I love the Estes plastic 18mm screw-on motor retainers. However, because they're plastic, they're a bit larger than their aluminum counterparts, such as the one from Rocketarium.
I'd like to use the Estes 18mm retainers on my BT-50 rockets, but the fact that they're a smidge wider than the BT-50 tubing bugs me. Based on my online research, it appears that the OD of the 18mm retainer from Rocketarium is narrower (by about 1-2mm) than the OD of Estes BT-50 tubing. Assuming this is correct, here's my question:
Is the OD of the Rocketarium 18mm retainer less than the ID of Estes BT-50 tubing? In other words, would the Rocketarium 18mm retainer fit INSIDE Estes BT-50 tubing?
This is a specific question, so maybe I won't get a definitive answer unless I try things out myself. But maybe someone here already knows the answer, hence this post.
