I put a fillet on top of the centering ring formerly known as rear, and while I was poking glue down there with a stick, I did put a cardboard patch over the hook slot. I’m 99.9% certain it wouldn’t have made any difference to leave it open, but it made me feel better.
With fins like these, most jigs are useless. I improvised.Given the sheer length of the fins I wanted them glued down pretty securely. So what I should have done, of course, was to ignore the Estes instructions and follow some sort of plan involving gluing on the
front rear centering ring after the fins were in place, with internal fillets. Failing to have done that, I used yellow glue for the first external fillet application — I don’t know for sure, but my guess is it’s a stronger bond than you get with No-Drip, No-Run, which I used for the final fillets.
And that’s most of what’s needed before priming. I guess the nose cone needs some attention… oh, and launch lugs, let’s not forget them. Or rail buttons? I could do rail buttons. Hm. Anyway, here’s both Mosquitos as they stand (and boy, do they ever stand):
