I’m finally starting the Black Brant and run into this issue with the first stage lower fins. Although I have the Vanderburn? upgrade the problem exists even with stock fins. As you see there is an open space above the lower fins and body tube? Is this supposed to be filled in or does the real rocket have this feature? I’ve seen a detail photo on the Apogee rocket site and it looks like they built their example model this way too? Anyone dealt with this or know if this is the way it’s supposed to be built?
