I have tried all the things I could find here in the forum to fix this, including: checking the nose cone base diameter is the same as the body tube, checked the automatic box on the nose cone, moved things around in the tree, etc. But still have the error. Anybody have any other ideas? I have attached the file. This is a revision from an earlier 2-stage design that had a deployment issue (AeroTech RMS-EZ early deployment) which damaged the sustainer on a single stage flight. I am making some changes to make the sustainer electronic deploy only. All that said to say that I looked back at the old file and it has the same issue.
Thanks,
