This was not just in keeping with the theme, it was a contest rocket — the contest being sport scale. But my first attempt to put it on the pad resulted in one of the launch lugs popping off — and when I put a little pressure on the other one, it popped off too. I put them back with some CA and treated them more gingerly on my next try. On a D12-5, it seemed to struggle a bit, probably in part due to the wind. Bit of a squirrelly flight. Recovery seemed to go well, but a fin popped off when it hit the ground. Well, that’s consistent with everything I’ve read about this kit — the plastic resists almost every kind of adhesive. (Tenax 7R is what I used.) Fortunately that was not a DQ under our contest rules, so I reattached the fin with CA and put the rocket aside for judging later.
