For transparency: I've yet to see the instructions for the new 3" Estes Der Big Red Max (9721). There are no build threads, nor any flight reports that have been posted here, or anywhere I'm aware of yet. However, there is a couple of photographs on FB that shows that the shoulder for the nosecone, and it appears to match the Estes Big Daddy nosecone's shoulder.
The Big Daddy seems to have a problem with lawndarts, and I suspect there is a chance that this kit could likely suffer from the same issue if nothing has been done to improve the snugness of the shoulder. The DRM is a kind of draggy rocket, small and lightweight, and if I'm right it'll be prone to drag separation.
One thing that people can do to decrease this risk is follow the instructions carefully. I suspect that the people who are losing BDs to lawndarts did nothing to improve the fit of the shoulder. It's a small, easy to over look step in the instructions... I highlighted it in red for you...
Other modifications may be desired to be done by some, but the simplest thing to do would be to use masking tape to adjust the fit. I hope that this might help people with their kits, and prevent any lawndarts from hurting anyone, or damaging/destroying property (including the rocket).
