovery deployment, and put those motors in mounts that allow the ejection charges to vent forward through the rocket for deployment. Odds are, at least one of those motors will be ignited and you will have a good recovery deploy. Any other motors can be mounted in plugged MMTs or their ejection charges can simply be vented overboard.
